PRG roll grinding

Superior product performance can often be achieved through precision roll grinding. PRG is able to grind to tolerances plus & minus 20 millionths of an inch total indicated run-out, and achieve surface finishes less than 0.5 micro inch Ra.

A more precise grind means a more precise nip: uniform pressures, uniform caliper, uniform wear profiles, no "break-in" requirements, improved sheet consistency and longer time between grinds - all of which, obviously, means higher profits for our customers.

PRAXAIR^TM coatings

PRG is an authorized distributor for Praxair carbide and ceramic coatings. Replacing chrome plating or resurfacing worn chilled cast iron with tungsten carbide, chrome carbide or ceramic can increase run times dramatically and improve uniformity as well as release. And with several offerings per application, coatings are tailored to your operations and budget requirements.
