磨床是金属切削中必不可少的设备,为了使砂轮在磨削过程中正常运转,它必须经过平衡。因为未经平衡的砂轮,它的重心与旋转中心不相重合,存在一定的偏离。当高速旋转时,即使偏离的距离e很小,根据F=meω~2(式中m为砂轮质量、ω为砂轮转速,可知将会产生较大的离心力,导致砂轮发生振动,影响加工精度。砂轮的不平衡是造成磨床主轴振动的主要原因之一,振动的机床将会影响零件的加工 Grinding machine is essential for metal cutting equipment, in order to make the grinding wheel in the normal operation of grinding process, it must be balanced. Because of unbalanced wheel, its center of gravity does not coincide with the center of rotation, there is a certain deviation. When high-speed rotation, even if the distance e is small, according to F = meω ~ 2 (where m is the quality of the grinding wheel, ω is the wheel speed, we can see a greater centrifugal force, resulting in grinding wheel vibration, affecting the machining accuracy. Wheel imbalance is one of the main causes of grinding spindle vibration, vibration of the machine will affect the processing of parts
