陶瓷结合剂砂轮的速度为30～35 m/s；树脂结合剂的砂轮速度为35～50 m/s。当发现表面烧伤时，应将砂轮速度降至16～20 m/s。
工 件速度，当工件直径小于50 mm时，n=120～150 r/min；大于50 mm时，n=40～80 r/min。用砂轮外圆进行平面精磨时，工作台运动速度一般为15～20 m/min，粗磨时为5～50 m/min。磨削深度和横向进给量小时取大值，横向进给量大时取小值。粗磨深度为0.04～0.08 mm，精磨深度为0.01 mm。修整砂轮后应减小磨削深度。
外圆磨削时纵向进给量，粗磨时为(0.2～0.7)B mm/r，精磨时为(0.2～0.3)B mm/r；内圆磨削时纵向进给量，粗磨时为(0.4～0.7)B mm/r，精磨时为(0.25～0.4)B mm/r；砂轮外圆平面磨横向进给量，粗磨时(0.3～0.7)B mm/dst，精磨时为(0.05～0.1)B mm/dst。
