As shown in FIGS. 6 and 7, the setting of the oscillation speed is performed on the operation screen 66 of the touch panel display device of the control device 65. That is, the speed of oscillation is displayed on the operation screen 6 of the touch panel display device.
6, when the speed is set to N times / minute, the speed is set in the register 67.
The analog signal is converted by the D / A converter 68, amplified by the servo amplifier 69, and applied to the servo motor 43. As a result, the servo motor 43 rotates the rotation shaft 41 at a rotation speed corresponding to the set oscillation speed.
Is rotationally controlled so as to rotate. Servo motor 4

The data is converted into a digital value by the converter 70 and
Is converted into an oscillation speed, and is displayed as an oscillation speed on a monitor screen (not shown) of the touch panel display device of the control device 65.

In the embodiment configured as described above, when the workpiece W is mounted on the bed 1 and the start button is pressed, the main shaft 10 is rotated by the motor 31 at the command speed via the pulleys 32, 30 and the belt 33. You. The rotation shaft 41 of the oscillation applying device 40 is rotationally driven by the servo motor 43 via the pulleys 44 and 42 and the belt 45 at the speed N times / minute set on the operation screen 66 of the touch panel display device. Due to the rotation of the rotation shaft 41, the roller 49 eccentrically supported from the rotation center revolves around the rotation shaft 41, and periodically pushes the driven portion 21 which is a part of the link member 15 contacting the roller 49 upward. Move and link member 1
5 is given an oscillation at a speed of N times / min. As a result, the rollers 18a and 18b supported by the support portions 17a and 17b of the link member 15
7 is periodically pushed in the up and down direction, and the speed is N times / minute on the main shaft 10 which is supported on the connecting member 25 by the bearing 26.
When the amplitude S becomes twice the eccentricity e, the hinge pin 16 and the roller 49
Between the hinge pin 16 and the rollers 18a, 18
The oscillation of the distance multiplied by the ratio of the distance to b is given. Since rotational torque is transmitted to the main shaft 10 via the pulleys 32 and 30 and the belt 33, torque transmission to the main shaft 10 becomes a resistance to oscillation in the axial direction of the main shaft 10 due to the flexibility of the belt 33. Without the main shaft 10
Is given smooth oscillation while rotating smoothly. Since the rollers 18a and 18b only abut against the annular groove 27 of the connecting member 25 so as to be capable of relative displacement in a direction perpendicular to the axis of the main shaft 10, the rollers 18a and 18b are connected to the connecting member 25 and the main shaft 10 by the main shaft axis. It does not apply force in a right angle direction. In particular, the rollers 18a, 18b and the annular groove 27 move slightly relative to each other in the diametrical direction of the main shaft 10 perpendicular to the hinge pin 16 due to the swing of the link member 15, but the rollers 18a, 18b move the support shaft 1 parallel to the hinge pin 16.
Since it is freely rotatable around 9a and 19b, no force is applied to the connecting member 25 and the main shaft 10 in a direction perpendicular to the main axis at the time of joining with the annular groove 27, and the main shaft 10 maintains high rotational accuracy. be able to. Since the main shaft 10 is urged downward by the compression spring 35 via the spring receiver 36, the upper side wall of the annular groove 27 is
The link member 15 is urged to rotate in the counterclockwise direction in FIG. 2, and the driven portion 21 is constantly pressed by the roller 49. In this state, the spindle head is moved downward through the ball screw / nut mechanism 5 by the rotation of the servo motor 6, and is inserted into the machined hole of the workpiece W to perform honing of the inner peripheral surface of the machined hole. At this time, since the honing tool T is given an oscillation of an amplitude and a speed suitable for machining, the machined hole is honed with high accuracy and high efficiency.

When changing the oscillation amplitude S,
When the knob 60 of the oscillation applying device 40 is rotated,
The operating shaft 52 is driven by the screw mechanism 5 according to the rotation direction of the knob 60.
8, 59, the wedge mechanism 54,
By 55, the support 48 is moved in the left-right direction in FIG.
When the operating shaft 52 is moved forward, the support 48 moves rightward, the eccentricity e of the roller 49 elongates and the amplitude S increases, and when it is retracted, the support 48 moves leftward and the amplitude S decreases. . In order to change the speed N of the oscillation, it is only necessary to write the number N of the desired speed at the speed setting location “oscillation: ○ times / minute” on the operation screen 66 of the touch panel display device. For example, when 1000 is written, 1000 is registered in the register, and the servo motor 43
