Ceramic cutting tool characteristics
1, good wear resistance, can process the traditional tool is difficult to process or can not process the high-hard materials, which can be exempted from the annealing processing power consumption; and therefore can also improve the hardness of the workpiece to extend the life of machinery and equipment;
2, not only for the high hardness of the material rough, finishing, but also for milling, planing, intermittent cutting and blank rough rough roughing and other large impact processing;
3, ceramic cutting blade and metal friction, the cutting is not easy to bond on the blade. Bugs are not easy to produce, plus can be high-speed cutting. So the same conditions, the workpiece surface roughness is relatively low.
4, the tool durability than traditional tools several times or even several times, reducing the number of tooling in the processing to ensure that the workpiece is a small taper and high precision;
5, high temperature, good red hardness. Can be continuous cutting at 1 200 ℃, so the cutting speed of ceramic cutting tools can be much higher than the cemented carbide. Can be high-speed cutting or to achieve “car, milling and grinding”, cutting efficiency than the traditional tool 3-10 times higher, to save hours, electricity, machine number 30-70% or higher results;
6, silicon nitride ceramic cutting tool is the main natural material is very rich in nitrogen and silicon, use it instead of carbide, can save a lot of W, Co, Ta and Nb and other important metals.
