Roller refurbishment – comprehensive services in machining, rework, grinding and polishing

Roller refurbishment in the highest level of precision.

Our refurbishment services result in a perfect roller.

With over 60 years of experience in precision grinding of rotationally symmetrical components you can expect the highest quality in machining, rework, polishing, precision grinding and premium refurbishment services of your rollers.

Calender rollers used for electrode production by battery manufacturers serve as our benchmark. They rely on extremely precise results in position tolerances and finishing to deliver the required performance. With state-of-the-art machinery and in-depth expertise in roller production as well as calendering technologies, we set the standard.

Our North American location in San Antonio, Texas, and the expansion of existing capacities in Germany (Precision Center in Vreden 2024), makes us your partner of choice for roller processing, refurbishment, and repair.

Inspections

During roller inspections we carefully check for damage and wear and carry out a concentricity check. We then prepare a professional inspection report for you.

Cleaning

We disassemble and assemble bearing units and all other components, while taking care of the professional disposal of liquids (such as thermal oil, emulsions etc.) with subsequent rinsing of the rollers.

Rework

We remove a wide variety of coatings such as chrome, ceramics, or tungsten carbide. After recoating, we carry out precision grinding. If necessary, we polish the roller to a mirror finish.

Coating

In addition to common coating processes that we offer, including final precision grinding and polishing, we will be happy to advise you on alternative coatings also.

Roller concepts

It may make sense to rethink established processes for your application. We will be happy to advise you on alternative roller concepts.

Installation

We take care of the installation and commissioning of the reconditioned rollers on-site. Afterwards, you can count on our comprehensive after sales services.
