当没有分度头时,如何在铣床上铣削一对相对位置为180°的轴向槽,建议采用如下的简易方法。如图所示,制作一个“按钮形”定位块,其大端直径比加工轴直径略小0.025毫米左右,小端(定位柱)直径与键槽宽度相配。操作时,将加工轴夹持在铣床平口钳里,两端用顶针顶紧,铣第一条键槽,然后只需将轴反向转动180°(不需要重新调整铣
When there is no indexing head, how to mill a pair of axial slots with relative position of 180 ° on the milling machine, the following simple method is suggested. As shown in the figure, a “button-shaped” positioning block is made, the diameter of the large end is slightly smaller than the diameter of the processing axis by about 0.025 mm, and the diameter of the small end (positioning post) is matched with the width of the keyway. During operation, the machining axis is clamped in the milling machine and the two ends of the machining shaft are pressed tightly by the thimble. The first keyway is milled and only the axis is rotated 180 ° in the opposite direction (no need to readjust milling
