Hot Grinding

Hot grinding is often the solution to production challenges caused by excess distortion as a result of high-temperature operations. Rolls are carefully examined and then heated to operating temperature -- up to 600 degrees Fahrenheit. Then, we grind them to PRG accuracy for a roll that starts up and operates just the way you need it to, increasing quality and production.

Our proprietary hot grinding technique is the only one of its kind in the North American market, and we continuously add the latest technology to our grinders.

"I highly recommend Precision Roll Grinders. They gave us the exact dimensions and specifications that we requested -- delivered on time and completely wrapped. The people at PRG were knowledgeable, responsive and easy to work with. They even encouraged us to contact them on weekends. If I had another roll grinding emergency, I would insist on using PRG, even if I had to send my rolls much farther!"
