Cylindrical metals such as cermet milling cutters, cermet reamers, and cermet drills have excellent wear resistance. Due to their low density and high wear resistance of cermets, they are suitable for high-speed precision machining of carbon steel, alloy steel, stainless steel and cast iron. Machining and semi-finishing (with r rounded corners work very well).
As a cutting tool, the advantage of cermet is that its material has a very low affinity with the workpiece material and has a very low coefficient of friction, so it is not easy to produce sticking tools and built-up edges, making the machined surface very smooth and flat, making it the best choice for finishing tool materials. New selection.
Cermet has excellent comprehensive properties such as high precision, high hardness, wear resistance, high temperature resistance, oxidation resistance and chemical stability, and has a good effect on the cutting and processing of specific difficult-to-machine workpieces.
After a long-distance cutting test, although the tool is 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 the traditional tool. From this comparison, it can be concluded that the service life of this tool is more The service life of other tools is 3 to 5 times, and the quality of the machined surface is better and better.
After the tool is worn, the new tool can be achieved without repeated grinding of the coating. The metal as a cutting tool has high hardness and wear resistance, and the high-speed machining effect is very good, which can improve production efficiency, prolong tool life, and truly reduce production. Cost, product finish is high, and mirror effect is achieved. Using a cermet end mill only needs to increase the speed of the original tungsten steel by about 50%.
