What Precision Roll Grinders does
Precision Roll Grinders (PRG) is a privately held, family-owned industrial services company founded in 1969 and headquartered in Allentown, Pennsylvania. The company specializes in precision roll grinding, repair, and refurbishment services for manufacturers whose production processes depend on cylindrical rolls and rotating components. PRG operates four manufacturing facilities in the United States (Allentown PA, Carrollton GA, Lewisport KY, and Texarkana AR) and describes itself as the premier large roll and cylindrical shaft grinding company in the Western Hemisphere. The company serves more than fifteen industrial verticals including paper, metals, flooring, food processing, lithium-ion batteries, plastics and film, rubber, nonwovens, cement, ink, chocolate, forest products, and turbine/compressor/wind energy.
PRG's core technology centers on Waldrich-Siegen precision grinding equipment installed in temperature-controlled facilities with shock-absorbing million-pound foundations. The company holds proprietary capabilities in three areas: 3D Hot Grinding, which heats rolls to operating temperatures up to 600°F and creates individual mapping programs for future non-hot regrinding; Roll Armor, a three-layer ceramic/tungsten carbide coating system; and SpecCheck, a 24-point quality inspection process. The stated technical specifications include grinding tolerances as fine as 20 millionths of an inch total indicated runout, surface finishes down to one-quarter micro-inch Ra, and the ability to handle rolls up to 240,000 pounds, 168 inches in diameter, and 600 inches in length. The company is also an authorized distributor of Walzen Irle chilled iron rolls and shells, which provides a new-equipment revenue stream alongside services.
PRG's business model is B2B industrial services sold through direct enterprise field sales. Pricing is quote-based, organized around multi-year contracts and project-based service fees, with emergency and expedited services available. Revenue streams include precision grinding (ambient, hot, and 3D), repair and refurbishment (journal repair, chrome plating, brush electroplating, weld repair, metal spraying, dynamic balancing), complete machine rebuilds for chocolate refiners, ink mills, and coffee grinders, and new roll and component sales. Distribution is via direct ship-to-facility: customers transport heavy rolls to the nearest of PRG's four US plants and receive them back after service. The company does not publicly disclose revenue.
