概述高速磨削能提高磨削效率、工件表面光洁度和砂轮耐用度,它是当前磨床发展的主要趋向。根据高速磨削的特性即砂轮线速度提高之后,单位时间通过磨削区的磨粒数目成倍增加,在定进给情况下,砂轮与工件的磨擦加剧,使得单位时间内产生的热量也成倍增长。据TRIGGER指出:T=CV~n(式中:T-切削温度,V-切削速度,C,n-在给定条件下是常数)。从此公式看出:随着切削速度的提高,切削温度以速度的n次方增 Overview High-speed grinding can improve the grinding efficiency, surface finish and wheel durability, it is the main trend of the development of the current grinder. According to the characteristics of high-speed grinding wheel speed is improved, the unit time through the grinding zone of the number of abrasive doubled, in the case of a fixed feed, the grinding wheel and workpiece friction intensified, making the heat generated per unit time also become Double the growth. According to TRIGGER: T = CV ~ n (where: T-cutting temperature, V-cutting speed, C, n are constants under given conditions). From this formula, it can be seen that as the cutting speed increases, the cutting temperature increases by the n th power of speed
