Bridgeport Ball Screw Repair
There are thousands of Bridgeport knee mills in use today, so we get a lot of ball screw assemblies from these sent to us for rebuild. Mostly they are from the X and Y axes (located under the table), but we also rebuild some Z axis screws (from the quill). The rebuilds for these milling machines are also quite affordable, therefore it is economically a great option versus buying new. See pricing below:
One huge advantage you have when you rebuild these screws rather than purchasing new is you eliminate the possibility of the screw not fitting in the machine, since we recondition the actual ball screws you send in. Another advantage to rebuilding instead of replacing with new is that the original ball screws in these machines are high quality, usually made by Hiwin, Tsubaki, or 20th Century Machine, whereas most replacement screws available today are made in China or Taiwan.
For rebuild pricing on any other types of Bridgeport machines such as CNC lathes and machining centers, please contact us.
