Please confirm the performance after material alteration.Mirror grinding is a special grinding technique, and it is applied to punch from tip to head. Compared with standard type, the processing time and cost are unchanged, And compared with lapping type, it has good wearability and anti-adhesiveness, and it is applicable for precision processing of punches. Standard tip lapping punches are applicable to precision processing of section, as well as adhesive material such as aluminum or stainless steel.The tip hardness of punch after TiCN coating can achieve 2700HV or above. And due to the material of punch is high-tensile, the wearability of tip is greatly improved.647TypeStandardTip precisionFeatureComparisonMirror grindingLappingTiCN
