滾珠絲杠有時候在使用的過程中會出現問題，維修不恰當的就會造成數控機床無法工作，這樣出現了問題，就要自己檢查，發現故障原因。下面導軌絲杠廠家就來說說滾珠絲杠維修的過程：

The ball screw sometimes has problems in the process of use. Improper maintenance will cause the CNC machine tool to fail to work. If there is a problem, you should check it yourself to find the cause of the problem. The guide screw manufacturer will talk about the maintenance process of ball screw:

1.拆開檢查。

1. Disassemble and check.

將回珠器取出螺母，從其安裝孔內相繼將鋼珠也取出，松開連接部件，拆下壞螺母（另一螺母未損壞，不拆）。發現絲杠、螺母的部分滾道、回珠器滾道被擠壓變形，個別鋼珠破裂，所以鋼珠不能在滾道內正常滾動。

Take out the nut of the ball return device, take out the steel ball from its mounting hole one after another, loosen the connecting parts, and remove the bad nut (the other nut is not damaged, do not remove it). It was found that part of the raceway of the lead screw and nut and the raceway of the ball return device were extruded and deformed, and some steel balls were broken, so the steel balls could not roll normally in the raceway.

2.部件修整。

2. Component repair.

各部件清洗后詳細檢查受傷情況。用銼刀，油石清理變形部位，因擠壓而高出原位的凸起部分：絲杠上嚴重變形的前兩圈螺紋用車床車削成光滑外圓，使其直徑小于或等于絲杠小徑，銳邊倒鈍。

Check the injury condition of each component in detail after cleaning. Clean the deformed part with a file and oilstone, and the protruding part that is higher than the original position due to extrusion: the first two threads on the lead screw that are seriously deformed are turned into smooth outer circles with a lathe, so that their diameter is less than or equal to the minor diameter of the lead screw, and the sharp edges are blunt.

3.試裝螺母。

3. Try to install nuts.

回珠器、螺母再經清洗，檢查無誤后，將前者裝入后者，注意傾斜角度適當—回珠槽進出口與滾道接口在底部和兩側相切，方便滾珠工作時自由出入。

After the ball return device and nut are cleaned and checked to be correct, install the former into the latter. Pay attention to the proper tilt angle - the inlet and outlet of the ball return groove and the raceway interface are tangent at the bottom and both sides to facilitate the free access of the ball when working.

4.旋和。

4. Rotate and.

螺母滾道與回珠器回珠槽道涂抹油脂，粘上鋼珠，旋入。旋和中認頭相當困難，稍微旋動，滾珠就亂了，或者個槽順利擰入，第二槽就擰不進去。

Apply grease to the nut raceway and the ball return groove of the ball return device, stick the steel ball and screw it in. It is quite difficult to recognize the head in the middle of rotation. If you rotate slightly, the ball will be disordered, or the first slot will be screwed in smoothly, but the second slot will not be screwed in.

5.研磨。

5. Grinding.

絲杠未壞掉處，三周均勻沾15-20個鋼珠，作為研具。將取出鋼珠的螺母清洗后，試驗擰入，感覺稍緊。

15-20 steel balls shall be evenly smeared on the three sides of the lead screw where it is not damaged as a grinding tool. After cleaning the nut that takes out the steel ball, screw it in and feel slightly tight.

6.總裝后檢測。

6. Inspection after final assembly.

將各部件重新裝入數控車床，潤滑部位涂滿油脂，開始試車。徒手旋轉絲杠，也沒有阻力，Z軸正常運轉，床案移動正常。

Reinstall all parts into the CNC lathe, coat the lubricating parts with grease, and start the test run. Rotate the lead screw without resistance. The Z axis operates normally and the bed table moves normally.

以上就是滾珠絲杠維修的過程，如果出現了問題，要小心的維修，要是自己沒有把握的還是請專門的技術人員來維修，這樣也好一點。您可以關注我們網站http://www.pet998.com，了解更多事項！

The above is the maintenance process of the ball screw. If there is a problem, you should be careful to repair it. If you are not sure, you should ask a special technician to repair it. This is also better. You can follow our website http://www.pet998.com , learn more!
