1.MC is a fixed-size grinding method: the height tolerance of any point of the square chuck W, X, Y, Z of the same specification is within 0.05mm.
2. MC specifications can be replaced with raw claws to process irregular shapes and replace a large number of jigs on the central machine, which is more economical and convenient.
3. The precision tolerance of repeated clamping by hard claws is within 0.02mm.
4. After side parallel correction, the parallel tolerance of the hard claw clamping is within 0.05mm.
