PRG's process delivers concentricity and roundness from less waste in rolled sheet productions
To produce high-quality, finished stock from less raw metal, progressive steel and aluminum mills are discovering
the roll refinishing benefits of PRG — the industry leader in roll technology. PRG can provide a spectrum of
roll care services typically unavailable from in-house grinding operations.
PRG grinds the entire journal as well as the barrel
Unlike many in-house grinding operations, PRG has the technology to grind the entire journal areas of each roll,
as well as the barrel surface. Our craftsmen and specialized grinders can achieve .0001 TIR on roll bearing seats
and setup spots. By optimizing concentricity and roundness, specialty sheet stock manufacturers are realizing
these competitive advantages:
More finished stock from less raw metal
Longer life and productivity between regrind intervals
Less vibration to affect other machine areas
Lower maintenance costs and less downtime
