Roll Grinding

Roll Grinding

Experience and Exactness

If you want the highest quality surface for your rolls, come to Rockport Roll Shop. Our highly trained technicians use ultra precise machines to grind your rolls to the exact specifications required. We check and recheck surface quality using our quality checklist to make sure the job is done right every time. We know that a damaged or misshapen roll means your business loses money, so we take pride in creating the most accurate surface possible.

Precision Accuracy

We use computerized grinding systems and measurement arms to create the most accurate roll based on your specifications. Our technicians are highly trained to return your roll to its original standards for surface quality and roundness. Rockport Roll Shop can even handle custom-shaped rolls if necessary. Our partnerships through CORE’s global network give us access to the latest technology, training, and innovations in the industry.

Inspect and Re-Inspect

Rockport Roll Shop inspects rolls more often than anyone else in the business. Our inspection systems help us detect any underlying bruises, cracks, or flaws that a visual inspection might miss. We check and recheck surface quality using the Purchase Material Request (PMR) from our Customer Specifications and enter them into our Roll Shop Management System which helps us monitor the processing of customer rolls to ensure that our customers specifications are being met. After the entire inspection process is complete, we send every customer a report so they know their roll has been processed to the correct specifications. Download sample specifications and a complete roll process report here to learn more about the details of our inspection process.
