圆锥销的磨削加工,一般在无心磨床上进行。在没有无心磨床时,一般采用两个在一起(中间切槽)加工,磨削后切断的方法。这种方法容易产生弯曲。在磨削时由于工件磨削颤动的现象,磨削效率也较低。现介绍一种用90°三棱顶尖磨削的方法,即把主轴端的顶尖变成三棱锥形(如图),用它来带动工件旋转进行磨削。我们经过几年的实践,证明效果较好,对大端有内螺纹的圆锥销更为适用。 Cone pin grinding, generally carried out in the centerless grinder. In the absence of centerless grinder, the general use of two together (the middle slot) processing, cutting after grinding method. This method is prone to bending. Grinding due to workpiece grinding vibration phenomenon, lower grinding efficiency. Now introduced with a 90 ° triangular top grinding method, that the top of the spindle end into a triangular pyramid (Figure), use it to drive the workpiece to rotate grinding. After several years of practice, we proved that the effect is better, and it is more suitable for the large-end tapered pin with internal thread.
