Compass Precision

What Compass Precision does

Compass Precision, LLC is a privately held, PE-backed holding company that operates a roll-up platform of precision CNC machining shops serving mission-critical applications. Founded in October 2019 when Main Street Capital Holdings, LLC simultaneously acquired Advanced Machining & Tooling, Quality Products & Machine, and Tri-Tec Industries in the Charlotte, NC area, the company has grown to 11 operating companies across approximately 200,000 square feet of US manufacturing space, with roughly 180 employees. Each operating company maintains specialized capabilities — 5-axis milling, multi-tasking mill/turn, EDM, Swiss screw machining, lights-out automated production, and welding/fabrication — and retains autonomous operating leadership while drawing on shared corporate resources for capital investment, ERP rollouts, and management best practices.

The platform's core service is custom precision metal component manufacturing in prototype through large production volumes, with a deliberate focus on difficult-to-machine materials (titanium, Inconel, Monel, nickel-based alloys, tool steels) and tight-tolerance geometries that most standalone shops will not quote. The equipment base of 28 five-axis vertical mills, 61 three/four-axis vertical mills, 16 multi-tasking mill/turn machines, 23 Swiss screw machines, and 17 EDM machines supports maximum part envelopes up to 120 inches by 40 inches by 30 inches. Multiple facilities hold AS9100D, ISO 9001:2015, ITAR, CMMC, and AWS certifications, qualifying the platform for aerospace, defense, space, medical, semiconductor, power generation, industrial automation, and telecommunications customers including NASA/Lockheed Martin, SpaceX, and gas turbine OEMs.

Revenue is generated through quote-based, project-priced contracts for custom parts rather than catalog or subscription pricing. The go-to-market is direct enterprise field sales led by VP of Sales Jim Miller, who functions as a "point guard" routing inbound opportunities to the operating company best matched to the customer's capability, material, and tolerance requirements. Distribution is exclusively direct B2B; the company does not use third-party channels, e-commerce, or distributors. Marketing relies on thought leadership content (a podcast, YouTube channel, technical paper library, and employee recognition programs) to build inbound demand and recruit scarce CNC machining talent. Acquisitions have been the dominant growth lever, with eight add-on transactions closed between 2020 and 2026 under Main Street Capital's continued sponsorship.

Core offering

Compass Precision is a holding company that, through 11 operating companies, manufactures custom precision metal components in prototype, small, medium, and large production volumes. Core services include 5-axis CNC milling, multi-tasking mill/turn, Swiss screw machining, EDM, and sheet metal fabrication/welding, with deep expertise in difficult-to-machine alloys such as titanium, Inconel, Monel, and nickel-based superalloys. Customers are enterprise OEMs and Tier suppliers in aerospace, defense, space, medical, semiconductor, power generation, industrial automation, and telecommunications requiring tight tolerances, demanding geometries, and mission-critical reliability.

Product overview

Compass Precision operates as a holding company with a platform architecture comprising 11 distinct operating companies that function autonomously while sharing resources, best practices, and customer access. The portfolio includes three core brands founded in 2019 (Advanced Machining & Tooling, Quality Products & Machine, and Tri-Tec Industries), seven acquired precision machining specialists (Gray Manufacturing Technologies, Douglas Machining Services, R&D Machine, Strom Manufacturing, Bergeron Machine, Pocasset Machine, and Accu-Tool), plus Trutron Corporation. Each operating company maintains specialized capabilities—5-axis machining, Swiss machining, mill/turn, EDM, lights-out automated production, and welding/fabrication—serving aerospace, defense, space, medical, semiconductor, industrial automation, and power generation markets. The parent company provides capital investment, equipment upgrades, ERP systems, financial controls, and management expertise while allowing autonomous operation. The portfolio is anchored by Quality Products & Machine (largest company) and supported by complementary capabilities across the network, enabling cross-selling and resource sharing among operating units.

Emerging players

• Duncan Machine Products: Independent precision machining shop specializing in complex CNC milled and turned components for aerospace, defense, medical, and industrial customers. Directly comparable in capability mix and customer profile but at smaller scale and without the platform/roll-up structure of Compass.

Broad incumbents

• Precision Castparts Corp: Berkshire Hathaway-owned large-scale manufacturer of complex metal components and assemblies for aerospace, power, and industrial markets. Overlaps in mission-critical aerospace precision components but operates at vastly larger scale as a fully integrated supplier versus Compass's job-shop network model.
• ATI Inc. Public specialty materials and components producer serving aerospace, defense, and industrial markets with titanium, nickel-based alloys, and precision-machined parts. Overlaps with Compass on hard-to-machine materials expertise and aerospace/defense customer base but operates upstream in materials production.
• Phillips Corporation: Private industrial manufacturer with precision machining and fabrication capabilities serving aerospace, defense, and industrial markets. Comparable customer base and mission-critical focus, but a larger and more diversified industrial portfolio than Compass's pure-play precision machining network.

Direct peers

• Hubs: Protolabs-owned on-demand manufacturing platform offering CNC machining, injection molding, and 3D printing services. Comparable as a precision contract machining services provider with a global partner network serving aerospace, robotics, and industrial automation customers.
• Re:Build Manufacturing: Private PE-backed manufacturing roll-up acquiring US-based precision manufacturing businesses across CNC machining, composites, and metal fabrication. Most structurally comparable peer—same PE-backed acquisition strategy, similar target profile of independent job shops, and similar emphasis on US-based reshoring.
• Protolabs: Public digital manufacturer offering CNC machining, injection molding, sheet metal, and 3D printing with quick-turn production. Comparable as a precision contract machining services provider serving aerospace, medical, and industrial customers; Protolabs emphasizes automated quoting and digital workflow versus Compass's white-glove field sales model.
• Fictiv: Private digital manufacturing platform that connects customers to vetted CNC machining and fabrication partners. Directly comparable business model serving precision machined components for similar end markets including aerospace, robotics, and medical devices.
• Xometry: Public on-demand manufacturing marketplace offering CNC machining, 3D printing, and injection molding services. Directly comparable as a precision contract machining services provider serving aerospace, defense, medical, and industrial customers, though Compass focuses on higher-complexity mission-critical parts while Xometry scales via marketplace model.

Regional players

• Frisa Industries: Mexico-based precision machining and forging manufacturer serving aerospace, industrial, and oil and gas markets. Comparable in precision component manufacturing for aerospace customers but operates primarily in Mexico/US-Mexico cross-border manufacturing rather than purely US-domestic production.
