About the company
United Grinding North America, Inc., based in Miamisburg, Ohio, supplies precision grinding machinery, replacement parts, preventive maintenance, and repair services to federal agencies as a prime contractor (97% of recent awards), competing predominantly full-and-open without set-aside designations, though small business designations recur on a minority of Naval awards. The company is a for-profit corporate entity classified primarily under NAICS 424720 (Industrial Machinery and Equipment Merchant Wholesalers) and 331512 (Machine Tool Manufacturing), with a named subsidiary, United Machining North America LLC.
United Grinding's federal footprint is heavily concentrated with the U.S. Mint, which accounts for 104 of 140 total awards (74% of the portfolio) and $16.5 million in combined potential value (88% of the vendor's total). The Mint work consists almost entirely of purchase orders for Studer and Walter grinding machine supplies, preventive maintenance, and repair services performed at the Mint's facilities, primarily in support of coin and medal production operations. Naval Sea Systems Command ranks second with 7 awards ($286 thousand) covering Walter grinder supply and maintenance at Naval Submarine Base New London, including a $191.6 thousand small business set-aside for a three-year Walter grinder maintenance contract running through September 2027. Naval Air Systems Command has issued 4 awards ($55 thousand) for Walter axis installation and testing work in Jacksonville, Florida. The Department of the Army and Department of the Navy Pacific Fleet Forces round out the agency customer base with smaller volumes. Thirteen distinct federal agencies have issued awards across the recent period.
Activity has contracted significantly — from a historical pattern that included multi-year periods with one award per year to only one award in 2026 (as of early June), two in 2025, and three in 2024 — suggesting either a decline in Mint procurement volume or a shift in the Mint's contracting approach. Four awards valued at $780 thousand reach ultimate completion within the next twenty-four months and face recompete exposure. United Grinding places five named parent vehicles, including two multi-year indefinite delivery contracts (TMHQ12C0047 with 10 task orders, $247 thousand, and TMHQ14C0059 with 1 task order, $927 thousand) but derives the majority of work from single purchase orders rather than IDIQs or BPAs. The vendor holds a minimal subcontractor footprint — three recent sub awards under Leidos, RTX Corporation, and Lockheed Martin for critical minerals research support, F135 engine control unit design, and GMLRS rocket production tooling grinding, respectively. The combined obligated value across all 140 awards stands at $12.2 million against a combined potential value of $18.6 million (65% obligated rate), reflecting a high proportion of completed transactional work.
