2012 carbide cutting tools in China development situation analysis

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 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, imports has risen from $2001 in 090 million to $2005 in 450 million (3.6 billion yuan). International mold association secretary general luo hui said, 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.

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%.

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.

International mold association secretary general luo hundred hui pointed out that China should focus on efficient high quality cutting tools market. In recent years, our country various areas of high-end manufacturing and technology development brings new requirements 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, new requirements arises at the historic moment, from a technical point of view, the main 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 alloy is widely used, how to choose correctly, reasonable use cutting tools for high quality machining has become a very important industry.

Domestic tool this shall be provided for theMolybdenum cruciblehave 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 plant, high efficiency, high precision almost monopolized by imported cutting tools in the machining of cutting 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 the mechanical 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 numerical control machine tools and cutting tools in the developed countries abroad consumption ratio is 2:1, and domestic proportion is too low, cutting tool consumption amount is less than 1/5 of the total consumption of machine tool. Many manufacturing companies pay big money to buy 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 the domestic many enterprises are reluctant to enter the advanced and efficient production of tools of the important reasons.
