Compared with carbide tools

ceramic cutting hardness up to 92-95 HRA, good wear resistance, under the same conditions for machining steel materials, its wear only P10 (YT15) Carbide Tool 1/15, the tool long life. Meanwhile, ceramic knives and steel and other metal materials, small affinity, low coefficient of friction, anti-adhesion and anti-proliferation ability, cutting knife is abrasive wheel  not easy to stick and BUE, good surface quality. Heat-resistant ceramic tool is also very good, at 1,200 ℃ can maintain 80HRA so high hardness, it is suitable for high-speed cutting at high temperatures and dry cutting, and the price is much lower than similar cutting with diamond and cubic boron nitride cutting tools. Carbide ceramics with common performance comparison of two materials.
The main disadvantage of ceramic cutting tools flexural strength, fracture toughness and low modulus of elasticity, brittleness. For a long time primarily as a finishing tool, representing the proportion of various types of tool material is small. However, the  mini flap disc last decade, the materials science and manufacturing technology, by controlling the grain size and purity of raw materials, the use of hot isostatic pressing and sintering processes and other methods (made of a sintered ceramic, its strength and Cold Pressed good hardness than in the past; while using hot isostatic pressing into the legal system of the ceramic, its dense, higher strength, resistance to chipping performance), add a variety of carbides, nitrides, borides and oxides can improve the performance of the ceramic, and  metal cutting wheel through a pellet, crystal repair, phase transformation, micro-cracks, and several synergistic toughening mechanisms to improve the fracture toughness and strength, the bending strength of the ceramic only increased to 0.9-1.0 GPa (High up to 1.3-1.5 GPa, has cemented carbide quite), and it has greatly improved impact resistance, growing range of applications, in addition to be used for general finishing and semi-finishing, it can also be used under the shock load roughing.
