Superhard material cutting tools in China market heating up

In recent years, with the development of machining workpiece materials, especially the appearance of difficult to machine materials, application of superhard material cutting tools is used extensively, home of superhard material cutting tools manufacturer number, size and manufacturing standards are improving fast. November 11-13th, 2011 China (Zhengzhou) international exhibition of abrasive grinding of super-hard materials and products exhibition, Fu in Henan province Zhengzhou city, Nike, bot, Zhengzhou, Zhengzhou diamond grinding, South diamond, Zhengzhou huajing, dozens of superhard materials and tool manufacturers to form showing the audience a superhard material in China's rapid development and enormous progress.

In the current tools on the market, still occupy the largest market share of cutting tool materials for high speed steel and carbide, but the hardness of these tools only 2000~3000HV, and adhesive substances, whose hardness is below 2000HV. For difficult to machine materials and finishing at high speed, and low hardness cutting tool materials have not qualified. With diamond and cubic Boron Nitride (CBN) as a representative of superhard material cutting tools quickly occupied the market. Diamond has a very high hardness and wear resistance, hardness up to 10000HV, are the most hard tool materials, thermal stability up to 700 c ~800 c. Cubic Boron Nitride's hardness is second only to Diamond (up to 8000HV~9000HV) and high thermal stability (up to 1250 ° c ~1350).

Reporter in interview in the understand to, super hard material tool has processing efficiency high, and using life long and processing quality good, features, past main for fine processing, in recent years due to improved has artificial super hard tool material of production process, control has raw materials purity and grain size, used has composite and hot process,, application range constantly expanded, except for General of fine processing and half fine processing outside, also can for roughing, in international Shang public think is contemporary improve productivity most has hope of tool material one of. Superhard materials, such as steel, cast iron, non-ferrous metals and their alloys parts, cutting speed can be an order of magnitude higher than carbide, tool life of dozens of or even hundreds of times higher than the carbide times. While its appearance, but also bring about changes in traditional concepts of technology, use of superhard cutting tool can often directly to cars, milling instead of grinding (or Polish), the hardened parts, a single process instead of multiple processes, greatly reducing process.
