carbide cutting tools in the developed countries have already accounted for dominant position of cutting tools

In developed countries, at present, the carbide cutting tools has dominant position of cutting tool, the proportion of 70%. And high speed steel cutter is shrinking at an annual rate of 1% ~ 2%, the proportion has dropped to below 30%. Diamond, cubic boron nitride superhard cutting tools such as the proportion of about 3%. Domestic hardware manufacturing consumption of cutting tools, carbide cutting tools has reached more than 50%, proportion of supply and demand structure of disjointed problem is very serious. The consequences is a large surplus of high speed steel cutting tools export or domestic sales at a low price, efficient carbide cutting tools at the same time had to rely on a large number of imports.

Cutting tools sales of 14.5 billion yuan in China, accounts for less than 25% of carbide cutting tools, cutting tools with the international molybdenum plating structure not only, also can't meet the growing demand of domestic manufacturing of carbide cutting tools. With an annual output of 80000 tons of high-speed steel of our country, accounts for about 40% of global production, consumes a lot of tungsten, molybdenum and other precious rare resources. This blind expansion and low level repetition, making a large sandblasted tungsten target of high speed steel cutter, have to sell at a low price, resulting in a large number of cutting tools production enterprise efficiency is low. Imbalance in the structure of cutting tool is the production of cutting tools and the demand is not right. Carbide cutting tools to meet the needs of users, for example, gap is very big, but high speed steel cutting tools production surplus; Modern manufacturing industries are in urgent need of efficient cutter gap is very big, but low standard tool overproduction.

With an annual output of 16000 tons of cemented carbide in our country, the writer also accounts for some 40% of the total world output. However, carbide products of the highest added value of cutting blades in yield was more than 3000 tons, only 20%. This kind of situation, on the one hand, caused the domestic need of carbide cutting tools are in short supply, on the other hand also make valuable carbide underused resources.

Compared from the aspects of economic benefit, carbide annual sales income of about $560 million in China; Japan is only 40% of our production, but the sales revenue as much as $2.633 billion, including the blade (knife) is as high as 72%, the proportion of the resources were fully used, the enterprise has gained good benefits. Tool industry in China should get some beneficial enlightenment.
