Can ceramic tools process cemented carbides?
No, ceramic cutters are usually used to process cast iron (high speed machining) and high hardness steel (Cui Huogang).Generally, the hardness of ceramic tools reaches HRA91-95, while the hard alloy can reach HRA93.The main components of ceramic tool materials are Al2O3 with high hardness and melting point. Si3N4 and other oxides and nitrides, and then added a small amount of metal carbide, oxide or pure metal additives, formed by pressing, sintering, and then a tool material. Its hardness can reach HRA91 ~ 95, and the hardness of HRA80 can still be kept at the cutting temperature of 1200 DEG C. In addition, the chemical inertia is large, the friction coefficient is small, and the wear resistance is good, and the service life of the processed steel pieces is 10~12 times of that of the hard alloy.Its major disadvantages are brittleness, low bending strength and low impact toughness. Therefore, it is mainly used for semi finishing and finishing, high hardness, high strength steel and chilled cast iron and other materials. Commonly used ceramic cutting tools are alumina ceramics, composite alumina ceramics and composite silica ceramics.Taiwan is hard gold metal carbide with high heat resistance and high wear resistance (WC tungsten carbide, titanium carbide, tantalum niobium carbide TiC TaC, NbC etc.) and metal binder (cobalt, nickel and molybdenum) powder metallurgy products under high temperature sintering. The hardness of HRA8 9 ~ 93, 850 ~ 1000 DEG C high temperature resistant, has good abrasion resistance, allowing the use of the cutting speed can reach 100 ~ 300m / min, can be a variety of materials including machining hardened steel, therefore it is widely available.
