摘　　要：活塞式无油润滑压缩机的钩形填料密封环常规加工工艺,存在填料密封环加工精度低及材料利用率偏低的缺点。对钩形填料密封环的铣加工工序进行改进,提出优化的钩形填料密封环加工工艺,从而提高了填料密封环的加工精度,密封环漏气量明显减少,能够更好地满足活塞式无油润滑压缩机的使用要求。Aimed at the shortcomings of conventional machining technics of hooked packing ring for oil free piston com-pressor, such as low precision in packing ring and low usage rate of material, the machining procedures ot milling were improved for the hooked packing ring and its optimal machining technics was proposed, thereby the machining precision of hooked packing ring was increased, air leakage rate of the packing ring was decreased, so application requirement for oil free piston compressor can be fulfilled even better.
