In the field of automobile transmission housing processing, high-speed machining centers, high-strength tool holders and high-efficiency tools are widely used in foreign countries for processing. Except for manual loading and unloading, the rest are basically automated processing. In China, the machining centers produced in the 1980s and 1990s are generally used. The handles and knives continue the old habits, and the processing efficiency is basically 50% of foreign countries. Even if an efficient tool is purchased, the expected result is not achieved due to the aging of the machine. Therefore, it is especially important to promote high-speed processing technology in China.
High speed machining is a comprehensive technology. Satisfactory results are required to achieve synergistic cooperation between high-speed machine tools, good CNC systems, CAD/CAM, suitable tools and optimized machining processes.
The origins of high-speed machining technology can be traced back to 1931, during which time there was a patent describing the high-speed machining process. Since then, about 30 years later, people have learned about the cutting process and working principle of high-speed cutting. However, high-speed cutting is really on track only after the development of efficient machine tool accessories (such as high-speed motor spindles, high-quality tooling and high-quality surface coating technology and corresponding fixtures).
According to the definition of the 1992 International Conference on Production Engineering (CIRP) Annual Meeting, high-speed cutting (HSC) refers to cutting that cuts more than 5-10 times the cutting speed. Therefore, depending on the material and the processing method, the cutting speed range of high-speed cutting is also different. High-speed cutting includes high-speed milling, high-speed turning, high-speed drilling, high-speed turning and milling, etc., but most of them are high-speed milling. At present, the processed aluminum alloy has reached 2000-7500 m/min; the cast iron is 900-5000 m/min; the steel is 600-3000 m/min.
