Ball Screw FAQs – Sherline Products

The pitch of the ball screw is 2mm (.07874″), whereas the pitch of our leadscrews is either 3/8-20 (.050″ or 1.27mm) or 10x1mm (1mm or.03937″). Therefore, you have a more significant travel distance per revolution. The ball nut and ball screw combination will give your machine a much smoother motion.

3D Pocket Clearing - manual Stepover for Ball endmills

If you are using an 8mm ball mill, then 6mm stepover is still very aggressive and will leave a very irregular surface for the finish pass. The goal is to get as uniform a surface as possible for the finish pass so the cutter bends by a uniform amount. Any change is the amount of force on the cutter will show up on the surface of the finish cut.
