To guarantee a product, a company needs to be confident that it is suitable for the task it was intended and will stand up to the stresses of every day use. To insure satisfaction and long life, Express Ball Screw Repair Service uses only the best quality parts and super fine finishes when it rebuilds one of its ballscrews. Each ball screw is individually processed, preloaded and tested and in some cases tailored to a customer's special requirements. Express Ball Screw Repair Service does not use an assembly line system, each unit is unique unto itself.
Why scrap a perfectly serviceable ball screw when it can be reconditioned?
After rebuilding, one of our ballscrews can reasonably be expected to double its service life, with an appearance and performance equal to or superior to a manufacturer's replacement ball screw. And, because a replacement may not be in stock or is an expensive special order item, repairing your existing ball screw could save you downtime and will definitely save you money.
Why spend more than you need to?
Why suffer more downtime than you need too?
A word about Ball Size and Quality
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.
Quality precision ballscrews feature consistent ball to raceway load over every revolution of each load ball for the entire length of travel. To achieve this goal it is not only necessary to accurately machine ballscrew parts, but to provide a surface finish suitable for the ball to run along without abrasion. Finish lapping and polishing the raceway of the screw and recirculating ball nut is useless if the balls running along them do not at least match the accuracy and surface finish. Because a load ball is in constant contact with the raceway but traveling along the track, the wear to the balls exceed wear to the raceway. For a ball screw to perform flawlessly over a period of time the quality and accuracy of the balls are paramount to a high precision ball screw.
Unlike many ball screw reconditioning companies, Express Ball Screw Repair Co. uses balls of equal or better quality than were installed by the original ball screw manufacturer. Many 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.
Express Ballscrew repair predominantly uses 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. To recondition all types and sizes of ball screw correctly it is necessary to stock almost every size of ball in at least 0.000050 inch (50 millionths) increments. To stock hundreds of ball sizes of predominantly Grade 10 quality is beyond all but the most reputable and committed companies.
The balls that go into your ball screw help determine the quality of the finished product so be satisfied that the balls being installed are the correct grade.
