The spindle unit 15 includes, for example, a drill processing unit, an end mill unit, a tapping unit, etc. that have a motor and have a rotational drive function and a feed function.
These units are fixed to the block 14, for example, by the method shown in FIG. That is, the taper hole (circular cross section) 141 whose diameter increases downward is formed as an attachment hole penetrating the block 14. A unit casing 151 is inserted into the tapered hole 141 from below and fixed with a C ring 142. The C ring 142 is inserted into the circumferential groove 152 of the casing 151. A part of the casing 151 has the same shape (tapered shape) as the tapered hole 141 and is firmly fixed even if an external force is applied from below the block 14. As a result, high-precision processing is possible. There are a fixing method in which the casing is baked into the mounting hole of the block 14 and a method in which a male screw is formed on the outer surface of the casing and this is fixed to the block with a sleeve-shaped female screw.
Further, a milling unit is suspended from the tool support block 14 at a predetermined position. FIG. 6 shows an example of a drilling unit, and FIG. 7 shows an example of a milling unit. Each unit includes a spindle motor that drives a drill or a mill, a ball screw for feeding, a servo motor, and the like. For example, in a state where the rotor is rotated at a high speed, a processing tool (drill, tap, milling) fixed to the tip of the spindle is pressed against the workpiece by a fluid cylinder to perform desired processing. The drive control of each unit is performed by a controller (not shown). As such a thin shaft spindle unit, for example, a mechanical feed drill unit ZSSV type, ZSSHV type, ZSV type, ZMV type, ZLV type, etc. manufactured by Tac Giken Co., Ltd. can be used. Also, the company's drill tap units TSD, TSSD type, etc. can be used.
A second spindle unit 18 having a horizontal output shaft is disposed on the side of the XY table 12 in the gantry 11.
The second spindle unit 18 is disposed at a predetermined position on the gantry 11 via a holder 19. Similarly to the above, the second spindle unit 18 may be a drill unit made by Tac Giken Co., Ltd. for drilling holes or a tap unit for tapping. Further, the arrangement position and the number thereof may be on both sides of the table, one side, one or two. It arrange | positions corresponding to the workpiece | work WK.

The drive control of the plurality of spindle units 15 and the XY table 12 is operated by an operation panel 23 provided in the casing. Moreover, although not shown in figure, the supply and discharge of the cutting oil on the XY table 12, and the discharge of scrap are also comprised similarly to a general purpose machine. Moreover, supply and discharge of the workpiece can be performed manually.

A method for manufacturing the NC multi-spindle multifunction machine 10 according to the present invention will be described below.
First, a plurality of mounting holes 17 are formed in the tool support block 14 according to the shape of the workpiece WK to be processed. Specifically, the type of the spindle unit 15 and its planar arrangement position are determined according to the position, size, depth, etc. of the through hole, screw hole, and burr generating portion in the work WK, and the tool support block 14 is formed with a mounting hole 17 having a size corresponding to each of these positions.
Further, if the target work WK is different, for example, when the hard disk casing is changed to the case back cover of the personal computer, the size and arrangement of the mounting holes 17 of the block 14 are changed in accordance with the hole positions. For example, FIG. 8 shows three examples in which the positions of the mounting holes 17 are varied depending on the shape and configuration of the workpiece WK. The spindle unit 15 is appropriately attached from the thin shaft to the very thin shaft according to these blocks 20, 21, and 22.
Then, a plurality of spindle units 15 are inserted into the corresponding mounting holes 17 (tapered holes) and attached. That is, the plurality of spindle units 15 are respectively fixed to the plurality of mounting holes 17 of the tool support block 14. The drilling unit described above is arranged and fixed as designed in, for example, a mounting hole for forming a through hole, and the tapping unit is fixed in a mounting hole for tap formation as designed. Further, the milling unit is also attached to the tool support block 14 in a suspended manner.
Specifically, each unit is firmly attached by inserting the unit main body (casing) into the corresponding mounting hole 17 (tapered hole 141) and using the C ring 142 or a fixture including a predetermined bolt, nut, and the like. Fix it. In this case, each unit is precisely positioned and fixed in the vertical direction and in the plane in the block 14.
Further, a tool support block 14 (a block corresponding to a specific workpiece) on which a plurality of spindle units 15 and the like are mounted is attached to the column 13. The block 14 is positioned by a plurality of guide pins 16 projecting from one end surface of the block 14, and firmly and precisely fixed by a fastener (not shown). As a result, the tool support block 14 is disposed at a predetermined height above the XY table 12 and its lower surface is arranged in parallel with the upper surface of the XY table 12.
Further, a second spindle unit 18 having a horizontal axis is arranged on the side of the XY table 12 via a predetermined holder 19.
As a result, a plurality of drilling units are arranged on the XY table 12 and on the sides thereof with, for example, the thin shaft spindle units 15 having different diameters separated by a predetermined interval.

Next, a method for processing the workpiece WK using the NC multi-spindle multifunction machine 10 will be described.
First, as described above, the types of the plurality of spindle units 15 and their planar arrangement positions are determined in accordance with the positions, sizes, depths, and the like of the through holes, screw holes, and burrs in the specific workpiece WK. A plurality of attachment holes 17 are formed in the tool support block 14 for attaching the plurality of spindle units 15 and having a size corresponding to each position corresponding to the arrangement position. Then, the tool support block 14 in which the plurality of spindle units 15 are inserted into the corresponding mounting holes 17 and attached is attached to the column 13.
Here, in the NC multi-spindle multifunction machine 10, the work WK is placed on the XY table 12 and held. For example, hold firmly with a clamp. Or it adsorbs at a negative pressure.
Next, by operating a switch or the like on the operation panel 23, the plurality of spindle units 15 are simultaneously driven to perform predetermined machining on a desired plurality of parts of the workpiece WK. Work with multiple tools or blades at the same time. Further, the workpiece WK is simultaneously processed even when the second spindle unit 18 disposed on the side of the XY table 12 is used.
As a result, using the multi-axis spindles 15 and 18 assembled for a specific workpiece WK, machining of a highly accurate hole or the like at a desired position of the workpiece WK is performed in a short time. The work WK is supplied to and discharged from the multifunction machine by a mechanism (not shown).
In addition, when it is not possible to process all of the workpiece by one machining process, the XY table 12 is driven to obtain the final product workpiece WK by the second machining. For example, when the holes are so close that they cannot be drilled at the same time.

10 to 13 show another embodiment of the NC multi-spindle multifunction machine according to the present invention. The multifunction machine in this embodiment is configured so that two workpieces can be mounted on the XY table 100 simultaneously. Above the pair of workpieces, a tool support portion (a cast iron block) 101 is horizontally disposed so as to be cantilevered by a column. The tool support unit 101 includes a plurality of types of spindle units 102 having different vertical sizes, a second spindle unit 103 having a horizontal axis, and an oblique axis (for a horizontal workpiece). A third spindle unit 104 having an axis inclined at 30 to 60 degrees is provided. Each tool unit 102, 103, 104 is arranged corresponding to a work to be processed. Further, these units are set in the block 101 via mounting holes (the taper holes may be used), and are centered and positioned. This block 101 is a rectangular body having a predetermined thickness, and sleeves 110 at both ends in the length direction are inserted into vertical guide pins 111 (standing on a part of the column) and accurately positioned and fixed. . Furthermore, the drive of each unit is program-controlled in the control panel. Other configurations such as an XY table are known mechanisms, or are substantially the same as in the above-described embodiment.
Therefore, in the multifunction machine according to this embodiment, two workpieces are simultaneously processed in block 101 by NC control. When it is difficult to process the workpiece once, the processing to the predetermined part is performed by processing twice or more. For example, after drilling with a drill unit, the edge portion is milled. In addition, drilling in an oblique direction can be performed at the same time. By changing the angle of the clamper in this oblique axis direction, for example, it is possible to correspond to the workpiece.
Therefore, if the workpiece is different, for example, if the workpiece is changed to a different substrate or casing, it is changed to another block in which a unit corresponding to this is incorporated. The design of the position and size of the mounting hole of the block to be replaced corresponds to a new workpiece.
