Let's face it, sometimes
unexpected failures happen.
Ballscrews fail in machine tools due to one or more of these conditions…
- Normal wear, contamination, corrosion, brinelling, galling
- Poor maintenance (lack or excess of lubrication)
- Accidents resulting from electronic malfunctions
- Poor design-under capacity
- Overloaded or too high of a preload
- Bent O.D. of Shaft or Broken bearing journals
- Vibration or Misalignment (due to improper installation)
- Environmental
- Operator error
- Spalling / Flaking
Solution -
Ball & leadscrews are machined from top quality material, hardened and ground to super-precision tolerances. They usually do not need replacing when worn. As a result, it is economically feasible to service all types of ball screws by,
-
Regrinding O.D. of the screw
-
Regrinding I.D. or replacing ball/ballnuts
-
Resetting preload back to OEM specifications by replacing balls
-
Full torque testing
