From rubber bands to tires, PRG handles even the largest manufacturing equipment. In addition, all work is performed at our facilities, guaranteeing the grind is done right the first time.


In-Place (Block Grinding) vs. Precision Roll Grinding

For all aspects of the rubber industry, off machine roll grinding is better than in-place roll grinding. In-place (block) grinding is done in bearings on the machine, which does not produce rolls that meet the original specifications. If something is off on one side or anywhere on the roll, it can’t possibly attain proper shape, roundness and TIR. With PRG, all roll grinding is done at our facilities on the most modern and accurate grinders in the world. It’s a proven process guided by computer data. Bearings and housings are removed to guarantee a perfectly round roll in a temperature-controlled facility. In addition, all rolls are measured using a 24-point SpecCheck™. PRG never blindly assumes bearings are working properly and that the journals are without issues such as chatter or lack of roundness.

The result? Benefits that meet or exceed OEM specifications:

  • Significant improvement in mill productivity and profit for the manufacturer
  • Increased run time of rolls
  • Removal of roll corrugations and defects
  • Control surface finish to minimize start up time
  • Reduced bearing failures
  • Energy savings
  • Complete hardness mapping of roll face available
  • Reestablish end relief for proper operation
  • Uniform surface finish using grinding wheel, not blasted
  • Rolls are installed in “ready to run” condition
  • Achieve tolerances of ±20 millionths of an inch
