金属高速切削加工法已被广泛地传播开来了。主要的机械制造工厂的高速车工们已经牢固地掌握了在200、300、400公尺/分切削速度下工作的技术。很多车工在高达600、700公尺/分甚至更高的速度下工作。车工贝科夫及布蘇也夫已超过2000公尺分的速度。为了高速加工法今後的发展,以及正碓地使用切削用量,必须更彻底地研究高速下金属的切削区城内所发生的过程。测定在切削区域内所产生的温度,对了解金属切削过程有着特别重要的意义。在本文所载的试验中,切削温度系用大家都知道的自然热电偶来测量(参考书1)。这样测得的是刀具与切屑以及工件相接触处的平均温度。在高速车床上进行了炭鋼及铬鋼的圆环及圆盘、以及有
Metal high-speed machining has been widely spread. High-speed turners at major machinery manufacturing plants have solidly mastered technologies that operate at cutting speeds of 200, 300 and 400 meters per minute. Many car workers work at speeds up to 600,700 meters per minute or more. Machinists Bekov and Bussuyev have more than 2000 meters speed. In order to develop the high-speed machining method in the future and to use the amount of cutting headlong, the process that takes place in the metal cutting zone at high speed must be studied more thoroughly. Measuring the temperature generated in the cutting area is of particular importance for understanding the metal cutting process. In the tests contained in this article, the cutting temperature was measured using a natural thermocouple well known (Ref. 1). This measures the average temperature of the tool in contact with the chip and the workpiece. In the high-speed lathe on the carbon steel and chrome steel rings and discs, and there
