CVD grades like AC6020M are harder and better suited for continuous, high-speed turning. Choose AC630M when your process experiences edge chipping or unexpected fracture under heavy shock loads.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px;\"\u003e\n\u003cp style=\"margin: 0 0 5px 0; font-weight: bold; color: #47479f;\"\u003eQ: What is the optimal operational range for the LU chipbreaker when turning stainless steel?\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding-left: 15px; font-size: 13px;\"\u003eA: The LU chipbreaker features a highly reinforced land width designed for high-feed roughing at deep depths of cut (ap \u0026gt;= 1.5mm). If you drop the depth of cut below 1.0mm, the stringy stainless chip will bypass the deflector groove, causing long ribbons. For light finishing or medium cutting, select the GU or EM chipbreaker profiles instead.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 15px;\"\u003e\n\u003cp style=\"margin: 0 0 5px 0; font-weight: bold; color: #47479f;\"\u003eQ: Is flood coolant required for machining stainless steel with the AC630M grade?\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding-left: 15px; font-size: 13px;\"\u003eA: While the Absotech PVD coating provides excellent thermal protection, flood coolant is highly recommended for roughing stainless steel. Continuous coolant delivery aids in chip evacuation, lowers the zone temperature to prevent work-hardening, and extends tool life.
