Ceramics, with high - pressure precision ceramics developed. Tools made of ceramic materials are called ceramic tools.
Advantages of ceramic tools
1. Good wear resistance can be processed traditional tools difficult to process or simply can not process the high hard materials, so can avoid the power consumed by annealing processing. Therefore, it can also improve the hardness of the workpiece and extend the service life of the machine.
2. It can not only rough and finish high hardness materials, but also milling, planing, intermittent cutting, rough drawing and other processing with great impact force.
3. Ceramic blade cutting with metal friction, cutting is not easy to adhere to the blade. Therefore, under the same conditions, the surface roughness of the workpiece is relatively low.
4. Tool durability than the traditional tool several times or even dozens of times, reduce the number of tool change in processing, to ensure the small taper and high precision of the processed workpiece.
5. High-temperature resistance, red hard good. The cutting speed of the ceramic tool can be much higher than that of hard alloy. It can be used for high speed cutting or "turning and milling instead of grinding". The cutting efficiency is 3-10 times higher than that of traditional cutting tools. It can save time, power and machine tools by 30-70% or more.
6. Silicon nitride ceramic tool's main raw material is nature is very rich in nitrogen and silicon, with it instead of hard alloy, can save a lot of W, Co, Ta and Nb, and other important metals.
