Ceramic cutter is a special kind of knife, which is made of ceramics with excellent performance A knife made from raw materials.
Most of the ceramic cutters on the market are made of a nanomaterial "zirconia". Zirconium oxide powder is pressed at a high temperature of 2000 degrees with a 300-ton heavy pressure and a mold to form a knife blank, which is then polished with diamond and fitted with a handle to make a finished ceramic cutter.
Features of ceramic cutters:
1. It has good wear resistance and can process high-hard materials that are difficult or impossible to process with traditional cutters, thus eliminating the power consumed by annealing; and therefore can also Improve the hardness of the workpiece and extend the service life of the machine and equipment;
2. It can not only rough and finish machining of high-hardness materials, but also perform high-impact tasks such as milling, planing, interrupted cutting, and rough turning of blanks. Processing;
3. The friction between the ceramic cutter and the metal is small when cutting, and the cutting is not easy to adhere to the blade. It is less likely to produce built-up edges and can perform high-speed cutting. Therefore, under the same conditions, the surface roughness of the workpiece is relatively low;
4. The durability of ceramic cutters is several times or even dozens of times higher than that of traditional cutters, which reduces the number of tool changes during processing and ensures the small taper and high height of the workpiece being processed. Accuracy;
5. High temperature resistance and good red hardness. It can cut continuously at 1200℃. Therefore, the cutting speed of ceramic cutters can be much higher than that of cemented carbide. It can perform high-speed cutting or realize "turning and milling instead of grinding". The cutting efficiency is 3-10 times higher than that of traditional cutters, achieving the effect of saving 30-70% or more of working hours, electricity, and number of machine tools;< /div>
6. The main raw materials of silicon nitride ceramic cutters are nitrogen and silicon, which are abundant in nature. Using it instead of cemented carbide can save a lot of W, Co, Ta and Nb, etc. Important metals.
