Due to the poor rigidity, difficulty in heat dissipation, bending after heat treatment, the common sheet parts such as washer, friction plate, template and thin plate will cause clamping deformation during clamping and easy to warp during grinding. Magnetic chuck is usually used for grinding on surface grinder. After grinding, the magnetic attraction is removed and the sheet workpiece is restored to its original state, which is difficult to guarantee the machining accuracy. If the following clamping methods are used to ensure the positioning and clamping of the sheet workpiece in the free state, and the double end faces are used for grinding, good results can be achieved and the machining accuracy requirements of the parts can be achieved.
1. The clamping method of cushion elastic gasket.
2. Use temporary measures to strengthen the rigidity of the sheet workpiece.
3. Mechanical clamping mode.
4. Vacuum clamping mode.
