我厂进口的轴承磨床上装有砂轮动平衡装置，它对刚换上的砂轮进行动平衡。我们对砂轮进行动平衡加工出的工件与只进行静平衡加工出的工件进行比较，结果表明：经过动平衡加工出的工件比只经过静平衡加工出的工件，在尺寸、精度上都有很大的提高。现介绍这种结构简单的砂轮... I imported bearings grinder equipped with a wheel balancing device, which just put on the wheel balancing. The results of the comparison between the workpieces with dynamic balance machining and the workpieces with only static balance show that the workpieces that have been machined by the balancing are more precise in size and accuracy than the workpieces machined only by the static balance Great improvement. Now introduce this simple structure of the wheel ...
