Special mechanical parts - Precision turning and machining

Today, we produce the fasteners of tomorrow
From design to mass production of your parts
Co-design and development
Working closely with LGC's design engineers, you will define the project's specifications, technical requirements and constraints.
  • Feasibility checks using the FMEA tool, which is used to analyze failure modes, their effects and criticality.
Prototyping and Testing
Once the concept has been approved, the project team creates physical prototypes using a 3D machine and simulation software such as SolidWorks Premium and Spacerclaim.

  • Production of initial samples in medium series, and validation of production with PPAPs in accordance with IATF 16949.
Industrialization and Production
The production process is validated according to the production control plan drawn up by a multi-disciplinary team. 

  • Development of detailed production processes according to the APQP quality process
Assessment and Improvement
After 3 to 6 months of series production, an assessment based on the criteria required by IATF 16949 verifies 100% project conformity.
  • Collection and analysis of production data to identify trends and variations. 3PPM in 2023.

Precision turning and machining: from raw materials to the mechanical part of your dreams

The machining of mechanical parts is a manufacturing process involving the selective removal of material to transform a raw part into a special part with very specific dimensions and shapes.

There are various machining processes, and at LGC we use CNC machining processes such as : 

  • The shoot
  • Milling
  • Drilling
  • Bar turning...

Bar turningis a state-of-the-art machining process that has been at the heart of our industry since it first appeared in the 18th century. Over time, it has evolved into modern bar turning thanks to the introduction of increasingly high-performance and precise CNC machining centres.

Today, bar turning has become an indispensable process in the creation of precision mechanical parts, found in many cutting-edge sectors requiring high-quality parts. 

  • Aeronautics
  • Automotive
  • Electronics...

Bar turning is the ideal solution for obtaining special mechanical parts with precise shapes and impeccable finishes. 

At LGC industries, we're proud of our expertise in bar turning, which we've been integrating into our co-design of special mechanical parts for over 80 years. 

Our commitment to excellence enables us to consistently exceed our customers' expectations. 

What's more, we invest in the latest CNC machining equipment to stay at the cutting edge of innovation and guarantee ever-better results.

Different machining techniques for custom mechanical parts

The turning and machining of your mechanical parts is made possible by our industrial facilities specialized in the design and production of parts by material removal.

Our industrial facilities include recent machine with a large number of CNC machining centres:

  • 24 CNC multispindle lathes
  • 45 rpm CNC escomatic
  • 42 canneleuses
  • 8 plunge and thread grinders
  • 2 cold heading machines
  • 3 automatic packaging lines
  • 6 optical sorting and metrology machines
  • 2 robotized assembly lines
  • 1 tribofinishing and polishing unit
