Koebrugge Metaal Bewerking B.V.

What Koebrugge Metaal Bewerking B.V. does

Koebrugge Metaal Bewerking B.V. is a Dutch precision machining contract manufacturer headquartered in Hengevelde, Overijssel, producing high-tolerance metal components for OEM customers in semiconductor, medical device, defense, aviation, food-grade, and optics industries. Founded in 1990 and operating today with roughly seven employees, the firm delivers parts ranging from Ø 0.19 mm to Ø 600 mm at tolerances down to 2 µm using a modern park of 3-, 4-, and 5-axis CNC turning and milling machines, wire EDM (draadvonken) for complex geometries in hard materials, and a Grade 2 cleanroom (ISO 14644-1 Class 6) for contamination-controlled assembly. Material coverage spans stainless steels, non-ferrous alloys, titanium, nickel-based superalloys (e.g., Inconel), engineering plastics including PEEK, and ceramics.

The firm is qualified for regulated OEM supply chains, holding ISO 9001 for general quality management, ISO 13485 for medical device manufacturing, and ITAR-ready file-transfer capability for defense trade. Process discipline is supported by inline coordinate measuring machine (CMM) corrections during machining, SPC reporting, full traceability, and Digital Twin/CAM-simulation workflows that allow virtual trial runs to reduce setup time and scrap. Surface treatments (anodizing, passivating, micro-bead blasting) and clean packaging are integrated under one roof, enabling end-to-end delivery from prototype through series production.

Commercially, Koebrugge operates a quote-based, project-priced B2B model with multi-year contracts, selling directly to enterprise OEMs via account-based field sales led by Director Gert-Jan Keupers and Operations Manager Christiaan Spijkerman. The firm is a member of StM Precision Group, a network of Twente-region precision machining specialists that provides combined capacity and complementary capabilities while preserving each member's independent identity. Revenue is not publicly disclosed and the firm has no venture, private equity, or public shareholders indicated.

Direct peers

• Mefion Instrumentmakerij: StM Precision Group partner in Ommen focused on instrument making. Highly comparable in scale, geography, and customer profile (high-precision OEM work in regulated industries).
• RM Precision: Sister company within the StM Precision Group, located in Nijverdal. Provides specialized precision machining and serves as direct capacity backup for KMB on shared customer programs — most directly comparable peer in the same network.
• Vandervegt Fijnmetaal: Fine-metal precision specialist within StM Precision Group in Raalte. Overlapping customer base and capability profile, especially for fijnmechanische components in similar size and tolerance ranges.
• Hembrug Machine Tools: Dutch manufacturer of ultra-precision turning machines and a contract precision machining provider. Closest national peer serving similar high-tolerance, single-piece and small-series work for European OEMs.

Broad incumbents

• INDEX-Werke: German precision turning and machining center manufacturer with a strong contract manufacturing arm. Comparable in precision and OEM customer base, but a much larger established player with full machine-tool product lines.
• Trumpf: German technology leader in machine tools and laser/precision manufacturing with broad European presence. Overlaps with KMB in precision sheet and parts production for industrial customers, though vastly larger and more diversified.
• Mikron Tool: Swiss-headquartered precision tooling and machining specialist with broader European footprint. Comparable in micron-level precision and regulated-industry focus, but operates at substantially larger scale.
• Schaublin: Swiss high-precision turning and machining specialist serving aerospace, medical, and watchmaking. Similar ultra-precision positioning with a broader geographic and product footprint.
• EMUG-Werk / EMUGE-FRANKEN: German precision tooling and machining solutions provider. Adjacent in precision manufacturing for demanding industries but primarily a tooling manufacturer rather than a contract precision shop.
• Tornos: Swiss manufacturer of Swiss-type turning machines with a precision subcontracting business. Comparable on tight-tolerance turning for medical and industrial OEMs, but at substantially greater scale and brand recognition.
