我厂加工液压操纵阀阀杆的节流槽,过去采用成形立铣刀铣削加工,铣削后由于槽底不尖,还要用车刀拉削使之成形,因此加工时间较长。后来,在群众性的技术革新中,工人师傅想办法改进了工艺,采用飞刀铣削(如图1所示),将刀具装在工具铣卧铣头上,转速为 1200转/分,工件先用具有偏心 e的 I plant machining valve stem throttle throttles, the past, the use of forming milling cutter milling, milling after the end of the groove is not pointed, but also with the turning tool to make it forming, so a longer processing time. Later, in the masses of technological innovation, the workers master to find ways to improve the process, the use of flying knife milling (Figure 1), the tool mounted on the milling tool milling head speed of 1200 rev / min, the workpiece first With eccentric e
