Briefly describe the development of high efficiency processing technology
Professor Philipp Andrae of the University of Hanover and his research team overcame the problems of high-speed cutting technology and developed new technologies for high-efficiency machining. At the beginning of the study, it was emphasized that the quality and production efficiency of the machined parts in the cutting process were greatly improved. Inheriting the high-speed cutting can reduce the cutting force, improve the precision of the machined parts and the surface quality. From the purpose of improving production efficiency (improving the resection rate in roughing), a large number of cutting tests are carried out. The combination of theory and practice has solved many technical problems and made great progress in the development and research of high-efficiency cutting technology. The key to high-efficiency machining technology is to select or redesign high-power, high-rigidity machine tools with sufficient spindle speed and high torque to perform high-power cutting according to the newly developed high-efficiency cutting theory; Advanced tool materials such as: hard alloy (coated and uncoated), cermet, ceramic, polycrystalline diamond (PCD) and polycrystalline cubic boron nitride (PCBN); tool geometry is optimized by computer The geometry is matched with the tool chuck suitable for high-speed and high-efficiency cutting, and must be balanced with high precision before use. Select reasonable cutting parameters, especially according to the cutting conditions of the material to be machined. Medium cutting speed, etc.; Advanced tool chucks such as hydraulic collapsible chucks and heat-shrinkable collet chucks suitable for high-speed, high-power cutting; and special technical methods such as special processing methods. For example, in a high-power horizontal machining center, a multi-edge composite hole machining tool (bit and reamer) made of polycrystalline diamond (PCD) or coated diamond is used to machine high-precision bores; to improve production efficiency, Reduce production costs, use machine-clamped multi-blade polycrystalline cubic boron nitride (PCBN) end mills for high-precision inner hole machining (by program control to carry out roughing, finishing, adjustment of inner hole size processing); The blade-coated carbide roughing cutter has achieved good processing results for large-scale, high-power milling and other special processing solutions. At present, the research results can only be used for aerospace aluminum alloy parts that require high-volume, high-efficiency processing. However, because it can improve the market competitiveness of manufacturing enterprises and has a good market prospect, it will inevitably develop rapidly.
