我厂在加工内弧形模具(图1)时,过去一直是先钻毛坯孔,然后用成型铰刀粗铰、半粗铰、半精铰、精铰来完成的。铰刀是相当复杂的刀具,制作比较困难(图2):车毛坯、铣、钳、淬火、外磨两端直径至要求、曲线磨床磨弧形。几道工序下来,合格的铰刀仅为80%左右,回到车工工序、油石修、研磨、上车床调试,非常麻烦。

I plant processing within the arc mold (Figure 1), the past has been the first drilling rough hole, and then use the reaming knuckle hinge, semi-coarse hinge, semi-fine hinge, fine hinge to complete. Reamer is a very complex tool, making it more difficult (Figure 2): car rough, milling, pliers, quenching, diameter grinding at both ends to the request, the curve grinder grinding arc. A few procedures down, qualified reamers only about 80%, back to the turndown process, stone repair, grinding, lathe debugging, very troublesome.
