气缸套是空气压缩机和内燃机上的一个重要部件。降低气缸套内表面的粗糙度值,对提高气缸套内表面的耐磨性,延长其使用寿命以及提高整机的工作效率都具有十分重要的意义。目前,生产气缸套的厂家大部分是利用砂布精珩气缸套的方法来降低其表面粗糙度。但使用这种方法,砂布极易磨损和破碎。加工效果不稳定,工人的操作条件很差。因此,急需一种抛光质量好,高效,低成本,使用方便的新工艺方法来满足实际生产的需 Cylinder liners are an important part of air compressors and internal combustion engines. Reducing the roughness value of the inner surface of the cylinder liner is very important for improving the wear resistance of the inner surface of the cylinder liner, prolonging its service life and improving the working efficiency of the complete machine. At present, most of the manufacturers of cylinder liners are using the method of emery cylinder liner to reduce the surface roughness. However, with this method, the emery cloth can easily be worn and broken. The processing effect is not stable, the working conditions of workers are poor. Therefore, there is an urgent need of a new polishing method which is good in polishing quality, high in efficiency, low in cost and convenient in use to satisfy the needs of actual production
