HOW TO DO A BALL SCREW MACHINING?

How to do a ball screw machining? 

First, Reducing hardness.
Surface hardness of ball screw shaft is around HRC58. It’s too hard to machine directly, so you need to reduce hardness of the sessions you need to machine. You can use High frequency machine with electric current 800A to do so.

Second, Straightening ball screw shaft.
The ball screw shaft is easy to bend during transportation and storage. It isn’t straight enough to machine directly. So you need to adjust the straightness for better machining.
