我厂所生产的产品零件中有许多具有多台阶孔,或者孔精度较高不便车镗。所以我们设计了这种离合器式车库夹头。使用证明它具有刚性好,定位准确,操作方便。工作原理如下: 首先依加工零件选用三件刀具,依加工顺序分别紧固在三个夹头(图中8)上。 Many of our product parts have multi-step holes, or high-precision hole boring inconveniences. So we designed this clutch type garage collet. Proved it has good rigidity, accurate positioning, easy to operate. The working principle is as follows: First of all, according to the processing of parts selected three knives, respectively, according to the order of processing fastened in the three chuck (Figure 8).
