中大型深沟球轴承外圈沟道精仿工艺

摘要

仿形车床C7232原来用于中型深沟球轴承外圈沟道的粗加工，精加工由成型车刀完成。由于产品转型，加工直径变为φ250mm~φ320mm之间，沟道变宽使切削力增加，精车工序无法由成型刀完成。针对以上问题，用C7232车床进行精车试验，圆满完成中大型产品外沟道精加工，质量符合要求%　　Profiling lathe C7232 is formerly used for rough machining of outer ring groove of medium deep groove ball bearing, finish machining is performed by forming tool. Because the processing diameter changed to 250mm-320mm, that makes groove wider and cutting force increase, finish turning cannot be completed by forming tool. For solving above problem, finish turning test has been performed by C7232, the test result show that C7232 is suitable for finish turning of outer ring groove of medium and large product and the product quality conforms to requirements.
