What Busch Precision does

Busch Precision, Inc. is a privately held precision machining and contract manufacturing firm founded in 1907 by master machinist Julius C. Busch in Milwaukee, Wisconsin. The company operates from a 140,000-square-foot facility at 8200 N. Faulkner Road (since 1989) with a secondary office in Hartford, Wisconsin, and runs an ISO 9001:2008-certified operation. It is led by President and CEO Michael A. Mallwitz.

The company delivers four integrated service streams: (1) precision machining and contract manufacturing for large components up to 180 inches in diameter and 58,000 lbs with tolerances as tight as .0001 inch, leveraging Giddings & Lewis boring bars, vertical turning centers, surface grinders, and a full heavy-lift crane infrastructure; (2) machinery repair and maintenance, including CNC retrofitting (Fanuc, Siemens), PLC upgrades, machine tool service/repair, and a three-phase preventive maintenance program; (3) precision tooling products and NIST-traceable recalibration (angle plates, parallels, straight edges, surface plates, V-blocks); and (4) die cast machine components and replacement parts for zinc, aluminum, and magnesium die casting operations. Diagnostic capability rests on Renishaw QC20-W wireless ballbar systems and Schenck SmartBalancers, with hand scraping as a proprietary precision alignment technique. The 2014 acquisition of Maintenance Service Corp.'s machine tool repair and CNC retrofitting lines roughly tripled its capability count from 300 to 800.

Commercially, Busch Precision runs a quote-based, direct-sales model with customers requesting proposals through dedicated RFQ forms for each service line, supported by phone sales, on-site consultations, and an annual Machining & Maintenance Expo at its headquarters. Marketing is anchored in regional trade show participation (WIMTS), social media presence across LinkedIn, Facebook, YouTube, and Twitter, and earned media in trade publications such as Cutting Tool Engineering. Revenue is generated primarily through professional services (contract manufacturing, repair, and maintenance contracts) with one-time/hardware sales for tooling and die cast components; the company does not disclose pricing publicly and operates on multi-year contract cadences for its enterprise accounts in aerospace, construction equipment, agriculture, mining, military, energy, transportation, paper, and water.
