What C & B Machinery does
C & B Machinery is a Michigan-based builder of high-precision face grinding machines founded in 1980 by Joe Parker and headquartered in the Brighton/New Hudson, Michigan area. The company designs, manufactures, and supports Double Disc Grinding Machines (horizontal and vertical configurations with swing arm, rotary, reciprocator, park & grind, and through feed tooling options) and Clamp Bore Face Grinders (single and double spindle), and is distinguished by its proprietary non-coplanar/step connecting rod grinding process first commercialized for GM's Chevy Volt program. All machines, including tooling, fixtures, controls, and lubrication systems, are designed and built in-house at its ISO 9001:2015 certified facility, and the company is an Authorized Fanuc Robotics System Integrator for automation cells.
The business generates revenue across six streams: new machine sales (capital equipment), machine rebuilds and re-engineering of legacy Besly, Gardner, Giustina, and Mattison equipment, spindle rebuild services, automation and control retrofits (Allen Bradley, Siemens, Fanuc), spare parts and tooling (including its premium 7-point dresser diamond), and prototype/production grinding services. Pricing is quote-based with multi-year contracts; sales run through direct enterprise field sales plus international sales representatives, targeting automotive OEMs and Tier 1 suppliers as the primary vertical, with secondary presence in aerospace, hand tools, bearings, oil & gas, defense, and heavy equipment.
The company has been owned by Orbitform since August 17, 2020, operating as a separate entity alongside sister companies Orbitform (fastening, forming, assembly) and Wardcraft Conveyors; Bill Tulpa serves as President, Jeff Allen as VP of Operations (25+ year tenure), with Fabrizio Tarara and Chris Cox as additional VPs. Notable commercial wins include Ford, GM, Chrysler preferred/Tier 1 supplier status, Allison Transmission grinding cells delivered to India and U.S. facilities, Klein Tools plier grinding, Honeywell aerospace brake pad work, and a 2025 wave of major orders spanning automotive, aerospace, and Tier 1 retrofit work.
