Although the ball screw has the characteristics of quality assurance and high stiffness, it will also cause certain damage to the ball screw if it is overloaded for a long time or improperly operated. In particular, it has a certain impact on the raceway. Can the damaged raceway still be? The answer is yes, and different methods can be adopted according to the damage degree of the raceway. Let's introduce it in detail below.

滚道轻微局部研伤

Slight local abrasion of raceway

可用金刚锉或油石将研伤起线的部位局部修整平滑。

Diamond file or oilstone can be used to trim and smooth the part of the grinding line.

损伤的滚珠丝杠滚道能否呢？

Can the damaged ball screw raceway?

滚道整体轻微研伤

Slight grinding damage to the whole raceway

将滚珠丝杠置于螺纹磨床两顶间，找正后精磨。应严格控制修磨量，不能太大，这样修出来的丝杠副可不更换丝母，通过调隙或更换稍大点的滚珠来恢复其功能及精度。

Place the ball screw between the two tops of the thread grinder, align and finish grinding. The grinding amount shall be strictly controlled and shall not be too large. In this way, the repaired lead screw pair can not replace the screw nut, and its function and accuracy can be restored by adjusting the gap or replacing the slightly larger ball.

滚道严重研伤

Serious grinding injury of raceway

将滚珠丝杠同上法在螺纹磨床上磨削。修磨量根据研伤程度确定，并按相近直径系列的钢球尺寸进行精磨。中径尺寸及公差和螺距不变，只是改变了滚道的“R”值，然后按“R”值更换上新的钢球，配做新的螺母。这样修出来的丝杠应完好如新。

Grind the ball screw on the thread grinder in the same way as above. The grinding amount shall be determined according to the grinding degree, and the fine grinding shall be carried out according to the steel ball size of similar diameter series. The pitch diameter dimension, tolerance and pitch remain unchanged, but the "R" value of the raceway is changed, and then a new steel ball is replaced according to the "R" value, and a new nut is made. The lead screw repaired in this way shall be as good as new.
