Production Facility

A workshop dedicated to marine propulsion

MAUCOUR operates a 2,130 m² production facility in Saint-Herblain, near Nantes, France, entirely dedicated to the machining of marine propellers and propulsion shafts.

From design to manufacturing

All parts are produced using a combination of CNC and conventional machines, ensuring high precision, tight tolerances and full compliance with applicable marine standards. The facility is structured around five complementary departments.

Machining

Marine propellers up to 3 metres in diameter and propulsion shafts up to 12 metres long, cast or fully CNC-machined.

Capabilities and machine fleet

  • Propellers — up to 3 metres in diameter, larger dimensions available on request, cast or fully CNC-machined.
  • Propulsion shafts — up to 12 metres in length and 230 mm in diameter as standard.

Machine fleet

  • 3 CNC lathes: MICROCUT (6 m between centres), SOMAB and CMZ
  • 2 conventional lathes
  • 1 CNC milling machine (Huron)
  • 2 conventional milling machines
  • 1 broaching machine (LAPOINTE)
  • 1 CNC slotting machine (CAMS)

This machine fleet gives us high flexibility and short lead times, for marine and industrial applications alike.

Boilermaking – Welding

Fabricated and welded assemblies in aluminium, carbon steel, stainless steel and copper alloys, plus complete propeller repair. The workshop is equipped with MIG and TIG welding stations and gas torches.

Polishing – Balancing

Polishing propellers, rudders, brackets and propulsion components calls for extensive know-how. Our teams work with manual and pneumatic grinders in dedicated polishing bays, ensuring high-quality surface finishes and precise balancing.

Quality

All components are inspected and approved prior to shipment by our quality control department, to fully meet customer and marine industry requirements. We operate a computerised propeller inspection system, enabling precise measurements and the issuance of detailed inspection reports.

Warehouse – Storage
