What RB 10 does

Randbright is a privately held, family-owned US manufacturer of cylindrical (centerless) finishing machines used to shape and finish the outside diameter of metal and composite parts. Founded in 1972 in New Berlin, Wisconsin by the Randall brothers (Greg and Steve) alongside their father John, the company is now headquartered at 11123 89th Ave N in Maple Grove, Minnesota. Its product line spans four models: the RB 10 (1 HP compact benchtop unit for light-duty, 1-inch diameter parts), the RB 60 (5 HP wet/dry deburring and finishing for up to 6-inch parts), the RB 80 (10 HP, up to 8-inch diameter parts, configurable from one to four heads), and the RB 120 (15 HP heavy-duty unit handling up to 12-inch parts with up to four-head single-pass flow). The machines use abrasive belts, brushes, and Scotch-Brite wheels in through-feed, end-feed, and in-feed configurations, with optional wet-cooling, automated loading/unloading, and touchscreen controls.

The company's revenue model is direct hardware sales through a quote-based sales motion, with each machine configured and calibrated to the customer's manufacturing footprint using an in-house demo lab. Pricing is not publicly disclosed; customers engage via request-a-quote forms segmented into Sales, Service, and Parts inquiries. Go-to-market is sales-led with direct customer engagement, supported by product pages, an engineering blog, and published case studies. The company operates within a broader brand family that includes sister brand Timesavers (flat finishing) and InCompass (manufactured growth solutions), and maintains a long-standing distribution and component partnership with 3M for abrasive materials.

Randbright serves industrial manufacturers across four primary verticals: automotive (engine components, drive shafts, brake and transmission parts), food service (food-grade tanks and beverage dispensers), marine fixtures (yacht hardware and corrosion-resistant marine components), and quality tanks (pressure vessels). Named enterprise customers disclosed in case studies include Dana Incorporated, Fireaway, and Phoenix Stainless, with use cases emphasizing throughput gains, footprint reduction, and consistent surface finish on safety-critical parts. The company continues to manufacture in the USA using domestic labor and components.

Core offering

Randbright designs and manufactures cylindrical (centerless) finishing machines for metalworking, including the RB 10 bench top unit, RB 60 mid-range wet/dry machines, and the RB 80 and RB 120 large-diameter dry/wet series. Equipment is configured per customer specifications and sold direct to industrial manufacturers for deburring, finishing, polishing, and OD grinding of cylindrical metal and composite parts.

Product overview

Randbright manufactures cylindrical (centerless) finishing machines for metalworking industries. The product line consists of four models: RB 10 (compact benchtop unit for light-duty applications), RB 60 (mid-range wet/dry deburring and finishing), RB 80 (large diameter wet/dry finishing), and RB 120 (heavy-duty large diameter wet/dry finishing). These machines use abrasive belts, brushes, and Scotch-Brite wheels to perform cylindrical finishing on metal parts. The portfolio ranges from 1 HP benchtop units handling 1" diameter parts to 15 HP industrial machines handling up to 12" diameter parts, with options for wet grinding (with coolant systems and paper bed filters) and dry grinding (with dust collection).

Products and services

• RB 10 The RB 10 Dry is a compact, portable, bench top cylindrical finishing machine designed for light-duty applications in job shops, small businesses, and light manufacturing environments. It uses non-woven abrasive wheels and brushes to deburr, finish, and polish small-diameter cylindrical metal parts, targeting customers requiring entry-level or low-volume cylindrical finishing without large industrial footprints.
• RB 60 The RB 60 Wet and Dry Series are centerless, outside diameter deburring and finishing machines ideal for a large variety of cylindrical parts using abrasive belts and finishing wheels. Mid-range industrial machine targeting manufacturers requiring wet or dry grinding configurations for moderate-volume cylindrical part production.
• RB 80 The RB 80 Dry/Wet Series machines are designed for large diameter parts and are configurable from one to four heads for single-pass flow. Targets high-volume industrial manufacturers requiring robust cylindrical finishing for larger components such as automotive parts, fire suppression cylinders, and stainless steel components.
• RB 120 The RB 120 Dry/Wet Series machines are the highest-capacity Randbright machines, designed for large diameter parts and available in one to four head configurations for single-pass flow. Targets heavy-duty industrial applications including large pressure vessels, quality tanks, and oversized cylindrical components.
