Ball screw in CNC milling machines and heavy industrial machinery. There are two types of spindles: lead screws and ball screws. The lead screw has a much simpler design, comprising a screw and a nut, so that the rotary motion of the screw is converted into the linear motion of the nut. Due to the continuous sliding contact …

Because of the lack of backlash, you can "climb mill" with the ball screws, whereas you …
Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start ball screws and nuts, they have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts. To ensure compatibility, select …
I am thinking of replacing the Acme screws on my 20 + year old Enco …

Ball screws are very similar to recirculating ball bearing systems, using the same rolling properties of ball bearings to convert the motion. Ball bearings roll inside of special grooves cut into the ball screw and nut, allowing for lower friction (and thus a smaller motor), higher precision, and the ability to run under high cycle conditions. ...
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".
My 1987 Taiwan Webb 4VH 10 X 50 mill (3,500#) came to me with ball screws and servo motors but no computer. It had been a factory CNC modification that had quit working, The machine was very sound and I refurbished it with manual controls but left the ball screws in place. The X axis has about 7 degree marks of backlash total (3.5 …
This covers most of the parts needed to build the mill, except the stepper motors, drivers, power supply and the controller. I intentionally decided to punt on this while doing some more research. My total out of pocket cost so far is as follows: Missing cast iron parts - $226; Ball screws and axial bearings - $130; Spindle bearings - $96
The ball screw drive is an assembly that converts rotary motion to linear motion (or vice versa). It consists of a ball screw and a ball nut packaged as an assembly with recirculating balls. The interface between the ball screw and the nut is made by balls which roll in matching ball forms.
The mechanical part consists of replacing the lead screws in the mini-mill with ball screws and double nuts. The reason why you need a new mechanical system is that the lead screws in benchtop mills have backlash and are not really built for CNC operation. Ball screws have very little backlash and are an excellent choice for a CNC …
