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 the protective covers for all three axes.
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 cutting. A more accurate, and smoother arc and radius cuts. The pitch of the ball screw is 2mm .07874, whereas the pitch of our leadscrews is either 3820 .050 or 1.27mm
34Mill Ball Screw Z Axis Retrofit Kit. The key upgrade parts for this ball screw retrofit kit include a ball leadscrew, steppermotor coupling, vertical milling column saddle for ball screws, and column saddle Zaxis ball nut mount.
CNCReady ball screw machines are not turnkey machines, and cannot be used until stepper motors have been installed. All machines that are described as CNCready have Stepper Motor Mounts, but do NOT include Stepper Motors, Linux computer amp software, or CNC software.
This oiler system sends lubricant to the lead screws reducing wear. This is very important on a CNC machine as the axis moves much more and much faster than a manual mill ever would. Furthermore, the sherline uses a very simple 1420 UNC threaded rod as the lead screw, which is much higher friction than the ball screw found on most CNC mills.
The XY saddle is much taller on the ball screw mill than on the standard leadscrew mill, and therefore, the metal plates of the accordion covers were increased in size accordingly. Back to Ball Screw FAQ Index. What are some practical benefits of using ball screws vs. leadscrews There is virtually no backlash in the ball screws.

Hugh C has a Sherline CNC mill and CNC lathe and his traveling roadshow posts already point to low rigidity and spindle power when screw cutting on the lathe. If you decide on either the Sherline or Teig, go for the ball screw option and the larger table. Both these features are essential in my book.
Taig Mill Anointed With Ball Screws at Last I see the ball screw upgrade as a huge improvement because climb milling was very difficult to implement and yield good surface finish because of
BALL SCREWS AVAILABLE NOW This video walks you through the steps of removing the leadscrew on a Sherline mill Zaxis column and replacing it with a Ball screw retrofit kit.
I am having problems with 39home39 on my sherline 2000 CNC mill. I made a 234 disc, 0.30034 thick with a 0.20034 center hole on the lathe. I am trying to make 4 holes, in a square pattern centered on the 0 I have a 2000 CNC mill with the ball screw upgrade. I have used the mill for several years. I make more shavings than things. I made a stop
