一、概述 机床主轴质量不均衡而引起不平衡量的大小和位置总是任意的,将导致机床主轴产生不平衡振动,其振动具有与轴的旋转相同周期的特征,易于识别。消除这种振动的有效方法是在低速平衡机上对主轴进行校正,也即在主轴不平衡的方位选择两个校正平衡面,利用调整质量的办法使其? First, an overview of the uneven quality of the spindle caused by the imbalance in the size and position is always arbitrary, will lead to machine tool spindle imbalance vibration, the vibration has the same cycle with the axis of rotation characteristics, easy to identify. An effective way to eliminate this kind of vibration is to calibrate the spindle on the low-speed balancing machine, that is, to select two calibration balance surfaces in the unbalanced orientation of the main spindle. By adjusting the quality,
