Hard alloy tools for future space tremendous

    Tool material into the hard alloy era innovation from the status quo of China's tool industry's point of view, on the one hand, it has made important contribution to the development of China's manufacturing industry; but on the other hand, compared with the manufacturing industry in the "Twelfth Five-Year Plan" requirements, in the product structure adjustment still exists certain gap in the whole, tool innovation and industry transformation in three aspects.

    "Twelfth Five-Year Plan" period, we have made new progress in these three areas, to meet the requirements of the "Twelfth Five-Year" development planning of tool industry, and lay the foundation for further development. First of all, on the adjustment of product structure.

     Now, cutting tool material has entered the era of hard alloy, compared with the high speed steel, hard alloy has better performance and higher cutting efficiency, it and superhard tool material, is the guarantee of efficient processing 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, restricts 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 capabilities, production base in the construction process, rapid increase of cemented carbide cutting tools account for the proportion of all tool.

    This is a need of large investment projects, to the relevant government departments to guide and support. Secondly, attention must be paid to the problem of tool innovation. The tool of innovation is driving cutting technology progress and improve cutting efficiency of the most important factors.

    Modern tool innovation in three aspects:

    First, the innovation of material. It accounted for a large proportion in the tool innovation. Comprehensive foreign companies with hard alloy and super hard material development and production capacity, will launch a large number of new tool materials each year, has become a major 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 advantage, "an antidote against the disease" development, make the blade has a performance advantage in certain application scope, get the processing effect is good, can generally make the machining efficiency is improved by more than 20%. Therefore, accelerating 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. With the development of coating technology, equipment, components of innovation development continues to accelerate, it on tool modification effect is enhanced. Due to the characteristics of coating technology could improve the cutting performance significantly, 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 a factor in promoting cutting technology is the most important. So far, the ability of independent development in our country does not have the cutting tool coating equipment and technology innovation, restrict the progress of cutting technology in China 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, various new tool structure of tool manufacturers compete to launch the attention spot. Tool structure innovation not only improves the performance of tools, produced very big effect and some even on tool development of varieties. For example, can realize the cutter 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 bottom guide with threading and copying lathe tool, tool cooling structure emerge in an endless stream, be too numerous to enumerate. Great attention of every new tool appearance will cause the industry, and the rapid popularization and application in the industry, to the development of cutting tools, improve tool performance plays a great role in promoting. Just as many of our tool enterprises tool, not the production tool material, so we must pay more attention to the creativity tool structure.
