Precision Roll Grinding & Balancing

Western Machine Works grinds and balances all paper machine roll and cover types. Pre-grind and post grind profiles are taken using our customized Pro-Mic Roll Measurement System. Pre-grind profiles are analyzed to provide feedback to our customers regarding operational wear, or loading issues that can be corrected to optimize performance and extend grind cycle frequencies. A Gem Super Finisher is also utilized to assure consistent surface finish requirements.

ISO 21940 G Grade specifications are used for balancing rolls on our SCHENK balancing machine. Most paper machine rolls are balanced at G1.0 specifications with some sensitive rolls being balanced to G.1 specifications. Western Machine Works also offers a unique service of checking baseline vibration analysis of bearings to minimize the chance of a defective bearing being placed in service.

Transportation Services

Western Machine Works offers specialized transportation services to ensure that your rolls are picked up and delivered in a safe and economical manner. We understand how critical your rolls are so we have dedicated drivers who are trained to transport rolls using specialized equipment and processes that secure and protect them during transportation.

WMW offers a full fleet of trucks including pickups, flatbed, and a semi tractor with a 40-foot trailer. Our team can also fabricate custom brackets and holding equipment for your rolls so they are transported securely and are delivered at their optimum quality.

New Roll Manufacture

We put our decades of experience in repairing and maintaining rolls into our engineered new roll manufacturing process. Western Machine Works designs and manufactures new rolls including press rolls, wire rolls, felt rolls, and reel spools. We understand that most replacement rolls operate at parameters drastically above their original design. Western Machine Works will determine today’s operating environment and incorporate it into a suitable design for the future.
