In developed countries, at present, the carbide cutting tools has dominant position of the 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 and cubic boron nitride etc. The proportion of superhard cutting tool is approximately 3%.
Domestic hardware manufacturing consumption of cutting tools, carbide cutting tools has reached more than 50%, the proportion of supply and demand structure disjointed problem is very serious. The consequences are a large surplus of HSS cutting tools export at a low price or sale in domestic market, at the same time efficient carbide cutting tools have to rely on a large number of imports, imports have increased from $2001 in 090 million to $2005 in 450 million (3.6 billion yuan). According to the international mold association secretary general luo hui research, China's current year tool sales of 14.5 billion yuan, accounts for less than 25% of carbide cutting tools, cutting tools with the international market product structure, not only can't satisfy the domestic manufacturing industry growing demand for carbide cutting tools.
China's current annual output of 80000 tons of high-speed steel, accounts for about 40% of global production, consumes a lot of valuable tungsten, molybdenum and other rare resources. This kind of blind expansion and low level repeated, making the production a large surplus of high speed steel tools, have to sell at a low price, resulting in a large number of cutting tools production enterprise efficiency is low.
With an annual output of 16000 tons of cemented carbide in our country at present, about 40% of global production. However, carbide products of the highest value of cutting blades in yield was more than 3000 tons, only 20%. This kind of condition, on the one hand, caused the domestic need of carbide cutting tools are in short supply, on the other hand also make valuable cemented carbide is not fully utilization of resources.
From the aspects of economic benefit comparison, carbide annual sales income of about $560 million in our country; Japan is only 40% of our production, but the sales revenue as much as $2.633 billion, including the proportion of the blade (knife) is as high as 72%, by making full use of resources, enterprises are also good benefits are obtained. Tool industry in China should get some beneficial enlightenment.
Currently: 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, the gap is very big, but high speed steel cutter production surplus; Modern manufacturing industries in urgent need of efficient tools gap is very big, but low standard tool overproduction.
