China's lack of efficient tools urgent situation changed – Tools, Metal Cutting – Machine Tool Industry
In the "2009 Automotive and Equipment Manufacturing industry development forum", the China Machinery Industry Metal Cutting Xing Min Tool Technology Association said such a ratio: "the domestic import of 7.5 billion U.S. dollars, 24% of high-end machine tools used in the automotive and engine industry. After the adoption of these high-end equipment, 70% of the failures have occurred in the tool , Flexible Fixture side. "
Why? "Currently we are high-speed machine tools, high-quality, high transfer and complex class of machine tools, take a good horse with a good saddle, but now high-quality low profile enterprises in tool with a very serious phenomenon. Tool is the last phase of the process, problem-solving tool , and machine utilization problems will be solved the most. "Xing Min said.
Insiders pointed out that China's manufacturing industry and efficient tool application level is still low, increase productivity potential. Current NC Tool And Measuring instruments Behind the development of CNC machine tools Development, has become an obstacle to our CNC cutting technology and CNC cutting machine development bottleneck, change the status quo without delay.
Advanced market weakness Into the new century, with large-scale manufacturing industries in developed countries shift to China, the domestic manufacturing sector also accelerated the pace of technological transformation, was made in large quantities into the CNC machine tool manufacturing. Following this, a sharp contradiction quickly emerged from the water: advanced CNC machine tools, cutting tools made with less advanced, have to with "foreign knife." After years of efforts made effective tool, has begun to enter the field, but share less than 20%. For example, in 2008, tool consumption in China amounted to 29 billion yuan (about 4 billion U.S. dollars), of which the import tool to reach 10 billion yuan (about 1.4 billion U.S. dollars), the market share of more than 1 / 3. Especially in the 21st century, the import tool spending more than 30% annual growth, exceeding the average growth rate of domestic knives. Domestic market by importing high-end tool in the tool advancing step by step, mainly because of domestic tool in the product structure and quality gap with the developed countries much.

Xie Hua Kun that the "Eleventh Five-Year" during the manufacture of national development priorities of China's major projects include the energy, automotive, aerospace and transportation and other important areas related to people's livelihood, and these major equipment Manufacturing industries typically involved, the key parts of the following characteristics: large, heavy, complex, sophisticated and difficult process in which new materials (such as aluminum alloy, titanium alloy, high strength heat-resistant steel, carbon fiber and composite materials, etc.) Cutting accounted for a large proportion. "This is a CNC cutting technology and CNC cutting machine tools and equipment raised new issues, but also on the cutting tool and digital measurement technology and Measuring Meter put new demands and challenges, providing new opportunities for development and the stage." Hua-Kun Xie said .
Highlights the gap between technical content
"Through research, we felt the tool industry in the technological level and production scale, rapid development and progress, but also to see with foreign advanced level remains high." Participated in by the China Machine Tool Industry Association organized on key national equipment manufacturing industry and tool manufacturing business, after investigation, Kun Xie, feeling deep. He pointed out that wind power, nuclear power and other energy equipment manufacturing industry, the key components used in CNC cutting tools and measuring instruments, almost entirely monopolized by foreign products. Tool is mainly used for domestic and non-critical parts of rough, semi-finishing operations. Compared with foreign products, in addition to a wide gap between cutting indicators, the bigger problem is the quality of unstable and unreliable, a large dispersion of product performance.
Metal cutting tools in China Machinery Industry Technology Association, a responsible person that the Chinese enterprises are facing major problems cutting tool technology first, low-tech. This stage, the carbide cutting tools in developed countries account for the dominant position of the tool type, the proportion of 70%. The proportion of high-speed steel cutting tools are now down to 30%. Currently our annual sales of about 145 tools billion, of which the share of carbide cutting tools less than 25%, but our tool enterprises are blind, to produce a large number of high-speed steel cutting tools, and some low-grade standard tools, to have a high added value, high-tech market in the high-end tool hand over foreign enterprises.
