近年来，铁路运输的不断重载提速对铁路货车零部件的质量提出了更高的要求，特别是转向架的重要组成部件轮轴的机械性能的好坏和疲劳寿命对车辆运行的安全性将产生很大的影响.而车轴的成型磨削是车轴冷加工的***一道工序，其加工工艺的优劣更直接影响到车轴的机械性能和疲劳寿命，所以车轴成型磨砂轮的选择尤为重要.

Inrecent years, the continuoushe***y loadspeedincrease of railway transport hasput forwardhigher requirements for the quality of railway freight carparts, especially the mechanicalproperties and

fatigue life of the wheel shaft,animportantcomponent of the bogie, will h***eagreatimpacton thesafetyofvehicleoperation. Theshapegrindingofthe axleis the lastprocessof thecoldprocessing of the axle, and the qualityof theprocessing technology  directly affects themechanical properties and fatiguelife of the axle,so the choice of the shape grinding wheelis particularly important.
