PVD / CVD COATED CARBIDE FOR MILLING & DRILLING
GRADESA
PVD Coated Carbide (MEGACOAT / MEGACOAT NANO)
KYOCERA’s PVD coated carbides for milling and drilling utilize very tough
carbide substrates.
The low processing temperature, compared with CVD, leads to improved
bending strength, less deterioration of the coating and superior tool life with
stable machining.
CVD Coated Carbide
CVD coated carbide grades provide stable, efficient machining at high speeds
or for heavy interrupted applications.
Ti-base (TiN, TiCN) coating with superior hardness and wear resistance or
ceramic-base (Al2O3) coating with high-thermal stability is applied on a tough
carbide substrate. Superior fracture and wear resistance.
