For machining of steels and stainless steels MC7020 The micro-grain wear resistant Al2O3 and fibrous TiCN layers deliver excellent wear resistance in high speed cutting. Use of a specially developed cemented carbide that provides superior resistance to fracture and thermal cracking prevents the cutting edge from sudden fracturing. For machining of stainless steel MP7030 MP7030 has a multi-layer coating based on newly developed Ti-compound. It provides superior wear and fractureresistance in stainless steel machining. Multi-layercoating K A special tough cemented carbide substrate gives excellent performance in machining of difficult-to-cut materials such as stainless steel. Special substrate Heat-resistant Alloy, Cutting For Titanium Alloy MP9130 MP9140 An enhanced super fine cemented The new technology carbide substrate has increased Al-(Al, Ti)N coating provides toughness while maintaining hardness. stabilisation of the high The Al-Ti-Cr-N accumulating coating hardness phase and succeeds ensures optimum heat and wear in dramatically improving wear, resistance. The combination of these crater and welding resistance. properties gives excellent fracture resistance and welding resistance because of low coefficient of friction when machining titanium alloy.
