摘　　要：建立内冷却平面磨削实验系统,研究内冷却磨削的磨削能力。实验表明:采用内冷却磨削可以显著降低磨削区温度,避免磨削烧伤,并且随着切削液流量的增大,砂轮振动会加剧,被加工表面的粗糙度增大,但是在砂轮主轴刚性运动的范围内,振动对表面粗糙度的影响不明显;内冷却磨削的切削液流量更小,大大提高了切削液的利用率。因此,在加工精度要求高、且对磨削烧伤比较敏感的工件时,内冷却磨削是避免磨削烧伤的一种实用、有效的加工方法。An inner cooling plate grinding experiment system is developed to study grind capacity of inner cooling grinding. The experiment shows that the inner cooling grinding can significantly reduce the temperature of grinding area and effectively avoid grinding burn, vibration of grinding wheel is aggravated, surface roughness is increased, but when the spindle have good rigidity, surface roughness isn＇ t increased obviously. In additional, cutting fluid＇ s flow of inner cooling is less than that of external cool- ing, so utilization rate of cutting fluid is greatly improved. In a word, when workpiece is sensitive to grinding burn and require high precision,inner cooling grinding is a practical and effective processing method to avoid grinding burn.
