Advanced industrial facilities

French quality

Located in La Seyne-sur-mer, in the South of France, with direct sea access, CNIM Systèmes Industriels (CSI) facilities comprise more than 60,000 sq of workshops and tools dedicated to large and complex equipment & systems manufacturing.

CSI manufactures according to the most demanding standards and codes of the industry (RCCM, RCCMX, ASME, CODAP, ESPN ...):






Large & complex machining

Vertical & horizontal turning machines

CSI turning centers can machine parts up to 3.5 m long and 50 tons.

In September 2018, CSI commissioned its 5th turning machine, which now manufactures the thrusters of the Ariane 6 launcher.

Large & high speed milling machines

Among its large and high speed machining centers, CSI owns the INNSE Berardi milling machine equipped with a double gantry and a linear motor. Installed in an air-conditioned workshop to the degree, its large dimensions are suitable for large parts measuring up to 36 m long and 10 m wide.

CSI also has JOBS three high-speed miling centers.

Large machining - fabrication of ITER radial plates

Boring machines adapted to complex geometries

With its 5-axis head and rotative table supporting more than 40 tons, the PAMA SPEEDRAM 2000 machine is one of the boring machines that enables CSI teams to perform very high-precision machining of large parts with complex and varied geometries.

Recent investments

To meet the manufacturing requirements of the aeronautics and space sectors, CNIM Systèmes Industriels is currently commissionning a new production line using flow-forming technology.

For the semiconductor market, CSI installed three new high-speed milling centers to produce complex aluminum structures, with a flatness accuracy of 50 μm over 5 m.

High-performance welding

Strong experience in electron beam welding

CNIM Systèmes Industriels has more than 30 years of experience in electron beam welding of various materials, including materials that are known to be difficult to weld, such as AG3NET or Inox.

CSI also masters all manual (TIG, MIG) and automatic welding technologies (TIG, TIG Narrow Gap, MIG, Orbital).

Large size clean room

Cleanroom assembly

CNIM Systèmes Industriels has a 220 sqm ISO 6 cleanroom for large parts (up to 5 m high) cleaning, assembling, integrating and packaging), under high cleanliness constraints. This cleanroom is in service since 2012.

This cleanroom allows us to meet the requirements of our customers for maintaining cleanliness during the manufacture of high-performance systems and equipment. This is the case, for example, in the manufacture of systems for frequency conversion and focusing of high-power lasers.
