The work W is moved to the right at a relatively high speed (rapid feed) until it approaches the grinding wheel 13, and until the work W approaches the grinding wheel 13 until the work W separates from the grinding wheel 13. Move to the right at a slow speed (grinding feed). When the table 9 comes into contact with a stopper member (not shown) and the work W is located at a predetermined position away from the grinding wheel 13, the work W is separated from the grinding wheel 13 after the table 9 is stopped for a predetermined time. The table 9 is moved to the left until it reaches the position. The above operation is performed until the desired grinding process is completed.

Adjustment screw 73
Presses the spring 67 via the washer 71. As a result, the second transmission member 53 is pressed against the flange portion 49b of the second drive shaft 49 via the thrust ring 69 and the washer 57 by the stored force of the spring 67, and the second transmission member 53 is relatively fixed. Then, it can be integrated with the second drive shaft 49. At this time, the surface pressure corresponding to the amount of contraction of the spring 67 is generated on the surfaces A, B, and C.

ができ、その再現性が良好なものである。Therefore, the accumulating force of the elastic member 67 is
It is easy to adjust according to the weight of the upper work W, and the knob 61 is loosened so that the second actuating member 53 can be rotated relative to the second drive shaft 49. By re-tightening the knob 61 until it abuts on the second abutting portion 49c of the two drive shaft 49, the accumulating force of the elastic member 67 is surely returned to the accumulating force adjusted in advance for the weight of the work W. And the reproducibility is good.
