Properly ground rolls are crucial to 1) coating quality and 2) your productivity and cost objectives. While the coating processes are numerous, it all comes down to a few basic goals in each of these areas:
The accuracy of your roll grinds determines your ability to achieve coating weight and thickness objectives. Additionally, precise grinds lead to increased line speeds, reduced downtime, higher yields and lower material usage.
That’s why Precision Roll Grinders considers lower process costs and precision grinding services to be two sides of the same coin. With industry-leading grinding from PRG, your long-term manufacturing costs decline because the quality and life span of your rolls are considerably enhanced.
In fact, the accuracy of PRG’s roll grinding is sure to become a key factor in your Six Sigma improvement efforts.
PRG is recognized as having the best roll grinding technology, expertise and resources available, PRG ensures world-class levels of precision in surface finish, roundness, TIR and profile.
After grinding, many roll reports show “radius based measurements.” This has a detrimental effect to the accuracy of your specifications because the radius based measurements make the roll data look much better than it really is. PRG’s measurements are made based on the diameter, not the radius, of the roll.
