Together with the chuck 2, rotates the frame 1, which is the workpiece, at high speed. Then, the stage 4 moves in the X and Y directions, and the first bite 5 attached to the stage 4
Roughens the bearing hole 1B. At this time, the inner diameter D1 of the sleeve shown in FIG. 11 is cut with a precision of about ± 2 μm with respect to a predetermined dimension. Next, the spindle 3 is temporarily stopped, the stage 4 moves in the X and Y directions,
As shown in FIG. 2, the groove machining tool 6 is inserted into the bearing hole 1B, the spindle 3 is slowly rotated in the CW and CCW directions in the drawing, and the right screw or the left screw is tightened or loosened to move the A fish-bone shaped pressure groove 1C is plastically worked on the inner diameter by the 1 ball 6A. Next, the stage 4 moves in the X and Y directions, the spindle 3 rotates at high speed, and the second bite 7 is inserted into the bearing hole 1B as shown in FIG.
The inner diameter D2 shown in (c) is finished. Then, as shown in FIG. 4, the second balls 10 supplied from the hopper 11 are fed.
Has a diameter slightly larger than the bearing hole 1B by a few micrometers, and the pressing element 8 is a frame 1 to be processed.
The load detection means 9 such as a load cell detects the press-fitted load at this time, and the computer 15 calculates the inner diameter of the bearing hole 1B by calculation from the detected load. The diameter difference between the second ball 10 and the bearing hole 1B is slight, and the sleeve 1A receives stress within the elastic limit but does not permanently deform. After that, the second ball 10 is recovered from the chute 12 into the recovery container 13 through the hole 2A of the chuck 2 as shown in FIG. And computer 15
If there is an error between the calculated inner diameter and the predetermined inner diameter,
If necessary, the second cutting tool 7 shown in FIG. 1 or FIG. 3 can be used to increase the depth of cut and process again, or to automatically change the depth of cut thereafter. According to the present invention, such reworking and automatic change can be performed while the workpiece 1 is chucked by the chuck 2. Reference numeral 1 in FIG. 8 denotes a frame which is a workpiece after the processing is completed.
