【摘要】 本文针对现有大型回转体零件精加工困难的现状，对砂带磨削此类零件的加工机理进行了分析探讨，并以３０万干瓦汽轮机转子主轴为例进行试验，证明了砂带磨削是解决这类零件精加工的有效方法．更多还原

【Abstract】 In the light of the present situation of finish machining difficulty to large-size rotarysolid the machanism machined by belt grinding is analysed and studied,and experiments aredone,taking the rotor of a 300,00kW turbine for example,it proves that the belt grinding is aneffective method for the finish machining of this kind of parts.更多还原
