Situation tool superhard materials market development analysis

In recent years, with the continuous development of machining the workpiece material, especially some appear difficult to machine materials, superhard materials tool has been more widely used, the domestic manufacturers of hard material tool number, size and manufacturing standards are in rapidly. In 2011 China (Zhengzhou) International Exhibition of superhard abrasive grinding materials and products exhibition, Henan rich Nike, Zhengzhou Bot, Zhengzhou three mill, Zhengzhou diamonds, South Africa diamond, Zhengzhou, China Crystal and dozens of superhard material and tool manufacturers jointly to show the audience the rapid development and enormous progress domestic superhard materials.

In the current tool market, accounted for the largest market share of the tool material remains high speed steel and carbide, but these tools highest hardness of only 2000 ~ 3000HV, if coupled with an adhesive substance, its overall hardness in 2000HV less. For difficult materials and high-speed finishing, the lower hardness of the tool material are not competent. Diamond and cubic boron nitride (CBN) as the representative of superhard material tools are quickly occupied the market. Where the diamond has a very high hardness and wear resistance, hardness up 10000HV, is the hardest tool materials, thermal stability up to 700 ℃ ~ 800 ℃. The CBN hardness only to diamond (up to 8000HV ~ 9000HV), and higher thermal stability (up to 1250 ℃ ~ 1350 ℃).

In an interview that, superhard materials processing tool with high efficiency, long life and good processing quality and other characteristics, mainly used for finishing last in recent years because of improved production technology of artificial superhard cutting tool materials, control of the raw materials purity and grain size, the use of composite materials and hot-pressing process, etc., constantly expanding range of applications, in addition to the general suitable for finishing and semi-finishing, but also for roughing, internationally recognized as the most contemporary improve productivity one promising tool materials. Use of superhard materials processing steel, cast iron, non-ferrous metals and their alloys and other parts, cutting an order of magnitude higher than the carbide, carbide tool life than dozens or even hundreds of times higher. At the same time it appears, but also the concept of the traditional craft changes, the use of super-hard tool can often be directly in cars, milling and grinding (or polished), hardened parts processing, can be used instead of a single multi-step processes, greatly shorten the process .

Nike superhard materials Co., Ltd., Henan Fu Tai chief engineer Zhang told reporters, diamond cutting tool material with high hardness and wear resistance, can effectively processing of copper, aluminum and other nonferrous metals and alloys, ceramics, sintered hard end alloy particles of various fiber reinforced composite materials, and the like. Cubic boron nitride and diamond compared to higher thermal stability, chemical inertness of the iron group element, strong anti-blocking ability, is more suitable for processing a variety of hardened steel, hot spray material, chilled cast iron and more than HRC35 cobalt-based and nickel-based and other difficult to cut materials.
