What On Site Machining does
On Site Machining bv (OSM) is a Belgian industrial on-site machining services company founded in 1987 and headquartered in Aartselaar, Belgium. The company specializes in bringing precision machining capabilities directly to customer sites, eliminating the need to dismantle and transport heavy equipment to workshops. OSM operates a fleet of mobile CNC machines capable of shaft machining, drilling, tapping, pipe cutting, turning, flange facing (up to 12m diameter), milling, boring, grinding, thermal lancing, and torquing/tensioning, with precision tolerances up to 0.01mm. The company also maintains a workshop equipped with stationary CNC machines (Anayak HVM 3800, Mondiale Challenger 1300, Mondiale Challenger 76 HTL, Mondiale Challenger BNC-4000 V) for precision component manufacturing, and designs and builds custom mobile machines for project-specific applications, including a proprietary 17m diameter flange machining solution developed for the Orion I crane ship project in 2021.
The company's revenue model is project-based professional services with per-project pricing quoted on scope and complexity, supplemented by a machine rental channel. OSM targets enterprise customers across seven primary verticals: refineries and gas terminals, chemical and petrochemical plants, ship repair and maritime, crane and bridge construction, power plants and energy, steel industry, and food industry. Notable enterprise customers include DEME Offshore, Exxon, ArcelorMittal Belgium, EDR Antwerp Shipyard, and Bergerat Monnoyeur Belgium. The company operates internationally with a claimed worldwide footprint, and all service engineers hold VCA safety certification. Distribution is entirely direct through field service engineers who travel to customer sites, with marketing conducted through a multilingual website (Dutch/English), LinkedIn, Instagram, YouTube, and Facebook. The company is privately held with no disclosed external funding, operating as an independent Belgian private limited company.
