Inserts for Hard-to-machine Materials Machining
CAEC has developed special grade GY83,GY87,GY03, and GY08 for turning and milling by adding rare earth (RE) and applying special sintering processing. Products demonstrate excellent toughness and wear resistance after PVD and CVD composite coating, mainly applied for high-temperature alloy, titanium alloy and stainless steel milling, widely used in milling and turning of steam turbine, blade of aircraft engine, casing and other hard- to -machine materials. The coating has high anti crater wear resistance and flank wear performance in dry milling of stainless steel.
