CBR provides ball screw repair for lasers, water jets, routers, and more.


What causes worn, loose, and noisy ball screw assemblies?

Most CNC metal-working machines tend to loosen up with age and production hours. It is very common to see laser machines with only 4,000 to 6,000 hours on them showing “hole out-of-round” problems, tool chatter, loss of stiffness, interpolation errors and poor finish pass accuracy. These issues are not a machinery quality problem; it is usually caused a ball screw assembly worn from abrasive cutting effluents suspended in the air and blown around by the assist gas. This dust is very fine and tends to coat everything on or near the machine, impacting the integrity of the ball screw assembly.

Over time, this leads to the need for ball screw repair, restoration, or worst-case scenario – replacement. Regular preventive maintenance with CBR can extend the life of your ball screw.

Field service CNC ball screw repair ensures the least downtime and the least lost production.

Even with travel expenses, our prices are lower than most repair depot estimates/invoicing. See our Cost Examples page for a sample comparison and contact us for a custom service quote.
