Solution
Rough, fine and mirror processing are divided into multiple parameters.
1. After rough machining, choose 1.5A for machining, leaving 0.02 mm allowance.
2. Finishing, processing at 1A and 0.7A, the removal allowance is about 0.007, 0.1A is processed to the upper tolerance, and the finish is matte.
3. Mirror surface processing, Mitsubishi machine processing, the processing volume is about 0.001-0.002mm.
