这是一个切削法兰盘两端面,和同时进行倒圆角的自动退刀刀架。它不但能保证不碰伤切削表面,同时也能缩短加工时间。 刀架是由三个基体组成,如图中1、2、3所示。基体1、2上装有夹刀用的夹头4、5,夹头能绕轴6转动。 夹头和基体间装有弹簧7。在吃刀的时候,由於切削抗力的作用,左刀 This is a cutting flange both ends, and at the same time round the automatic retractor knife. Not only does it guarantee that it does not scratch the cutting surface, it also shortens the machining time. Tool holder is composed of three substrates, as shown in Figure 1,2,3. The base body 1 and 2 are provided with clamps 4 and 5 for clamping blades, and the clamps can rotate around the shaft 6. There is a spring 7 between the collet and the base. When eating a knife, due to the role of cutting resistance, the left knife
