Ball screw kits for Bridgeport milling machines Every Bridgeport mill rebuild has the option to upgrade to a Precision Ball Screw kit, but only 1 in 6 will purchase the upgrade, according to Bridgeport Machine Rebuilders. The initial cost will typically scare off a Purchasing Agent, Maintenance Manager, or Machine Shop Supervisor.
I have ball screws on my Webb 4Vh. (Taiwan). I converted it back to manual from former factory CNC operation. They are terrific. 0 lash on Y and .007 on X. No problem climb milling if table is snugged down. Lots of myths around about negatives of ball screws. My friend has a BP with two full turns of lash with standard screws.
Ball screws make the machine too "slippery" to me for lack of a better term. There is no servo holding the screw on a manual and creeping up on a number is easier with the built in inefficiency of the acme. I did think it a great idea once, threw the ball-screws away and went back. Everyone on the floor hated it so dumpster bound.
The 12″ mill base with ball screws comes with all new saddles developed for the ball screws, and #23 NEMA frame stepper-motor mounts with high-torque couplings. The X/Y-mill saddle has been beefed up to accommodate the larger ball screws, and it has an electroless nickel/Teflon coating.

For the ball screw, I decided to use the nominal 5/8″ size for both fit and cost ($1.09 per inch). The screws and nuts a readily available from MSC, McMaster Carr, and the local bearing outlet. Pricing was about the same from all sources when you use my employer's discounts. There is a large price difference between preloaded ball nuts ...

The key to "ball-screw back-feed" is the screws co-efficient of friction and its helix angle which are functions of the screw pitch diameter and its lead. ie the larger the ball-screw pitch diameter and the smaller its lead the smaller its helix angle will be and the least likely it will be to "back-feed".
Ball screws to replace the table and saddle lead screws; Nut retaining yoke (if required by the machine type) ... The mill can be run manually, as a two-axis or three-axis CNC. Manual quill control is with our unique Electronic Handwheel. Note: For most three-axis CNC applications, we highly recommend TRAK Bed Mills. Top . Sitemap.
The other factor that comes into play in favor of keeping the ball screws is a Lyman MK-7 Power Feed was included with the mill. It could also be used with ACME screws but it fits on the Y-axis ball screw without an extension.
Rolled Ball Screw with BSH Nut.10mm Diameter, 2mm Lead.C7 Accuracy, P1 Preload. The linear accuracy is 50 micrometers / 300mm. Inchs: Rounded up .002″ / 12.0″ = .00016 / 1.0″. Because of the lack of backlash, you can "climb mill" with the ball screws, whereas you have to "conventional mill" with the lead screw. Less chatter when ...
It seems like the main benefits of using ball screws are that: it allows climb milling, you get higher accuracy (no backlash to deal with), and you won't break end mills. But just for the sake of argument, let's say you decidedd to postpone the upgrade to ball screws for a while, but still add stepper motors to your manual mill.

Normally this is not possible with manual machines because the acme screws always have backlash or are to tight to move compfortably. With ball screws and an adjustable drag (and a bit of practice) you will probably be able to effectively climb mill. 05-09 …

The difference in friction, rolling friction of the ball screws and the sliding friction of the acme screw is the problem using ball screws on a manual mill. The acme screw was designed to not rotate under load and therefore will hold a vertical load in place or from pressure from cutting forces.
Roller Screw. Roller screws use rollers instead of steel balls, which reduce the stress concentration due to the greater contact surface area. They offer 1.5-2 times higher loading capacity than a standard ballscrew series and are capable of higher axial loading due to the reinforced circulation system.
The standard lead screws on a Sherline mill are replaced by ball screws to reduce backlash. As a bonus friction goes down dramatically. The video also shows ...
