Ball screw failure is most often caused by the gradual degradation of the ball screw surface through metal to metal contact of the re-circulating balls to the hardened metal surface of the ball screw shaft. Another possible cause could be a machine crash where the abrupt excessive load and rapid deceleration can cause buckling of the ball screw shaft and damage to the ball nut itself, including splitting some of the re-circulating balls within the ball nut. Whatever the cause, our highly skilled craftsmen have 40 years worth of experience in ballscrew repair process. Each ballscrew is ground and super polished to a mirrior finishes for longer service life. They are individually preloaded to the highest possible positioning accuracy. They look and perform as they did when new. We will only repair your ballscrew unit if we know that you will gain a cost and/or time saving by doing so when compared to buying new unit. Generally a repair is the best option but if not we will tell you immediately. Correct ball size and quality is critical to achieve superior positioning accuracy, repeatability, and long ball screw life. If the ball size is incorrect a ball screw will never achieve its designed positioning potential. If the material hardness, spherical accuracy, or surface finish is incorrect the wear characteristics of the ball screw will be seriously compromised. In our Ball Screw Repair process we only use balls of equal or better quality than were installed by the original ball screw manufacturer. Some of our competitors are satisfied to install the minimum quality Grade 25 chrome steel balls that are cheaper and more easily obtained in multiple sizes than high quality balls. We, however, predominantly use Grade 10 for balls 0.1 inch to 0.375 inch in diameter, Grade 5 for balls less than 0.1 inch, and only use Grade 25 for balls over 0.375 inch diameter because this grade is only accurate enough for the larger size balls. We stock almost every size of ball in at least 0.000050 inch (50 millionths) increments, which be believe is absolutely necessary to be able to recondition all types and sizes of ballscrew correctly with a quick turnaround. To stock hundreds of ball sizes of predominantly Grade 10 quality is beyond all but the most reputable and committed companies.
