摘　　要：异形燃气涡轮轴承的外环滚道截面形状为波瓣形，精度要求很高。本文采用的微位移进给驱动机构具有高频响、高精度、大行程，且控制简便的特点。在研究陶瓷结合剂ＣＢＮ砂轮修整及磨削工艺的基础上，采用前馈与速度反馈的控制方法，对工件进行了加工。For high speed roller bearings used in aircraft engine,the roller′s slipping is one of the main causes which result in bearing damage.A kind of new roller bearings having non circular inner race is proved to be a valid method to solve the slipping problem.In this paper,a strategy to grinding the trilobed inner race by using linear motor control technique is presented and illustrated.Practical machining experiment has been made and machining results are satisfactory.
