When we temper non-magnetic workpieces, we use mechanical clamping, which makes it difficult to achieve and has a good effect. Several methods are as follows: 1. Use the chamfer of the workpiece to select a steel plate of appropriate thickness and shape before clamping. After grinding the two planes on the flat grinding, use the bottom plate as a base plate, then place the workpiece on the countersunk head screw. 4 (Fig. 1), the compression ring 2 presses the workpiece. It should be noted that the compression ring 2 is to be rooted or cut into the annular groove. Moreover, the workpiece to be ground should be higher than the pressing ring 2, and the height difference h=0.5 to 1 mm, and the gap b between the pressing ring 2 and the bottom plate after the clamping is b=0.1 to 0.2 mm.
