本文以渐开线修缘直齿、斜齿轮为对象,讨论CBN成形磨齿法中所用单层电镀立方氮化硼(CBN)成形磨轮基体的设计方法与数学模型。根据该方法所设计制造的CBN成形磨轮用于生产实践中,其磨齿精度可达JB179—83 5级精度。一、概述成形磨齿法不仅能提高磨齿效率,简化机床结构、降低加工成本,并可实现对一些特殊齿轮(如内齿轮、大型齿轮、空刀槽较小的双联齿轮)的碎硬后精加工。CBN成形磨齿系采用超硬磨料立方氮化硼,单 In this paper, the design method and mathematical model of single-layer electroplated cubic boron nitride (CBN) forming grinding wheel used in CBN forming grinding method are discussed. According to the method designed and manufactured CBN forming grinding wheel used in the production practice, the grinding accuracy up to JB179-83 Level 5 accuracy. I. Introduction Grinding method not only can improve the grinding efficiency, simplify the machine structure, reduce the processing costs, and can achieve some special gear (such as internal gear, large gear, empty Slot smaller double gear) After finishing. CBN forming grinding tooth system using superhard abrasive cubic boron nitride, single
