钢制实体保持架兜孔加工工艺改进

Improvement on Processing Technology of Steel Solid Cage Pocket

针对40CrNiMoA钢制实体保持架原兜孔加工中,由于保持架材料硬度高、黏性大,容易出现兜孔表面粗糙度大,甚至出现划伤的问题,改进原铣削加工为镗削通孔,采用硬质合金刀片,通过加工试验对比,验证了改进后工艺的有效性。

For the original processing of 40CrNiMoA steel solid cage pocket, there are problems such as rough pocket surface or even scratches due to the high hardness and high viscosity of the cage material, To improve processing quality, the original milling is replaced by boring through hole, using Carbide blade. The comparison of processing experiments verifies the effectiveness of the improved process.
