Cermet inserts have excellent comprehensive properties such as high strength, high hardness, wear resistance, high temperature resistance, oxidation resistance and chemical stability, and have good effects on cutting and machining of specific difficult-to-machine workpieces.
After a long-distance cutting test, although the cermet tool has been worn, it can be seen from the metallographic diagram that the tool marks are neat and the surface quality is still good, which is still excellent compared with traditional tools. From this comparison, the use of cermet tools can be summarized. The service life is 3 to 5 times that of other tools, and the quality of the machined surface is better and better.
After the cermet tool is worn, it can achieve the effect of a new tool without the need for repeated mold repair. As an advanced cutting tool, the cermet blade has high hardness and wear resistance, and the high-speed machining effect is very ideal. It can also greatly improve production efficiency and prolong Tool life, truly reduce production costs, high product finish, and achieve mirror effect. The use of high-tech metal ceramic end mills only needs to increase the speed of the original tungsten steel by about 20%.
The cermet tool is suitable for processing alloy steel, high carbon steel, structural steel and other steel parts with hardness below HRC40, especially quenched and tempered steel parts, and the surface quality is very good. In addition, 303, 304, 201, 202 stainless steel, gray cast iron, ductile cast iron and other materials are also good. Non-ferrous metals such as aluminum alloys and copper alloys can be processed, and ductile materials such as rubber and plastics can be processed.
