滚珠丝杠有时候在使用的过程中会出现问题，维修不恰当的就会造成数控机床无法工作，这样出现了问题，就要自己检查，发现故障原因。下面导轨丝杠厂家就来说说滚珠丝杠维修的过程：

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.拆开检查。

1. Disassemble and check.

将回珠器取出螺母，从其安装孔内相继将钢珠也取出，松开连接部件，拆下坏螺母（另一螺母未损坏，不拆）。发现丝杠、螺母的部分滚道、回珠器滚道被挤压变形，个别钢珠破裂，所以钢珠不能在滚道内正常滚动。

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.

各部件清洗后详细检查受伤情况。用锉刀，油石清理变形部位，因挤压而高出原位的凸起部分：丝杠上严重变形的前两圈螺纹用车床车削成光滑外圆，使其直径小于或等于丝杠小径，锐边倒钝。

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.试装螺母。

3. Try to install nuts.

回珠器、螺母再经清洗，检查无误后，将前者装入后者，注意倾斜角度适当—回珠槽进出口与滚道接口在底部和两侧相切，方便滚珠工作时自由出入。

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.

螺母滚道与回珠器回珠槽道涂抹油脂，粘上钢珠，旋入。旋和中认头相当困难，稍微旋动，滚珠就乱了，或者个槽顺利拧入，第二槽就拧不进去。

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.

丝杠未坏掉处，三周均匀沾15-20个钢珠，作为研具。将取出钢珠的螺母清洗后，试验拧入，感觉稍紧。

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.总装后检测。

6. Inspection after final assembly.

将各部件重新装入数控车床，润滑部位涂满油脂，开始试车。徒手旋转丝杠，也没有阻力，Z轴正常运转，床案移动正常。

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.

以上就是滚珠丝杠维修的过程，如果出现了问题，要小心的维修，要是自己没有把握的还是请专门的技术人员来维修，这样也好一点。您可以关注我们网站http://www.jngongrun.com，了解更多事项！

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.jngongrun.com , learn more!
