摘　　要：针对目前加工双列四点接触球轴承沟道时存在的加工精度和效率低等问题,提出了采用集中工序和成形刀具加工相结合的加工方法。并以此加工方法为基础,分析目前常见的砂轮修整装置的结构特点,提出改进的设计方法。实践使用证明,该加工方法与改进后的砂轮修整装置的使用能提高双列四点接触球轴承沟道精度至P5甚至达到P4,缩短50%以上的加工时间。Pointed at the problems of the low precision and efficiency during machining the grooves of double row four point contact ball bearings, a method is put forward, which integrates both concentrative process and machining with forming tools. Based on this method, a familiar grinding wheel dresser is well researched and analyze, and a late - model one is designed. The practice revealed that this device, based on the advanced method above, have high precision, up to P4 level, and high efficiency, about 50% time is reduced.
