为了降低加工成本,经常采用高效率切削方法。其途径有:(1)高速切削;(2)高速进给;(3)加大切削深度。现以铸铁和钢为被切削材料,以车削和铣削为切削方法,来论述高速切削的现状和发展趋势。 1.高速切削的现状表1是日本1985年车削汽车零件的最高切削速度和1987年要达到的切削速度目标。由该表可知,车削铸铁时,能实现“高速切削”,而切削钢时,尚未达到高速切削范围(高速切削铸铁或钢的切削速度范围在500～5000m/min)。
In order to reduce processing costs, often using high-efficiency cutting method. The ways are: (1) high-speed cutting; (2) high-speed feed; (3) increase the depth of cut. Cast iron and steel are now being cut material, turning and milling for the cutting method to discuss the status of high-speed cutting and development trends. 1. Status of High-Speed Cutting Table 1 shows the maximum cutting speed of turning automotive parts in Japan in 1985 and the cutting speed target to be achieved in 1987. From this table, it can be seen that “high-speed cutting” can be achieved when turning cast iron, and high-speed cutting range has not yet been reached when cutting steel (cutting speed of high-speed cutting cast iron or steel ranges from 500 to 5000 m / min).
