Rc--1003-ac8020p

Sumitomo's AC8020P is a high-efficiency, multi-layered CVD-coated carbide insert grade designed specifically for steel turning operations. Introduced as part of the AC8000P series, this grade bridges the gap between high-speed continuous machining and heavily interrupted cutting by focusing on high-strength wear resistance.
Core Technologies & Features
Enhanced Alumina Layer: Features a heavily strengthened Al2O3 (alumina) coating that significantly suppresses chipping and crater wear during high-load operations.
Mill-Scale and Forged Material Specialist: It excels at peeling tough outer mill-scale on forged materials or high-carbon steels where cross-sections or surface conditions vary widely.
Gold-Coloured Indicator Layer: The outer coating includes a gold surface finish designed to make used cutting edges instantly identifiable in dark or automated CNC environments.
Unmanned Operation Stability: Engineered with specialized adhesion-resistant surface treat...
