New cutting processes such as hard cutting and dry cutting, which are represented by high-speed cutting, have shown many advantages and strong vitality. This is the requirement of manufacturing technology to improve machining efficiency and quality, reduce costs, and shorten development cycle.
Therefore, the development of new cutting processes such as high-speed cutting and the promotion of manufacturing technology are the most prominent features of modern cutting technology development. Contemporary high-speed cutting is not only an increase in cutting speed, but a need for comprehensive advancement in manufacturing technology and further innovation (including significant advances in CNC machine tools, tool materials, coatings, tool structures, etc.) to achieve cutting speeds and feed rates. The multiplication of the multiplication and the transformation and innovation of the traditional cutting process have led to a significant improvement in the overall cutting efficiency of the manufacturing industry.
Hard cutting is an application field of high-speed cutting technology, which uses single- or multi-blade tools to process hardened parts. Compared with traditional grinding, it has the advantages of high efficiency, good flexibility, simple process and low investment. Produce better results in some application areas.
In the automotive industry, the use of high-speed cutting technology to process 20CrMo5 hardened gear (60RHC) bore, instead of grinding, has become a new process promoted by the domestic and international automotive industry. High-speed precision milling of hardened steel molds in the mold industry with high-speed cutting technology, taking a small stepping distance, without the knife in the middle, finishing the finishing of the profile, greatly reducing the amount of polishing work, significantly shortening the development cycle of the mold Has become a new process in the mold manufacturing industry. In the machine tool industry, CBN cyclone milling ball screws are used instead of thread grinding, and hard alloy hobs are used to process hardened gears, which show strong vitality.
Another new process derived from high-speed cutting is dry cutting. The environmental pollution caused by the cutting fluid in the cutting process and the damage to the operator's health have become the focus of current governance, but the treatment of the damage caused by the cutting fluid increases the manufacturing cost, leading to the development of new dry cutting technology, and has emerged. New technology for quasi-dry cutting such as micro-lubrication cutting and cold-air cutting.
The current dry cutting is not simply removing the cutting fluid from the original process, reducing the cutting efficiency, but making a major revolution in the traditional cutting process, providing a clean, safe and efficient new process for the new century. Comprehensive challenges to cutting technology including tool materials, coatings, and structures. The consumption of precious metal resources for tool materials and the development of new technologies such as tool re-grinding and recycling have become the responsibility of cutting processing for human civilization and social progress.
