Description

Machine Tools

The present disclosure relates to a machine tool that mounts a plurality of processing devices on a bed.

Conventionally, various machine tools have been proposed in which multiple processing devices are placed on a bed. For example, the machine tool of Patent Document 1 below is a so-called parallel twin-axis lathe, in which two independent beds are arranged side by side in the horizontal direction, and a processing device is placed on each of the two beds. It is Each of the two processing devices has a spindle that holds a workpiece and a tool post that holds a tool. The two beds are connected to each other by vibration dampers.

WO2010/110030

In a machine tool in which processing devices are placed on two beds, respectively, such as the machine tool described above, the operations of the two processing devices may affect each other. For example, vibration generated by driving a slide device or the like of one processing device may propagate to the other processing device via the bed and affect the processing accuracy of the other processing device. In the machine tool disclosed in Patent Document 1, the vibration suppressing device suppresses the propagation of vibration.

By the way, if the two beds described above are installed separately without being connected by a connecting member such as a vibration suppressing device, it is possible to reduce the propagation of vibration due to the driving described above. However, when the two beds are separated, there is a risk that the bed installation work such as position adjustment of the two beds will be complicated, or that the man-hours for the relocation work will increase when the beds are relocated. Therefore, whether the beds are connected or separated depends on the user's request. Therefore, there is a demand for a machine tool that can control the drive source in an optimum state depending on whether it is in the separated state or in the connected state.

The present disclosure has been made in view of the above problems, and aims to provide a machine tool capable of executing control for the motor of the drive source according to the connection state and separation state of the bed.

In order to solve the above problems, the present specification provides a first processing device and a second processing device for processing a workpiece, a first bed on which the first processing device is placed, and the second processing device. a connected state in which the first bed and the second bed are connected to each other by a connecting member; and a state in which the connecting member is removed to separate the first bed and the second bed. a bed that can be changed to a separated state; a motor that functions as a drive source for the first processing device; a receiving device that receives selection of the connected state or the separated state; The parameters are set according to the state selected by the reception device from among the state and the separation state, and the motor is driven by the parameters set during processing by the second processing device to operate the first processing device. Disclosed is a machine tool comprising: a control device for controlling;

According to the machine tool of the present disclosure, the control device sets the parameters used for controlling the motor of the first processing device to parameters according to the state selected by the receiving device. The control device controls the first processing device by driving the motor according to the set parameters during processing by the second processing device. According to this, the motor functioning as the drive source of the first processing apparatus can be controlled with parameters according to the separation state in which the beds are separated or the connection state in which the beds are connected by the connecting member. Therefore, in the connected state, it is possible to reduce the influence of the vibration generated in response to the driving of the first processing device on the processing of the second processing device. Also, in the separated state, the influence of vibration propagation is smaller than in the connected state. For this reason, the acceleration of the motor can be made larger in the separated state than in the connected state, and the production efficiency of the first processing device can be improved.

The first spindle mounting portion 53 is arranged, for example, at a rearward position relative to the position of the front surface of the first turret mounting portion 52 . The first spindle mounting portion 53 is arranged at a position spaced upward by a predetermined distance from the installation surface 71 while its left lower end portion is supported by the first turret mounting portion 52 and the first base 51 . there is Similarly, the second spindle mounting portion 63 of the second bed 43 is attached to the left side of the second turret mounting portion 62, and is positioned at a predetermined distance upward from the installation surface 71 (the first spindle mounting portion 53). The first and second

spindle mounting portions

53 and 63 are arranged close to each other with a slight gap 73 (see FIG. 5) between them in the left-right direction.

Rotate the workpiece. As with the first main shaft device 21, the second main shaft device 31 is driven by a second main shaft motor 31A (see FIG. 2) to drive a main shaft parallel to the front-rear direction, i.e., the first main shaft device. The workpiece is rotated around a main axis which is parallel to and at the same height as the main axis of 21 . The configurations of the first and

second processing devices

11 and 12 and the bed 18 described above are examples. For example, the main shaft of the first main shaft device 21 and the main shaft of the second main shaft device 31 may be arranged at different heights.

(control device 17)
The control device 17 is a processing device including a CPU 17A and mainly composed of a computer, and executes numerical control and sequence control to centrally control the operation of the machine tool 10 . The control device 17 is electrically connected to each device (first spindle motor 21A, etc.) of the machine tool 10, and is capable of controlling the operation of each device. The control device 17 also includes a storage device 17B. The storage device 17B includes, for example, RAM, ROM, flash memory, hard disk, and the like. Various control data D1 are stored in the storage device 17B.

The control data D1 includes, for example, a program for controlling the operations of the first and

second spindle devices

21 and 31 and the first and

second turret devices

22 and 32, the type of work to be produced, the type of tool used for the work, the work Data such as the position of the tool with respect to the workpiece at that time are set. The program referred to here is, for example, a sequence control program (ladder circuit), an NC program, or the like. The control data D1 also stores time constant data D2 for setting the acceleration and deceleration of a first X-axis motor 24A, a first Z-axis motor 25A, etc., which will be described later. The control device 17 executes the program of the control data D1 by the CPU 17A, and sets the time constants of the first X-axis motor 24A and the like according to the operation input of the operation panel 15 based on the time constant data D2. Details of the time constant data D2 will be described later. In the following description, the fact that the control device 17 executes the program of the control data D1 to control each device may be simply referred to as the device name. For example, "the control device 17 controls the first X-axis motor 24A" means "the control device 17 executes the program of the control data D1 by the CPU 17A and controls the first X-axis motor 24A based on the program". means that

(Control of first and second processing devices 11 and 12)
The control device 17 controls each device according to the above-described configuration to process the workpiece. For example, the control device 17 transfers the work received by the loader 13 from the device of the previous process to the first spindle device 21 of the first processing device 11 . The first processing device 11 rotates the first spindle motor 21A under the control of the control device 17 to rotate the gripped workpiece. The control device 17 controls the first turret motor 22A to rotate the first turret 22B and index the tool. The control device 17 controls the first X-axis motor 24A to move the first turret 22B in the horizontal direction. The control device 17 also controls the first Z-axis motor 25A to move the first turret 22B in the front-rear direction. As a result, the control device 17 can change the position of the indexed tool in the left-right direction and the front-rear direction, so that the workpiece can be processed into a desired shape by the tool.

As described above, the machine tool 10 controls various motors in machining operations, and executes acceleration to increase the rotation speed of the motor and deceleration to decrease the rotation speed. The machine tool 10 has two processing devices, ie, first and

second processing devices

11 and 12 on one bed 18 . Therefore, when the bed 18 is in the connected state, for example, when the first X-axis motor 24A of the first processing device 11 is accelerated or decelerated while processing is being performed by the second processing device 12, the acceleration or deceleration causes Vibration may propagate to the second processing device 12 side through the bed 18 and reduce the processing accuracy of the second processing device 12 . Therefore, the acceleration and deceleration of the first X-axis motor 24A and the like in the connected state are limited. On the other hand, if the bed 18 is in a separated state, no vibration is propagated, or the propagated vibration is extremely small, so that the above restrictions on acceleration and deceleration are eliminated or alleviated. Therefore, for example, the control device 17 receives information indicating whether the bed 18 is in the connected state or the separated state at the operation panel 15, and if the bed is in the separated state based on the received information, changes the acceleration or deceleration to the connected state. make it bigger. As a result, the first X-axis slide device 24 and the first Z-axis slide device 25 can be controlled with greater acceleration and deceleration in the separated state where the influence of vibration due to acceleration and deceleration is small, and the machining speed and machining efficiency can be improved.

second beds

41 and 43 is reduced. can be installed more stably by improving the balance of

(split state)
Next, the separated state will be described with reference to FIGS. 7 and 8. FIG. As shown in FIGS. 7 and 8, when the bed 18 is in the separated state, the connecting member 80 shown in FIGS. 5 and 6 is removed and the first and

second beds

41 and 43 are separated. For example, as described above, in the machine tool 10 of this embodiment, the acceleration/deceleration of the motor is changed according to the connected state or the separated state. Therefore, the user selects the connected state, for example, when giving priority to ease of installation/relocation. Also, the user selects the separation state when giving priority to machining accuracy and shortening of machining time.

As shown in FIGS. 7 and 8, the bed 18 is in a state where the

metal plates

84, 88 and spacers 83 shown in FIGS. 5-7 are removed. On the other hand, a position adjusting jig 90 is attached to the bed 18 in the separated state. The position adjusting jig 90 includes a front side adjusting jig 91 attached to the front surfaces of the first and second

spindle mounting portions

53 and 63 and a rear side adjusting jig 91 attached to the rear surfaces of the first and second

spindle mounting portions

53 and 63. It has a back side adjustment jig 92 . First, the front adjustment jig 91 will be described. As shown in FIG. 7, the front adjustment jig 91 includes a first position adjustment jig 91A attached to the flat portion 53A of the first spindle mounting portion 53 and a flat portion 63A of the second spindle mounting portion 63. It has a second position adjusting jig 91B attached to it.

The first position adjusting jig 91A has a first fixing member 93 and a plurality of (two in this embodiment) first adjusting members 94 . The first fixing member 93 is, for example, a substantially rectangular parallelepiped metal member that has a predetermined thickness in the front-rear direction and is long in the up-down direction in the attached state. A threaded portion 65 is formed on the flat portion 53A, for example, separately from the threaded portion 55 to which the bolt 85 of the first connecting member 81 is screwed (see FIG. 5). The screwed portion 65 is arranged vertically side by side with the two screwed portions 55 , and is formed above the screwed portion 55 . The first fixing member 93 is fixed to the flat portion 53A by a bolt 95 inserted from the front and screwed into the screwed portion 65 . Incidentally, the bolt 95 for fixing the first fixing member 93 may be the same member as the bolt 85 for fixing the metal plate 84, or may be a different member. Further, the threaded portion 65 to which the bolt 95 is screwed may be the same as the threaded portion 55 to which the bolt 85 is screwed. That is, the first fixing member 93 and the metal plate 84 may be attached at the same position.

Two holes are formed through the first fixing member 93 in the left-right direction. Each of the two first adjustment members 94 is inserted into each of the two holes. The first adjusting member 94 is, for example, a bolt having a male thread formed on its outer peripheral surface. The first adjusting member 94 may be, for example, a cylindrical metal rod (headless screw) having a male thread formed on its outer peripheral surface without a head. Female threads are formed on the inner peripheral surfaces of the two holes of the first fixing member 93 . The first adjusting member 94 is screwed onto the first fixing member 93 from the left side, and a nut 96 is screwed onto the right end protruding from the first fixing member 93 . Each of the two first adjusting members 94 adjusts its position relative to the first fixing member 93 in the left-right direction by adjusting the screwing position of the first fixing member 93 and the nut 96. be done. Also, the length (protrusion amount) of the first adjusting member 94 that protrudes to the right from the first fixing member 93 is adjusted according to the screwed position.

Similarly, the second position adjusting jig 91B has a second fixing member 98 and a plurality of (two in this embodiment) second adjusting members 99 . The second fixing member 98 is fixed to the flat portion 63A by screwing the bolt 101 into the threaded portion 66 (see FIG. 5) of the flat portion 63A. Two second adjusting members 99 (bolts or headless screws) are screwed into each of the two holes of the second fixing member 98 from the right side. Each of the two second adjustment members 99 adjusts the position to be screwed to the second fixing member 98 and the nut 102, thereby adjusting the position relative to the second fixing member 98 in the left-right direction. The length protruding to the left is adjusted.

Each of the two second adjustment members 99 is attached at the same position as each of the two first adjustment members 94 in the vertical direction. For example, flat surfaces are formed at the distal ends of the first and

second adjustment members

94 and 99 . The flat surfaces of the tips of the two first adjustment members 94 are in partial contact or surface contact with the flat surfaces of the tips of the two second adjustment members 99 . For example, if the first adjustment member 94 is pushed to the right by increasing the screwing amount of the first adjustment member 94 and shifting the screwing position to the right to make the first adjustment member 94 protrude further to the right, the second adjustment member 99 is pushed to the right by the first adjustment member 94. . Therefore, the gap 73 widens according to the amount of protrusion of the first and

second adjustment members

94 and 99 . In other words, the gap 73 between the first and second

spindle mounting portions

53 and 63 is the fixed position of the first adjusting member 94 with respect to the first fixing member 93 and the second fixing member 98 of the second adjusting member 99 . is adjusted according to the fixed position relative to the

In addition, the back side adjustment jig 92 on the back side shown in FIG. 8 has the same configuration as the front side adjustment jig 91 . Therefore, in the following description of the rear-side adjusting jig 92, the description of the same parts as those of the front-side adjusting jig 91 will be omitted as appropriate. As shown in FIG. 8, the rear side adjustment jig 92 has a first position adjustment jig 92A attached to the flat portion 53B and a second position adjustment jig 92B attached to the flat portion 63B. The first position adjusting jig 92</b>A has a substantially L-shaped first fixing member 103 and a first adjusting member 105 screwed onto the first fixing member 103 . The first fixing member 103 is fixed to the flat portion 53B by bolts 107. As shown in FIG. The first adjusting member 105 is, for example, a bolt or a headless screw, which is screwed into the first fixing member 103 from the left side (the right side in FIG. 8), and is screwed into the hole of the first fixing member 103 and the nut 109. By adjusting the screwing position, the relative position (protrusion amount) with respect to the first fixing member 103 in the left-right direction is adjusted.

Similarly, the second position adjusting jig 92B has a second fixing member 111 and a second adjusting member 113 that is screwed onto the second fixing member 111 . The second fixing member 111 is fixed to the flat portion 63B by bolts 115. As shown in FIG. The second adjusting member 113 is screwed into the second fixing member 111 from the right side, and adjusts the lateral position (protrusion amount) by adjusting the screwing position with respect to the second fixing member 111 and the nut 117 . be done. The right end surface of the first adjustment member 105 contacts the left end surface of the second adjustment member 113 . Therefore, the gap 73 between the first and second

spindle mounting portions

53, 63 is adjusted according to the amount of screwing of the first and second adjusting

members

105, 113. As shown in FIG. In the separated state, the first and

second beds

41 and 43 are in contact with only the first adjustment member 94 and the second adjustment member 99, and the first adjustment member 105 and the second adjustment member 113 of the position adjustment jig 90. are arranged with a gap 73 provided therebetween in a state in which the other portions are separated from each other. In such a configuration, the gap 73 between the separated first and

second beds

41 and 43 can be adjusted by the position adjusting jig 90 in the same manner as in the connected state. Therefore, the first and

second processing devices

11 and 12 can be arranged at the same position regardless of whether they are connected or separated. It is no longer necessary to adjust the configuration of the machine tool 10 (destination position of the loader 13, etc.) according to the connected state or the separated state.

(Parameter setting)
As described above, the control device 17 accepts, for example, the selection of whether the bed 18 is in the connected state or in the separated state on the operation panel 15, and changes the acceleration or deceleration according to the selected state. . The controller 17, for example, makes the acceleration and deceleration time constants of the motors in the disconnected state half of the time constants in the connected state. The control device 17 selects a first X-axis motor 24A, a first Z-axis motor 25A, a second X-axis motor 34A, and a second Z-axis motor 35A (hereinafter referred to as each motor in some cases) as motors whose time constants are to be changed. change the time constant for Thereby, the first and

second processing devices

11 and 12 move the first and

second turret devices

22 and 32 in the separated state with greater acceleration and deceleration in the longitudinal direction and the lateral direction. For example, in one acceleration or deceleration operation (slide feeding operation), 0. A time reduction of several seconds can be realized.

For example, when the machine tool 10 is delivered from the manufacturer to the customer and the system is started for the first time, the control device 17 accepts the selection of the connected state or the separated state on the operation panel 15 . For example, as shown in a screen 121 of another embodiment of FIG. It may be displayed on a touch panel and the selection of the state may be accepted. The control device 17 causes the CPU 17A to execute the control data D1, and retains a value indicating the connected state or the separated state using, for example, a non-volatile relay circuit (holding relay) of a ladder circuit. The control device 17 sets, for example, a value indicating 1 to the relay circuit when the connected state is selected, and sets a value indicating 0 to the relay circuit when the separated state is selected.

Then, when the NC program is executed and machining is started, the control device 17 refers to the value of this nonvolatile relay circuit and sets the time constant according to the selected state. The time constant data D2 (see FIG. 2) in the storage device 17B contains, for example, time constants to be set for each motor in each of the connected state and the separated state. The control device 17 sets a time constant used for controlling each motor based on the time constant data D2. When the value of "1" is set in the relay circuit, the control device 17 sets a value of 120, for example, as a time constant (set value of the NC program, etc.) used for controlling each motor. Therefore, the control device 17 uses the same time constant for the lateral movement control for driving the first and second

X-axis motors

24A and 34A. In addition, the same time constant is used for the longitudinal movement control for driving the first and second Z-

axis motors

25A and 35A. The first and

second turret devices

22 and 32 move forward and backward and left and right at the same acceleration and deceleration.

In addition, when the value of "0" is set in the relay circuit, the control device 17 sets a value of 60, for example, as the time constant used for controlling each motor. Therefore, the controller 17 makes the time constant in the disconnected state half of the time constant in the connected state. The time constant in the separated state is not limited to half of the time constant in the connected state, and may be a value reduced by another ratio such as 1/3 or 3/5. As a result, in the case of the separated state, the time constant used for controlling each motor is reduced (halved), for example, the time required for the rise of the current supplied to each motor is shortened, and the speed command of each motor is reduced. Increase acceleration or deceleration by shortening the response time to It is possible to shorten the movement time of the first X-axis slide device 24 and improve the machining efficiency.

On the other hand, in the case of linked specifications, the time constant used to control each motor is relatively large. For example, the time constant is set to a value such that even if vibration propagates from one of the first and

second processing devices

11 and 12 to the other, the processing accuracy is not affected or the effect is extremely small. As a result, the vibration caused by the acceleration or deceleration of the slide movement can be reduced, and the first and

second processing devices

11 and 12 can reduce the influence of the vibration caused by the acceleration or deceleration of their own device on the other device.

Therefore, the control device 17 uses time constants (set values) for changing the acceleration and deceleration of each motor as the parameters of the present disclosure. When the separated state is selected on the operation panel 15, the control device 17 sets the time constant based on the time constant data D2, and adjusts the acceleration and deceleration of each motor to those of the motors when the connected state is selected. Make it larger than the acceleration or deceleration. As a result, when the user selects the separated state in which the influence of vibration is small, the time required for sliding movement of the first and

second turret devices

22 and 32 can be shortened, and the time required for machining can be shortened.

Also, the first X-axis slide device 24 moves the first turret device 22 in the left-right direction (an example of the first axis direction in the present disclosure). The first Z-axis slide device 25 slides the first turret device 22 in the front-rear direction (an example of the second axis direction of the present disclosure) perpendicular to the left-right direction. As the motors of the present disclosure, a first X-axis motor 24A and a first Z-axis motor 25A, which are driving sources of the slide device, are employed. According to this, in the connected state, the influence of the vibration generated by the movement of the first turret device 22 on the machining accuracy of the second machining device 12 can be reduced. In addition, in the separated state, the movement time of the first turret device 22 can be shortened, and the machining time can be shortened.

The control device 17 also includes a time constant for setting the acceleration of the first X-axis motor 24A (an example of the first time constant of the present disclosure) and a time constant for setting the acceleration of the first Z-axis motor 25A (an example of the first time constant of the present disclosure). An example of the second time constant) is set. When the separated state is selected on the operation panel 15, the control device 17 reduces the time constant of the first X-axis motor 24A from the value (120) used in the connected state by a predetermined ratio (down to 60), Also, the time constant of the first Z-axis motor 25A is reduced from the value (120) used in the connected state by the same rate as the first time constant (reduced to 60). As a result, the time constant is changed at the same rate in the front-rear direction and the left-right direction, so the load of the time constant setting process and the process using the time constant by the control device 17 can be reduced. Also, the acceleration and deceleration in both the longitudinal direction and the lateral direction can be similarly increased or decreased.

Although the control device 17 changes both the acceleration and the deceleration in the parameter setting process described above, only one of them may be changed. For example, the control device 17 may increase only the acceleration in the disconnected state compared to the connected state. Also, the control device 17 increases the acceleration/deceleration by decreasing the value of the time constant in the disconnected state compared to the connected state, but the present invention is not limited to this. The control device 17 may reduce the time constant and increase the acceleration or the like in the connected state compared to the disconnected state. For example, if the bed 18 has a structure in which the vibrations generated by two accelerations are canceled by increasing the vibration that propagates in the connected state to a certain level, the control device 17 controls the acceleration and the like in the connected state. It may be increased to reduce vibration. Also, the control device 17 changes the acceleration and the like of both the first and

second processing devices

11 and 12, but the acceleration and the like of only one of the first processing device 11 and the second processing device 12 is selected. You can change it accordingly.

Also, in the parameter setting process described above, the acceleration and deceleration in both the front-rear direction and the left-right direction were changed, but the acceleration in either direction may be changed. For example, the control device 17 may change the acceleration/deceleration only in the longitudinal direction (first and second Z-

axis motors

25A and 35A). In the parameter setting process described above, as an example, the motors of the slide device, such as the first X-axis motor 24A, are targeted for setting. good. For example, the control device 17 may change the acceleration of the first and

second spindle motors

21A, 31A and the first and second turret motors 22A, 32A. Specifically, the control device 17 may increase the acceleration and deceleration of the first and

second spindle motors

21A and 31A in the disconnected state compared to the connected state.

Also, in the parameter setting process described above, only the selection of the connected state or the separated state was accepted from the user, but it is also possible to accept a change in the value of the time constant to be set. FIG. 9 shows an example of a screen 121 displayed on the control panel 15 of another embodiment. The control device 17 displays a screen 121 on the operation panel 15 to accept a change of the time constant, for example, when the system is started or when a predetermined operation input is performed on the operation panel 15 . As shown in FIG. 9, the control device 17 displays, for example, a message 123 asking, "Did you install the bed in the connected state or in the separated state?" A selection button 125 to select is displayed on the screen 121 .

In addition, the control device 17 displays on the screen 121 a display field 127 that displays the recommended time constant and a change rate display section 128 that displays the change rate of acceleration/deceleration. The control device 17 displays the recommended time constant in the state of the button selected from the

selection buttons

124 and 125 in the display field 127 . FIG. 9 shows, as an example, a state in which the selection button 124 (connected state) is selected (hatched in the drawing). The recommended time constant in the X-axis direction (horizontal direction) in the display field 127 indicates the time constant value (for example, 120) used for controlling the first and second

X-axis motors

24A and 34A. Also, the recommended time constant in the Z-axis direction (front-rear direction) in the display field 127 indicates the recommended time constant value (for example, 120) of the first and second Z-

axis motors

25A and 35A. Incidentally, when the separation state selection button 125 is selected, the control device 17 displays, for example, "60" as the recommended time constants in the X-axis direction and the Z-axis direction.

In addition, the control device 17 sets the recommended time constant (for example, 120) in the connected state to 100%, and displays the change rate of the acceleration/deceleration when the time constant is changed on the change rate display section 128 . The control device 17 accepts a change in the value of the time constant displayed in the display field 127 according to a touch operation or the like on the display field 127, and changes the rate of change of the change rate display section 128 according to the change in the value of the display field 127. do. For example, when a value less than "120" is input for the time constant, the control device 17 displays the change rate of the acceleration/deceleration that increases according to the decrease of the time constant on the change rate display section 128 . The control device 17 may receive one value (120 or the like) as the time constant for one state, for example, the connected state, and use the received value for both the X-axis direction and the Z-axis direction. Also, the control device 17 may receive time constants of different values for each of the first and second

X-axis motors

24A, 34A and the first and second Z-

axis motors

25A, 35A.

Also, the control device 17 displays an OK button 129 and a cancel button 131 on the screen 121 . Then, when the OK button 129 is selected, the control device 17 sets the time constant displayed in the display field 127 as the time constant used for controlling each motor, and uses it for machining control and the like. Also, when the cancel button 131 is selected, the control device 17 ends the display of the screen 121 . In this case, the control device 17 may display the screen 121 again at the time of the next system startup or in response to an operation input to the operation panel 15 after startup, and accept the time constant. When accepting only the selection of the state as in the above-described embodiment without accepting the change of the time constant as shown in FIG. Only 131 may be displayed on the operation panel 15 . Then, the control device 17 may accept the state selection by the

selection buttons

124 and 125 and set the time constant based on the selection by the OK button 129 .

In the above-described another embodiment, the control device 17 causes the operation panel 15 to display a screen 121 for selecting the connected state or the separated state, and displays the value of the time constant recommended in the selected state (display field 127). . The control device 17 accepts a change in the displayed recommended time constant value, and when the time constant value is changed, displays the change rate of the acceleration and deceleration of each motor from before the change (change rate display unit 128). According to this, when the machining accuracy is affected by the recommended time constant in the connected state, the user can set the time constant and adjust it to a value that does not affect machining while observing changes in acceleration and the like. In addition, in the separated state, the user can change the time constant to increase the acceleration or the like if he/she wishes to improve the machining efficiency.

By the way, the operation panel 15 is an example of the reception device of the present disclosure. The first and

second spindle devices

second spindle motors

As described above, the present embodiment described above has the following effects.
In one aspect of the present embodiment, the control device 17 sets a time constant according to the state selected by the operation panel 15 from among the connected state and the separated state, and sets the time constant during processing by the second processing device 12. The first machining device 11 is controlled by driving the first X-axis motor 24A and the first Z-axis motor 25A using constants. As a result, in the connected state, it is possible to reduce the influence of the vibrations generated in response to the driving of the first X-axis motor 24A and the like on the processing of the second processing device 12 . Further, in the separated state, the acceleration and deceleration of the first X-axis motor 24A and the like are made larger than those in the connected state, so that the production efficiency of the first processing device 11 can be improved. As a result, when installing the machine tool 10, the user can select whether the bed 18 is to be used in the separated specification or in the coupled specification, and only by operating the operation panel 15 after installation, the user can obtain the appropriate acceleration/deceleration. You can set the speed.

It goes without saying that the present disclosure is not limited to the above embodiments, and that various improvements and modifications are possible without departing from the scope of the present disclosure.
For example, in the above embodiment, a member for fixing the first and

second beds

41 and 43 is used as the connecting member 80, but the connecting member 80 is not limited to this. For example, a vibration suppressing device that reduces propagating vibration such as that disclosed in Patent Document 1 (International Publication No. 2010/110030) may be used as the connecting member. Therefore, the connection member of the present disclosure is not limited to a metal plate, bolt, or the like, and may have a vibration isolating member such as rubber.
Moreover, although the connecting member 80 is configured to fix both the front surface and the rear surface of the bed 18, it may be configured to fix either one. That is, the connecting member 80 may be configured to include only one of the first connecting member 81 and the second connecting member 82 . Also, the connecting member 80 may be configured to fix the front surface at two or more locations. Also, the connecting member 80 does not have to be provided with the spacer 83 .

Further, in the above embodiment, the time constant for changing the acceleration/deceleration of the motor is used as the parameter of the present disclosure, but the present invention is not limited to this. For example, the parameters may be the cycle of the current or voltage applied to the motor, the maximum current value, or the maximum voltage value. Alternatively, if the motor is provided with a brake device, a value for setting the strength of the brake during deceleration may be set as a parameter. Therefore, various setting values used for controlling the motor can be adopted as the parameters of the present disclosure.
Moreover, the number of processing apparatuses placed on the bed 18 is not limited to two, and may be three or more. Also, the bed 18 may be configured to be divisible into three or more.
Also, the first and second processing devices of the present disclosure are not limited to lathes, and may be other processing devices such as machining centers. Therefore, the machine tool 10 may be equipped with a parallel two-axis machining center. Moreover, as the first and second machining devices, various configurations such as a horizontal lathe, a vertical lathe, a milling machine, and a drilling machine can be adopted.
