随着我国精密机械工业的高速度发展,对精密轴承的需要愈来愈迫切。因此急需提供能加工各种规格的精密轴承的专用磨床,并相应的改进工艺装备,以保证加工质量。我厂自行设计制造的切入式滚珠轴承河道磨床,试车时发现夹具定心精度不高,加工小型轴承有困难,必须设法解决。 内孔直径 With the rapid development of China’s precision machinery industry, the need for precision bearings is becoming more and more urgent. Therefore, the urgent need to provide a variety of precision machining can handle a special grinder, and the corresponding improvement of technology and equipment to ensure processing quality. I plant design and manufacture of the cut-in ball bearing river grinder, test fixture found that the fixture centering accuracy is not high, the processing of small bearings have difficulty, we must try to solve.
