Precision Grinding: 5-Step Roadmap To Production Efficiency

Posted by Robert Rourke on Jul 21, 2014 10:30:00 AM

A smooth production line is at the crux of your company's efficiency, productivity and quality output – and nothing slows down a production line faster than inconsistent roll grinding, maintenance and early replacement. So it only takes a shred of logic to see that production efficiency is a path paved by precision grinding.

 First, let’s recall the importance of your rolls. Then, we’ll shine some light on that path to production consistency.  

Your Rolls Set The Scene

Production efficiency, profitability and quality are all determined by the grinding precision your rolls received.

  • Roll-swap downtime is a big pill to swallow, but that’s just the tip of the iceberg.
  • When your line is rife with grinding negligence and rolls that are out of spec, those band-aid costs build up and bite big into profit.
  • Last but certainly not least is that product at the end of the line. In the ruthless realm of rolling mills and calenders, even miniscule imperfections take a diabolical toll on quality – putting customer loyalty in dangerous territory.

Precision Grinding Stepping Stones

Pave that path to production efficiency with production-priming precision grinding. Here’s the five-step roadmap:

  1. Concentricity

Concentricity is the most important factor in preventing roll degradation. Make sure your rolls are truly round and concentric to the bearing seat prior to installation.

  1. Profile And Spec Check

Double check that your rolls are ground to the necessary specifications (or better!) and that your grind profiles are exactly what you requested. Out-of-spec rolls take a serious toll on sheet quality and consistency.

  1. Barring And Feed Lines

Inspect all the rolls in a multi-nip position to ensure they’re free of barring, feed lines and chatter. Even the slightest surface inconsistencies snowball exponentially once operation is at full speed.

  1. Coatings

Use coatings on all applicable rolls. Surface coatings, like Roll Armor®, protect rolls from wear and extend production life, cutting down on replacements and downtime.

  1. Bearings And Bearing Seats

Partner with a roll grinding provider that regularly and meticulously inspects each roll’s bearings, verifying and correcting (if necessary) the size, geometry and contact of bearing seats.
