Feb 28 2008018332A lot of joy can be had be rough grinding them first You have the minor diameter to use as a guide grind down to that using a hand or pedestal grinder Or mask your machine up and try it with a tool post grinder if you have one If youre putting a centre in it expect that to move once you have broken the case hardening.
Apr 06 2016018332The rolling and grinding processes produce different surface finishes A rough surface finish is problematic in ball screw assemblies because it can result in higher friction and more wear on the loadcarrying balls The grinding process produces a very smooth surface finish and in theory the rolling process does as well.
Thread grinding is a form of threading during which a CNC machine with an abrasive grinding wheel is used to cut the threads of the screw Screws created through thread grinding are able to meet custom backlash requirements and tight tolerances.
Ballscrews consist of a screw spindle and a nut integrated with rolling elements that cycle through a return mechanism Ballscrews convert rotary motion into linear motion and are most commonly used in industrial machinery and precision machines.
