半盲孔及盲孔液压缸内壁无划痕光整加工技术研究

Research on Inner Wall Smoothly Machining Technology to Hydraulic Cylinder with Blind and Semi-blind Hole

针对典型半盲孔及盲孔液压缸内壁切削光整加工划痕难以避免问题,通过分析减材加工切削光整加工技术的不足,采取粗磨或精镗加精车建立光整加工基准、超声滚压光整强化加工缸筒内壁等工艺措施,实现了半盲孔及盲孔液压缸构件内壁的无划痕光整加工,对机械构件半盲孔及盲孔内壁的无划痕光整加工起到了指导及借鉴作用。

Aiming at disadvantages of common machining technology and going through process analysis,it can be achieved to reach effective machining by ways of founding smoothly machining standard by roughly grinding or rightly boring and turning,strengthening tube inner wall smoothly machining with ultrasonic rolling and so on.It plays a guiding role to stable machining for the mechanical part inner hole as hydraulic cylinder with blind and semi-blind hole.
