With the development of modern science and technology and production, various new difficult-to-machine materials are widely used in products. Traditional cemented carbide insert materials have been difficult to meet the production needs, while ceramic non-standard blade materials have excellent heat resistance. It is favored by people for its wear resistance, good chemical stability and high cost performance. Especially in the field of high-speed cutting and difficult-to-machine materials, it shows the advantages that traditional blades can't match.

Compared with non-standard blade cemented carbide materials, non-standard blade ceramic materials have a hardness of 92-95 HRA and good wear resistance. When machining steel under the same conditions, its wear is only P10 (YT15) carbide inserts. 1/15, long tool life. At the same time, non-standard blade ceramic materials have low affinity with metal materials such as steel, low friction coefficient, strong anti-adhesion and anti-diffusion ability, and are not easy to stick and produce built-up edge when cutting, and the surface quality is good. The heat resistance of the ceramic blade is also very good. It can maintain high hardness of about 80HRA at 1,200 °C, so it is suitable for high-speed cutting and dry cutting at high temperature, and the price is far lower than the diamond and cube with similar cutting performance. Boron nitride tool.

There are dozens of varieties of ceramic blade materials. Different types of ceramic non-standard blades have different application ranges. Therefore, the types and grades of non-standard blade ceramics must be correctly selected to match the materials to be processed. In addition to meeting technical requirements, economic and environmental performance requirements should also be met.
