At PTG Heavy Industries we have rebuilt and re-engineered a large number of Roll grinders of various manufacturers including Churchill, Farrel, etc. This work includes conversion from manual to CNC which enhanced the machines original specification to include in-process gauging and crack and bruise detection providing functionally equal to new roll grinders.

A typical recent project was the re-engineering of a Farrel machine originally supplied to British Steel in the 1950’s. We re-built the machine and included 3 axis CNC control with easy to use front end and convenient data entry allowing any roll camber data to be input easily without complex programming.
