Tungsten Carbide Cutting Tool Application

With the continuous progress of China's machinery, electronics, chemical industry, the rapid development of the aerospace industry and science and technology, these new tungsten carbide cutting tools are more widely used in the various areas of our production, and will bring greater economic benefits.

Tungsten carbide is currently the most commonly used in the metal cutting tool. It is with having a high heat resistance and high wear resistance of the refractory metal carbides powder as a matrix, metal Co as a binder, made after pressing by high-pressure sintering of powder metallurgy products. The point is high hardness, good wear resistance, hardness can reach 74 to 82HRC; chemical stability and good thermal stability, high heat resistance, the ability of 850 to 1000 ° C; thus allowing the use of cutting speed of up to 100 to 300m/min the carbide cutting performance, so it is widely applied. Tungsten carbide bending strength is not good, and is with poor process performance; it is rarely made use of the overall tool, generally made various shapes of blades welded or clamped in the tool body.
