万能外圆磨床的砂轮一工件一机床系统,往往由于振动而使加工工件的表面光洁度只能达到▽▽▽8～▽▽▽9,而且表面有振纹不能满足新产品生产的需要。因此我们对上海机床厂1959年生产的M131W型万能外圆磨床采用了一些提高精度的措施,这样一来,就使磨床磨削的轴类零件光洁度达到▽▽▽▽11,稳定在▽▽▽▽10,不圆度为0.001毫米,收到了预期效果。为达到互相学习和共同提高的目的,现将我
Universal cylindrical grinder grinding wheel workpiece-a machine system, often due to vibration so that the surface finish of the workpiece can only reach ▽ ▽ ▽ 8 ~ ▽ ▽ ▽ 9, and the surface of the vibration can not meet the needs of new product. Therefore, we adopted some measures to improve the precision of the M131W Universal Cylindrical Grinder manufactured by Shanghai Machine Tool Plant in 1959. As a result, the smoothness of the shaft parts grinded by the grinding machine reached ▽ ▽ ▽ ▽ 11 and stabilized at ▽▽ ▽ ▽ 10, out of roundness of 0.001 mm, received the expected results. For the purpose of mutual learning and common improvement, let me now
