对于机床生产厂家来说，如何平衡垂直运动部件的重量一直是个需认真考虑的问题。通常平衡的方法主要有三种：第一是当垂直运动部件的重量较轻时，可采用直接加粗传动丝杠，加大电机扭矩的方法。但这样将使得传动丝杠始终承担着运动部件的重量，导致单面磨损加重，影响机床精度?
For machine tool manufacturers, how to balance the weight of vertical moving parts has always been a serious consideration. Usually there are three main ways to balance: The first is the weight of the vertical moving parts lighter, you can use direct bold drive screw, increase the motor torque method. But this will make the transmission screw always bear the weight of moving parts, resulting in increased single-sided wear, affecting machine accuracy?
