直径小于0.55mm的弹簧夹头,夹头体内装夹刀具的小孔是很难加工的,常常因不同心度超差而造成废品。我厂工具车间将夹头内装夹刀具的小孔部分改革成在夹头体内镶三瓣卡爪,克服了不易加工的困难。镶片式弹簧夹头如图1,三瓣卡爪在夹头体内按图1中K向视图分布。每瓣卡爪是吸在导磁性的夹具上分别加工的(如图2)。先磨卡爪120度的二侧作基
Collet chuck with diameter less than 0.55mm is very difficult to process. It is often difficult to process the small holes in the chuck body because of poor tolerance. I plant tools workshop will be chucking the hole within the tool part of the reform into the body in the chuck set three claws, to overcome the difficult processing difficulties. Inlay collet chuck as shown in Figure 1, three claw claws in the collet body according to Figure 1 K to view distribution. Each flap claw is sucked in the magnetic fixture were processed (Figure 2). First grinding claws 120 degrees on both sides of the base
