The surface of the grinding wheel should be cleaned; 3. The amount of grinding each time, Do not exceed 0.013 mm. Excessive grinding will cause the surface of the metal stamping die to overheat, which is equivalent to annealing treatment, which makes the die soft and reduces the life of the die; 4. It is best to use a loose, coarse-grained, soft grinding wheel. 5. When grinding, ensure that the punch and the lower die are fixed and stable, and special fixtures and fixtures should be used; 6.
