る。A fastening metal fitting 6, which has an elongated rectangular plate shape when viewed from the front and has almost the same shape as the fastening metal fitting 5, is attached to the face plate 2 symmetrically with respect to the main axis 1, and is attached to the center side of the face plate 2. An elongated hole (a elongated hole elongated in the radial direction) whose width is larger than the outer diameter of the workpiece 10 is provided at the tip 6a of the workpiece 10 . Further, this tip portion 6a is formed so as to be loosely inserted into a slit of the fastening metal fitting 5.

復帰する。The chuck 9, which is equipped with a pair of clamping fittings 5 and 6 mounted on the face plate 2 in this way, has long holes that overlap due to the elasticity of the compression coil spring 8 when the main spindle 1 is stopped, so that the workpiece cannot be By driving a robot arm (not shown) holding the workpiece 10 as desired, it is easy to pass the workpiece 10 through this elongated hole and insert the center hole or the shaft center hole into the spindle side center 3. be. Then, with the robot arm holding the workpiece 10 horizontally, the psychological table can be driven forward to insert the psychological metal side center 4 into the center hole or axial hole at the other end of the workpiece 10. . After that, the grip on the robot arm is released and the robot arm is returned to its original position.

チャック９である。When the grinding is finished and the rotation of the spindle 1 stops, the elasticity of the compression coil spring 8 causes the tightening fitting 5. The clamping tool 6 approaches the axis and the chuck of the workpiece 10 is released. Therefore, after gripping the workpiece 1O with the robot arm, the psychological table is moved back and the workpiece is removed. In this way, the chuck 9 is capable of automatic cylindrical grinding.

．． The inner diameter is as small as 125++n, and the large axis hole 12 has an inner diameter of about 1mm. Therefore, the large axis center hole 12
It is relatively easy to insert the center 4 on the spindle side into the center 3 on the spindle side, but it is difficult to insert the center 4 on the psychological table side into the small axis hole 11.
