当套筒零件内孔的加工精度和表面质量要求很高时，内孔在精加工之后还需要进行光整加工。常用的光整加工方法有研磨、珩磨和滚压等。研磨多系手工操作，工人劳动强度较大，通常用于批量不大且直径较小的孔，珩磨工艺其效率较低，而采用滚压工艺可以使精度在 0.01mm以内，表面粗 When the inner part of the sleeve hole machining accuracy and surface quality requirements are high, the hole after finishing still need finishing. Commonly used finishing methods are grinding, honing and rolling. Grinding more than manual operation, workers labor intensity, usually used in small batch and smaller diameter holes, honing process its lower efficiency, and the use of rolling technology can make the accuracy of less than 0.01mm, the surface roughness
