我厂在生产柱塞高压油泵主轴时,端面有8个半球窝孔。技术要求为:1.球窝公差为φ27~(+0.035);球窝圆度小于0.005;3.球窝光洁度不低于10。过去是利用展成法单刀加工,加工时比较麻烦,加工效率又低,8个球窝深浅大小难以达到一致,而且还要进行研磨、配磨。油泵主轴的材料为38CrMoAl,加工时也很费刀具。经过分析,由于此轴为半球窝孔,如毛光刀余量和光浩度控制得
I plant in the production of high-pressure piston pump spindle, the face has eight hemispherical hole. Technical requirements: 1. Ball tolerance for φ27 ~ (+0.035); ball roundness less than 0.005; 3. ball and ball finish of not less than 10. The past is the use of development law single-pole processing, processing more trouble, processing efficiency is low, the size of the eight ball and socket difficult to achieve the same size, but also for grinding, with grinding. Pump spindle material 38CrMoAl, processing is also very expensive tool. After analysis, because this axis is a hemisphere socket hole, such as wool knife margin and Guanghao control
