a new type of tool
As a tool for high-speed machining, it must be made of a high-hardness material with excellent wear resistance. Among these materials, ceramic is the most ideal type. Ceramic knives have high hardness under high temperature conditions, excellent resistance to plastic deformation, and are less prone to oxidative wear. However, its shortcomings are also obvious, that is, the texture is brittle and easy to damage. Recently, new ceramic varieties have been developed, and their shortcomings have been greatly reduced. For example, coated ceramics and FRC ceramics with SiC reinforcing fibers have been put on the market. Now, new ceramic tools can be used for high-speed cutting of Ni-based superalloys. Processing. Sumitomo Electric has developed a new type of tool material, which is a special ceramic coating on the CBN200/CBN80 (cubic boron nitride sintered body). This special coating improves the wear resistance of the material by 30%. Tool life has been greatly extended. This new tool is mainly used for high-speed machining of high-hardness hardened steel and cast iron commonly used in the automotive industry.
