Cutting tools are the teeth of modern industry and are indispensable in mechanical processing.
Carbide cutting tools have strong comprehensive properties, combining hardness and toughness. Cemented carbide has high strength and high wear resistance. It is an alloy material composed of refractory metal carbide as the main component and metal that acts as a bonding phase. Compared with tool steel, cemented carbide has higher hardness, wear resistance and red hardness; compared with ceramics and superhard materials, cemented carbide has higher toughness. Since cemented carbide has good comprehensive properties, it is widely used in steel (P), stainless steel (M), cast iron (K), non-ferrous metals (N), heat-resistant steel (S) and hardened steel (H) materials. processing. With the optimization of important processes for tool production such as mixture preparation, molding sintering, grinding and coating, cemented carbide is widely used in the production of cutting tools and inserts. According to statistics from the China Machine Tool Industry Association, the main types of carbide tool products include carbide inserts, milling tools, turning tools, hole processing tools, etc., of which the highest proportion is used to make inserts, close to 50%.
The Carbide CR013X tool we produced for our Dutch customer was delivered perfectly.
