CNC lathe knife, car what material with the turning tool

1, high-speed steel High-speed steel is joined by more tungsten, molybdenum, chromium, barium and other alloying elements of high-alloy tool steel. Its strength is high (flexural strength is 2-3 times that of cemented carbide and 5-6 times of that of ceramic), good toughness, it can be used in occasion of impact and vibration, commonly used for processing nonferrous metals, structural steel, cast iron, High temperature alloys and other materials. In addition, high-performance high-speed steel can be used to cut a variety of difficult to machine materials, especially for the manufacture of precision tools and the beginning of complex tools.

2, Carbide Carbide is a high hardness, refractory metal carbide and metal binder sintered at high temperatures from the powder metallurgy products. It can be divided into three categories: P, K, M. See the specific form:

3, ceramic ceramics mainly alumina-based ceramics and silicon nitride-based ceramics. Alumina based ceramics have good resistance to heat, good heat resistance, high chemical stability, strong anti-adhesive ability, but poor flexural strength and toughness, which are mainly used for finishing and semi-finishing chilled cast iron and hardened steel; Silicon nitride-based ceramics suitable for machining cast iron and high temperature, I, cutting steel effect is not significant.

4, cubic boron nitride its hardness up to 800HV, its ability to carbide cutting and ordinary steel cutting speed of chilled cast iron, hardened steel, high temperature alloys for processing.

5, synthetic diamond Diamond is not a carbon stable state, easy to oxidize and graphitized heat, it must be forced cooling, it is not suitable for processing iron group elements, because the diamond carbon atoms and iron affinity, low tool life.
