Rolled screws were typically used in non-precise applications, such as in pick-and-place devices, and as actuators. Ground ball screws were used as the drive mechanism in precision machine tools (milling machines, lathes, profile grinders, turning centers, EDM machines, and so on). Additionally, ground ball screws have been the product of ...

For ground ball screws, both thread grinding and journal grinding are done using the same reference centers, making it easier to minimize radial run-out and to keep the screw threads and end journals concentric. When screws are manufactured by rolling, the end journals are machined and ground after the threads are rolled, so maintaining ...

A rough surface finish is problematic in ball screw assemblies because it can result in higher friction and more wear on the load-carrying balls. The grinding process produces a very smooth surface finish, and in theory, the rolling process does as well.

The Ball Screw requires a minimal starting torque due to its rolling motion, and does not cause a slip, which is inevitable with a sliding motion. Therefore, it is capable of an accurate micro feeding. Fig.4 shows a travel distance of the Ball Screw in one-pulse, 0.1-μm feeding. (LM Guide is used for the guide surface.)

Ground ball screws are created through an abrasion process, during which a very hard abrasive cutter moves along the length of the horizontally positioned blank, carving out a few threads of the screw at a time. In contrast to ground ball screws, rolled ball screws are manufactured using rotating tool dies.
