Hard alloy tool industry represent the general trend of development

From the status quo of China's tool industry's point of view, on the one hand, it has made important contributions to the development of China's manufacturing industry; but on the other hand, compared with the manufacturing industry in the "Twelfth Five Year Plan" period demand, its transformation three aspects still exists a gap in the product structure adjustment, the tool innovation and industry. "Twelfth Five Year Plan" period, we have made new progress in these three areas, in order to meet the demand "Twelfth Five Year" development planning of tool industry, and lay the foundation for further development.

Firstly, a product structure adjustment. Now, tool material has already entered into the hard alloy dominated era, compared with the high speed steel, hard alloy has better performance and higher cutting efficiency, and super hard tool materials together, is the guarantee for realizing high efficiency machining of the most important modern cutting technology. At present, our country hard alloy cutter accounted for about 40%, far below the level of developed industrial countries, the overall level of our tool products to improve. No good tool materials, any tool innovation and cutting technology progress are the lack of the necessary material foundation, can only be castles in the air. However, in order to fundamentally solve this problem, relates to the industry structure adjustment. In addition to Zhuzhou diamond cutting tool Limited by Share Ltd existing, must accelerate with hard alloy material and tool research and development capacity of the production base construction process, rapid increase of cemented carbide cutting tools account for the proportion of all tool. This is a great investment project, need to relevant government departments to guide and support.

Secondly, attention must be paid to tool innovation. The cutting tool innovation is to promote technological progress and improve the machining efficiency is the most important factor. Modern tool innovation performance in three aspects:

First, the innovation of steel. It accounted for a large proportion in the tool innovation present in. Comprehensive foreign companies with hard alloy and super hard material development and production capacity, will launch a large number of tool material new year, become the main selling point of the new product they tool. The development train of thought is, according to the characteristics and requirements of application, integrated materials, coatings and channel advantages, "an antidote against the disease" development, make the blade has a performance advantage in the application within a certain range, get the processing effect is good, can generally make the machining efficiency is improved by more than 20%. Therefore, to speed up the construction of China's Cemented Carbide Tool Materials R & D and production base be imperative.

Second, innovation of cutting tool coating. Since the coating technology into the application fields, development of cutting tool coating technology very quickly. Along with the development of coating technology, equipment, components of innovation development continues to accelerate, the tool modification has been enhanced. Because of the characteristics of coating technology can improve the cutting performance effect, process flexibility is good, new brand development quickly, not only makes the tool cutting performance has been greatly improved and improved, but also the innovation of blade coating grade well and quickly. The coating has become the most important factor in cutting technology. So far, the ability of independent development of our country still does not have the equipment and process of cutting tool coating, restricts the innovation progress cutting technology in our country and the coating grade. Therefore, vigorously develop the tool coating technology is a pressing matter of the moment.

Third, innovation tool structure. At present, the tool structure innovation momentum is very strong, showing great potential. In recent years the machine tool exhibition, new kinds of tool cutting tool manufacturers compete to launch the attention spot. The tool structure innovation not only improves the performance of tools, has a great influence on the development of some type of tool. For example, the milling cutter can be realized structure slope milling cutter, greatly expanding the function, reducing tool change time, its structure has been applied to different types of milling cutter, the cutter milling for various slope, promoted the development of milling and milling cutter. In addition, such as the new tool structure small depth of cut, feed mill with spiral angle of vibration mill, wiper blade, blade car bottom rails with tool and profiling tool, tool cooling structure emerge in an endless stream, be too numerous to enumerate. Great concern to appear each new tool would result in industry, and the rapid popularization and application in industry, for the development of cutting tools, improve tool performance plays a great role in promoting. Only do many tool enterprises in our country is not production tool, cutting tool material, so we must pay more attention to the creativity tool structure.
