人们很早就重视提高砂轮圆周速度带来的效益，并在试验及研究的基础上迅速发展了高速磨削技术。60年代初砂轮圆周速度由33m／s很高至45～63m／s，至70年代初又达到80～90m／s。但由于工件受热变形和表面烧伤及砂轮强度、机床等方面因素限制，高速磨创技术曾一度发展缓慢。自80 People paid great attention to improving the peripheral speed of grinding wheel, and developed the high-speed grinding technology rapidly on the basis of experiment and research. In the early 1960s, the peripheral speed of the grinding wheel was high from 33m / s to 45 ~ 63m / s and reached 80 ~ 90m / s in the early 1970s. However, due to the deformation of the workpiece by the heat and the surface burns and wheel strength, machine tools and other factors, high-speed grinding technology was slow to develop. Since 80
