At present, with the 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. 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. 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).

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%.

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.

In recent years, the various areas of high-end manufacturing technology development of our country brings new requirement to tools. If the auto tool must has the characteristics of high efficiency, high stability and specialty, and with the continuous development of auto industry, the new requirement arises at the historic moment, from a technical point of view, there are mainly ChongZaiHua, points out, the trend of specialization, standardization, high speed, and species diversity. In the field of aerospace manufacturing, difficult-to-machine materials such as titanium alloy, high temperature alloys are widely used, how to choose correctly, reasonable use high-quality cutting tool efficiently has become an important topic of industry.

Domestic tool this shall be provided for the manufacturing services have the advantage of, geographical and human conditions. But in fact, the import tool basically dominated the machining industry high-end users, especially in the automotive engine manufacturing workshop, machining workshop, or steam turbine aircraft engine manufacturing enterprises manufacturing workshop, high efficiency, high precision machining of cutting tool in almost monopolized by import tool, it is difficult to see domestic tool. But most domestic tool used in middle and low requirements of customers, such as agricultural machinery, motorcycles, agricultural vehicles, general machinery and the medium of machinery manufacturing industry. Moreover, manufacturing in vulgar development lead to the uneven development of machine tools and cutting tools, according to the international mold association secretary general luo hui is introduced, the developed countries of nc machine tools and cutting tools at present consumption ratio of 2:1, and domestic ratio is too low, the cutting tool consumption amount is less than 1/5 of the total consumption of machine tool. Many manufacturing companies pay big money to buy the machine, but timid on tool consumption, reluctant to buy advanced efficient cutting tools, the traditional tool of long-term high demand market, it is also a lot of domestic enterprises are reluctant to enter advanced efficient production of tools.
