这种千分塔的主要缺点,是接触较小,磨损较快,但可以作为临时解决问题的一种办法。为了减少几何形状误差的影响,可在端面上刻刻出标线,就标线位置测定实际尺寸。
The main disadvantage of this kilometer tower is less contact and faster wear and tear, but can be used as a temporary solution to the problem. In order to reduce the impact of geometric errors, the marking can be engraved on the end face to determine the actual size of the marking line.
