Coated To Improve Tool Key Technology

Tool coating technology has made significant progress in recent years. Chemical coatings (CVD) remains the indexable inserts the Carbide milling inserts major coating processes, has developed a medium-temperature CVD, Al2O3, transition layer of thick film and other new technology, based on modified substrates, CVD coating for increased wear resistance and toughness; also made great progress in CVD diamond coating improves coating surface Cermet Inserts finish, and entered the practical stage. At present, the foreign proportion of coated cemented carbide indexable has amounted to more than 70%. This during, physical coating (PVD) of progress is striking, in coating furnace structure, and process process, and control technology, aspects are made has new progress, not only development has applies Yu high-speed cutting, and dry cutting, and hard cutting of high heat sex coating (as Super TiAlN) and integrated can better of TiAlCN General coating and DLC, and W/C reduction motorcycle coating, and through on coating structure of innovation, development has Nano, and multilayer structure, significantly improve has coating hardness and toughness.
