近年來，鐵路運(yùn)輸?shù)牟粩嘀剌d提速對鐵路貨車零部件的質(zhì)量提出了更高的要求，特別是轉(zhuǎn)向架的重要組成部件輪軸的機(jī)械性能的好壞和疲勞壽命對車輛運(yùn)行的安全性將產(chǎn)生很大的影響.而車軸的成型磨削是車軸冷加工的***一道工序，其加工工藝的優(yōu)劣更直接影響到車軸的機(jī)械性能和疲勞壽命，所以車軸成型磨砂輪的選擇尤為重要.

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.

車軸成型磨砂輪主要用于RD2型車軸, RE2B型車軸, RD3A型車軸, RD3A1型車軸. 磨削精度好, 在Ra0.6以內(nèi).磨削效率高, 5分鐘之內(nèi)磨削完畢.
