在机械加工中 ,常常需要检测零件的径向跳动 ,最常用的检测方法是在偏摆仪上顶住零件或芯轴 ,通过转动零件或芯轴来检测零件的径向跳动 ,这种方法在大批量生产中存在问题较多 ,尤其是对精密零件大批量加工中径向跳动的检测 ,一般不宜使用。图 1　测量示意图如锭盘的检测 ,采用 In machining, often need to detect radial runout parts, the most commonly used detection method is to swing the instrument to withstand parts or mandrel, rotating parts or mandrel to detect the radial runout, this method in There are more problems in mass production, especially for the detection of radial runout in high-volume machining of precision parts, which is generally not suitable for use.
