毛毡垫圈的加工,过去通常是采用冲压加工,但对于厚度太大的毡圈冲压加工后往往会出现变形,表面拉毛、锥度大等不良现象,若采用如图所示的刀具,对毡圈进行钻鍯加工,就能克服上述缺点。这种工艺方法简单,操作方便,在普通的钻床上均能进行。加工前,将刀具体2柄部装夹在钻床上,开动钻床,让钻鍃刀高速旋转,手压钻床手柄,对毛毡进行钻鍯加工。鍯成后,钻床手柄上抬,手持轻型轴承6
Felt washer processing, stamping process is usually used in the past, but for the thickness of the felt ring is often deformed after stamping, surface hair, taper and other undesirable phenomena, if the use of the tool shown in the figure, the felt ring Drill 鍯 processing, we can overcome the above shortcomings. This method is simple, easy to operate, can be carried out in ordinary drilling. Before processing, the handle 2 is clamped on the drilling machine, the drilling machine is started, the drilling machine is rotated at a high speed, the handle of the drilling machine is pressed by hand, and the felt is processed and processed.鍯 Cheng, drill handle lift, hand-held light bearings 6
