Precision Grinding Services in Chicago, IL

Parkway-Kew Corporation supports precision grinding for large industrial wear components, including wire drawing blocks, coated rolls, pulleys, plungers, and heavy process parts. Capabilities are especially suited for components that need restored geometry after coating, rebuilding, or hardfacing. The team also pairs grinding with CNC turning, manual turning, CNC milling, and wear-resistant coating services when a complete repair is required.

Large diameter grinding capabilities extend up to 65 inches in diameter and 12 feet in length. This makes the service a strong fit for oversized industrial components that cannot be handled by smaller machine shops. Parkway-Kew Corporation also supports machining capabilities up to 72 inches in diameter, helping customers coordinate coating, turning, milling, and finishing work through one experienced source.

Yes. Grinding is often used alongside wear-resistant coatings such as tungsten carbide, chrome oxide, ceramic, nickel chrome alloys, and other hard surfacing options. After coating or rebuilding, precision finishing helps restore the part’s working surface, diameter, and concentricity. This integrated approach can improve wear life, corrosion resistance, and operating consistency for high-load industrial applications.

Parkway-Kew Corporation serves demanding industrial markets including wire mills, oil and gas fracking operations, shipping terminals, heavy equipment manufacturers, earth-moving equipment users, and container ship loading and unloading operations. Chicago-area manufacturers with high-wear production equipment often need the same combination of durable coatings, large-part handling, and precision finishing to reduce downtime and extend component service life.

The Restore & Grind process is a proprietary repair method developed for wire drawing blocks. Instead of grinding all the way down to the deepest groove and removing substantial usable coating, Parkway-Kew Corporation fills only the drawline area and blends it into the original coating. Because PK coatings are applied with enhanced thickness, lower-cost repairs may be possible multiple times before a full recoating is needed.

Turnaround depends on the component size, coating condition, material, inspection requirements, and whether machining or rebuilding is needed before grinding. Parkway-Kew Corporation’s standard availability is Monday through Friday, 8:00 am to 5:00 pm. Providing drawings, photos, dimensions, coating history, and wear details early helps the team review the job efficiently and plan the correct repair sequence.

Precision grinding can reduce replacement costs when a worn component still has enough usable base material or coating to be restored. Services such as large diameter grinding, rebuilding, and Restore & Grind can return critical surfaces to working condition while preserving valuable coating where possible. This can extend component life, reduce changeouts, and help plants avoid unnecessary new-part purchases.

To request a quote, share the part type, diameter, length, material, coating requirements, current wear condition, desired finish, and any drawings or tolerance requirements. For rebuilt components, include information about how the part is held or loaded in service. Parkway-Kew Corporation uses these details to recommend the proper grinding, coating, machining, or rebuilding solution for the application.
