拉削在金属切削中是高生产率和高精度的加工方法之一,它能加工许多形状的通孔和外表面,因此在现代机器制造业中,特别在汽车、拖拉机和机床制造厂里更广泛的采用了拉削工艺。 本文介绍几种简易实用的拉刀卡头,供工厂参考使用。 图1所示为小孔拉刀用卡头。由于拉刀本身已经很小( Broaching is one of the most productive and accurate machining methods in metal cutting. It can process many shapes of through-holes and external surfaces and is therefore more widely used in modern machine building, particularly in the automotive, tractor and machine tool manufacturing industries The use of broaching process. This article describes several simple and practical broach chuck for factory reference. Figure 1 shows a small hole broach chuck. As the broach itself has been very small
