27/02/2005· Older NC and CNC Bridgeports and especially those that never had hand wheels will come with chrome ways, ball screws and either stepper or servo motors. Lack of handwheels coupled with troublesome controls resulted in a good number of these machines being found with ways and ball screws in very nice shape. I sold the mill drill and bought a

Mill/Drill, Version 1.2 By R. G. Sparber Copyleft protects this document. 1 Conclusion I was able to reduce X axis backlash to 0.002 inches without binding of the leadscrew. This was accomplished by preloading the bearings, modifying the take up nut, preventing any slip in the gib, and aligning the leadscrew.

It isn't. I wanted a ball turner and I wanted it fast! This is an easy project to build, though you do need to hold close tolerances on the bearing bores. I designed and built it over a three day weekend, and only a few hours a day were available to work on it. In fact, I don't even own a proper mill, just a Grizzly mill/drill.

17/12/2010· Removing backlash in cross-slide handle. I'm slowly trying to "square" my Sieg C4 lathe. So far I've adjsuted the gib on the compound and on the cross-slide, and it behaves better. After adjusting the gib on the cross-slide, I've noticed some backlash in the handle, maybe .004", meaning that if I turn clockwise, I have to move counter clockwise

17/03/2020· I'm looking for a source for a low-backlash ball screw for the quill of my Fehlmann mill-drill (see my previous thread on this machine). The machine was previously set up with a very nicely constructed worm and wheel drive to the quill rack and pinion, but backlash in the worm and wheel (not the rack and pinion) has led me to consider using a ball screw instead.

16/05/2019· The "nut" uses recirculating ball bearings for extremely low friction and tight tolerances–little or no slop compared to an acme thread. Ballscrews are typically intended for CNC work, and so are made to minimize backlash. Because they turn with a lot less friction than an ACME screw, they can be built to much tighter tolerances.
