摘　　要：油石与工作压力的选用是珩磨加工的关键技术,是保证内孔光整加工顺利进行的重要环节。简述了油石与工作压力在内孔珩磨过程中选用的基本原则,在选用油石磨料、硬度、粒度和工作压力方面进行了分析,并通过实践探索,确定了7A04超硬铝工件的内孔光整加工方案,采用数控加工得到了合格的薄壁细长筒类零件。The selection of the hone and pressure is the key to honing and the prerequisite to finishing inner holes suc- cessfully. This paper deals with the basic principles for applying the proper hone and pressure to honing inner holes. Consid- ering the performances and characteristics of the new material that is honed, which includes the machining difficult point and operating step,and is employed by analyzing such hone material as hardness,grit and cross hatch angle and the pressure. The machining difficult point is that the machined part is of slim and thin-wall cylinder type. By the practise, the processing pro- gram of superduralumin 7A04 in inner bore is ensured, and we get the eligible parts through numerical control machine methods.
