Here’s an X-axis slide from a hybrid machine with a linear guide on the Z-axis and a metal-on-metal dovetail boxway on the X-axis. Over time, debris wore down the front of the slide, damaging the top surface and the master. This damage caused repeated ball screw failures.
To fix the problem, we took the slide apart, ground the top surface and the master, and then hand-fit the slide back in place. Rather than replacing the gib, we realigned it and used Moglice as a filler to build it up. After removing material from the flat, we adjusted the gib side to keep everything flat, parallel, and aligned.
We also elongated the ball screw mounting holes and indicated everything on the master to prevent binding. In some cases, Turcite can be used to bring the slide back to centerline; however, on this job, we opted for metal-on-metal because the amount of material removed was relatively small.
The key takeaway is that frequent ball screw failures usually aren’t caused by the ball screw itself or the installer—they’re caused by misalignment from machine wear. Proper regrinding, fitting, and alignment solve the root problem.
