opt cutter Tool companies should transform advanced cutting tools

Tool companies should transform advanced cutting tools In recent years, although the number of high-speed and high-efficiency CNC machine manufacturers and products has increased, but with the economic development, the market still needs a large number of efficient and advanced cutting tools. Modern, efficient and advanced cutting tools will gradually become the mainstream of the market.
During the manufacturing process, some advanced machinery manufacturers asked the tool factory for the supply of certain efficient cutting tools and efficient special tools. However, due to the lack of mental preparation and technical preparation of the tool factory, they could not meet such requirements and thus lost. Source. Luo Baihui, a market analysis expert, said that with the development of the economy, the development trend of machine tools should shift to producing high-speed, high-precision, and high-quality products. The high-speed operation requires higher surface treatment requirements for molds, cutting tools, and mechanical parts. Extending the useful life, reducing production costs, and creating higher profits are the common goals pursued by the industry.
In order to cope with high-speed machining and save a lot of processing time and costs, tool improvement has become an important factor. Tungsten Carbide Tools have a growing share in the tool market because of their higher wear resistance and hardness. In order to obtain the best benefits in processing, proper surface treatment must be selected. Medium and heavy load molds must be CVD high-temperature titanium plating, supplemented by precision vacuum heat treatment to achieve acceptable deformation. This part is commonly used in cold forging die, hydraulic drawing die, tungsten carbide drawing line, suction pipe. In the application of tools, molds, and mechanical parts with medium or low load or precise requirements, PVD titanium plating at low temperature (150°C to 500°C) is appropriate. Aluminium titanium nitride with high aluminum content can easily generate aluminum oxide on the surface of the hard film. This layer of oxide film can make titanium aluminum nitride ceramic hard film oxidation temperature reached 923 degrees Celsius, can protect tungsten carbide cutting tool high-speed cutting edge oxidation resistance and maintain high temperature hardness. However, although titanium nitride and titanium carbonitride also form titania oxide films at high temperatures, they are not easily adhered to the hard films and flaking off with chips, which results in a lack of protection of the hard films, rapid oxidation, and deterioration. Therefore, no matter whether the surface treatment of high-temperature or low-temperature coating has to be properly selected, a proper substrate and stable heat treatment must be used, and the pre-treatment of fine-grinding and polishing of the surface must be followed in order to improve. Ultra-high temperature resin bond diamond grinding wheel processing efficiency is lower than METROX grinding wheel, due to the high bonding strength of the grinding wheel, the production cycle is short, the processing cost is low, especially when grinding tool edge is not easy to cause chipping, and according to the use requirements, Grinding into a variety of shape and shape of the molding wheel, so it is still widely used in production for a long time. How to further improve the grinding performance of such grinding wheels has also become an important task at present.
With the rapid development of tool design, manufacturing and use technologies, and the ever-increasing output of cutting tools, ultra-high temperature resin-bonded diamond grinding wheels still cannot fully meet the requirements for high-volume production of cutting tools. There is still room for further development in the number and quality of tools. . The test results show that the improved grinding wheel grinding efficiency can be increased by about 20% on the original basis, and the grinding wheel life can be increased by about 50%.
At present, China's tool production structure and market need to be seriously out of balance. Luo Baihui said that the market needs a large gap in cemented carbide tools, but now the market is mostly high-speed steel tools and low-grade standard tools. Compared with foreign countries, the tool market in China is obviously unbalanced. Manufacturers should adjust tool product transformation as soon as possible and develop high-end, advanced tools.
