Further, since the memory unit 21 for storing the positions of the J-th and second shoes 5 and 6 in the y-axis direction and the y-axis direction is provided, the workpiece processing conditions and the like can be obtained in advance by actual polishing or the like. At the most appropriate shoe position, the shoe position is stored in the memory unit 21, and the stored yaw and yaw axis positions are reproduced, whereby the positioning of the shoe can be easily and surely performed. Further, since the position of the first and second shoes 5 and 6 corresponding to the processing condition information is stored in the memory unit 21 in the two-axis direction, the position in the two-axis direction corresponding to the processing condition information can be reproduced, and the position can be accurately performed. Higher degree: position control. Further, the drive control unit 20 drives and controls the second and second moving mechanisms ίο and η so that the second shoe 5 and 6 move as the diameter of the workpiece W changes, so that the amount of polishing increases. It also ensures the most appropriate shoe position and improves the grinding accuracy. In addition, the drive control unit 20 drives and controls the first and second moving mechanisms 1A and u so that the pressing force applied to the workpiece W by the second and second shoes 5 and 6 becomes a predetermined pressure, and therefore can be controlled to The pressing force corresponding to the rigidity of the workpiece w, and thus the point, can also improve the grinding precision. In addition, in the conventional grinding machine, when performing the outer diameter grinding and the inner diameter grinding, it is necessary to have the outer diameter rough processing tl 'the inner diameter rough processing, the outer diameter final processing t3 'the inner diameter final processing t4 step 4 In the present embodiment, since the position adjustment of the first and second |fb 5 可 can be automatically performed, as shown in FIG. 3, it can be changed once again.疋Preparation ^Continuously performing the aforementioned four steps tl JL t4, the productivity can be further described in the first embodiment, as shown in Fig. 1, the i-th boot 5 is set to rotate slightly closer to the straight line C. The direction is on the upstream side, and the second = is set to the upstream side of the straight line ,, but the most appropriate position of the first and second rails in the present invention is not limited to the position of the first figure, and the figure 4 is shown. It is also possible to set the second 6th to the more upstream side. Further, when the i is polished, the first shoe 5 may be disposed at a position facing the red turning wheel 4 as shown in Fig. 5. In the above-described embodiments, the case where the second and second boots 5 and 6 are placed is described.
