PMI Precision Motion Industries
The production of the PMI rolled ballscrews has adopted a manufacturing process and equipment unlike other manufacturers. Combining advanced skills and the Bad Düben digital electric screw thread rolling machine, we adhere to a strict quality control policy at every stage of production, from the selection of ballscrew material and rolled processing to induction hardening heat treatment and post production. We are committed to providing clients withproducts of the best quality. The combination of rolled ballscrews and ground nuts has replaced the traditional ACME screws and trapezoidal screws. This makes for a smoother operation while lowering friction and backlash. Moreover, the new technology has the advantage of faster production speed and lower prices. Besides differences in the definition of lead deviation and geometric tolerance, rolled and ground ballscrews can both eliminate axial play by preloading. Please contact us for related technical information.* C7, C8, and C10 Screws have been Standardized The lead accuracy of our rolled ballscrews is in accordance with JIS B1192 -1997, and our C7, C8, and C10 products have been standardized.* Lead Accuracy Up to Grade C5 Lead accuracy grade can be as good as JIS Grade C5 and C6. Please contact us if you have need for such high accuracy grades.* High Precision Rolled Nuts The manufacturing process of rolled nuts is identical to that of ground nuts. Surface hardening treatment and internal thread grinding ensure durability and smoothness.* Nuts are Interchangeable Without preload and within the maximum permissible axial play, different types of nuts can be used on the same screw.
