在立式铣床上加工键槽或径向孔时,需要把工件的中心线对正铣床主轴的旋转中心线,一般的找正方法是用千分表打工件的两侧母线,使偏差最小。这种找正方法不够准确。为了便于找正,我们制作了铣床对刀器(图1)。使用对刀器找正很方便,既提高了找正效率,又 When machining a keyway or a radial hole in a vertical milling machine, the center line of the workpiece needs to be aligned with the rotation centerline of the spindle of the milling machine. Generally, a correct method is to dial the two sides of the work piece with a dial gauge to minimize the deviation. This alignment method is not accurate enough. In order to facilitate the correct, we have made a milling machine tool (Figure 1). Use knife alignment is very convenient, not only improve the efficiency of finding, and
