Ball screw / VFD Upgrade for Enco 9100 (RF30) Looking to do some upgrades to my Enco 9100, which is basically a rebranded Rong Fu RF30. Eventually I'll be doing a CNC conversion to it, but beforehand I'd like to upgrade to ballscrews, and a VFD since the pulley system that's currently on it kind of sucks. I was looking at this for the ballscrews;
Proper ball screws have two nuts with a spring between them to take up almost all slop. My 1977 model Boston Digital CNC mill has about .00056" backlash due to large screws with spring loaded nuts. A friend spent a ridiculous effort and money to convert a good BP to ball screws and add CNC. He has .002" backlash.

The 4hole pattern shown in the pic is on the side of the tractor chassis and is one place that the mounting brackets will attach to. The purpose of making the transfer screws, which are M14 x thread, was to measure accurately the hole locations which is not a square pattern. You may notice the point on the end of the screws which normally ...
A Ballscrew (sometimes spelled Ball Screw) is a type of linear actuator that translates rotary motion into linear motion. It uses ball bearing in a helical groove to transfer the motion with very little friction. Because of this low friction fit, ballscrews have less backlash or slop than Acme leadscrews and allow you greater repeatability.
Adding ballscrews and other upgrades to our Axminster SIEG Super X1 Micro Mill. Our original milling machine has undergone several modifications since we purchased it. First was a new longer bed and then a DIY CNC conversion with the control box being relocated, and in December 2009 we purchased a belt drive kit to make it quieter to use.

Conversion of a Grizzly G1005 Mill/Drill to Preloaded Ball Screw CNC The Quest For Zero Backlash Follow the links to pictures and captions as you read. I decide to convert the mill/drill to have zero backlash in at least the X and Y axes. Again, at the lowest possible cost. I accomplished this with ball.

I went to an auction recently and picked up a set of screws that turned out to be ball screws for a 9x42 Bridgeport. formatting link I am a little surprised about it, as, I thought, ball screws could only be used in CNC mills whose screws were held by stepper motors.

I converted an RF30 many years ago as cheaply as possible sort of. Even after making the mounts and brackets myself I had 1k in it. Nema 23's are going to need som good gear reduction to work IMO, especially with original acme screws. I used ball screws driven 1:1 with nema 40 500 ozin motors XY, geco drives, and homemade 72vdc power supply.

#1 Just toying with the idea of converting to ball screws on my mill but I know nothing about this kind of conversion The currently has 28mm dia feed screws on the X and Y axis, would I need to be getting ball screws with a similar dia screw? Mill is an old Warco WM20 or similar, table size is approx 900mm x 225mm
Rong Fu RF30 Conversion. A few months ago I took some tentative steps to begin the process of converting my RF30 to CNC. I bought some SF1605 ball screws with ball nuts. These had no machined ends, just ball screw end to end. I also bought some NEMA 23 Steppers rated at 3 amps, 370 Oz In. I finally began work on in earnest on this project ...
