PTG Heavy Industries builds special-purpose roll grinding machines and offers a complete rebuild and re-engineering service for a wide variety of roll grinders, including models from Waldrich, Churchill and Farrel. Our capabilities include CNC upgrades and converting older roll grinders from manual to full CNC operation. Doing this enhances each machine's original specification to include: in-process gauging and crack and bruise detection, for functionality equal to new roll grinders. We have refurbished a large number of roll grinders to meet today's manufacturing challenges and to grind complex, new roll profiles. We understand the significant demands put on roll grinders, including: tighter tolerance on roll profiles, eccentricity, roundness and taper, new roll compositions, increasing roll hardness and the use of new, bigger grinding wheels.
We have just completed the refurbishment of a Waldrich roll grinder. Visit the used roll grinder page for more information.
