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.

滾道輕微局部研傷

Slight local abrasion of raceway

可用金剛銼或油石將研傷起線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.

損傷的滾珠絲杠滾道能否呢？

Can the damaged ball screw raceway?

滾道整體輕微研傷

Slight grinding damage to the whole raceway

將滾珠絲杠置于螺紋磨床兩頂間，找正后精磨。應(yīng)嚴(yán)格控制修磨量，不能太大，這樣修出來(lái)的絲杠副可不更換絲母，通過(guò)調(diào)隙或更換稍大點(diǎn)的滾珠來(lái)恢復(fù)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.

滾道嚴(yán)重研傷

Serious grinding injury of raceway

將滾珠絲杠同上法在螺紋磨床上磨削。修磨量根據(jù)研傷程度確定，并按相近直徑系列的鋼球尺寸進(jìn)行精磨。中徑尺寸及公差和螺距不變，只是改變了滾道的“R”值，然后按“R”值更換上新的鋼球，配做新的螺母。這樣修出來(lái)的絲杠應(yīng)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.
