Centroid CNC12 Screw Mapping Using Gage Blocks

Post by RGSparber »

Using a set of gage blocks and a finger Dial Test Indicator, this article explains how to accurately measure forward and reverse leadscrew or ballscrew error. Feed this data into the Screw Mapping table.

The intent of Screw Mapping is to take near perfect ballscrews and make them even closer to perfect. What happens when Screw Mapping is applied to the lowly leadscrew on a RF30 Mill/Drill? Leadscrews are far from perfect yet do benefit. The advantages and limitations of trying to turn a sow's ear into a silk purse are presented.

I have made extensive changes to the article. It now includes more measured data plus more theory.
