A mirror surface finish of our hard XC1000 carbide coating can reduce the requirements to remove and clean a feedscrew.

Most large diameter feedscrews have chrome plating surface treatment to the screw core.  On a new screw this is a smooth surface that resists material build up.  Eventually, with resins that are prone to sticking on the screw surface, a feedscrew must be removed for cleaning.  Even careful handling of chrome plating will leave small scratches on the surface.  These areas then foul more rapidly and the screw must again be removed and cleaned.  XC1000 is 5-10 points harder on the Rockwell scale them chrome plate and will not scratch during cleaning.  Our super surface finish .1 Ra µm reduces COF and ensures a long time between cleaning episodes.
