The AC6030M grade incorporates Sumitomo's specialized Absotech Platinum CVD coating, featuring an ultra-smooth, highly oriented Alumina layer that reflects heat back into the chip and drastically lowers friction coefficient to eliminate adhesive welding.\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 ideal way to resolve stringy chip bird-nesting when turning long austenitic alloys?\u003c\/p\u003e\n\u003cp style=\"margin: 0; padding-left: 15px; font-size: 13px;\"\u003eA: Ensure your depth of cut ($a_p$) stays above 0.8mm to engage the open chip pocket of the -GU geometry.
