Precision turning and machining: from raw material to the ideal mechanical part

Machining parts is a manufacturing process involving selective removal of material in order to transform a raw part into a custom part, with very specific dimensions and shapes.

There are various machining processes. Here at LGC, we use CNC (numerical control machining) processes such as:

  • Turning
  • Milling
  • Drilling
  • Bar turning

Bar turning is an advanced machining process that has been at the heart of our industry since its beginnings in the 18th century. Over time, it has evolved into modern bar turning with the advent of increasingly efficient and accurate CNC machines.

Today, bar turning has become an essential process in creating mechanical precision parts for various cutting-edge sectors requiring high quality parts, such as:

  • Aeronautics
  • Automotive
  • Electronics

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

At LGC Industries, we are proud of our expertise in bar turning, which we have put at the heart of our co-designing of special mechanical parts for over 80 years.

Our commitment to excellence allows us to continuously surpass our customers' expectations.

Moreover, we are investing in new CNC machines in order to remain at the forefront of innovation and to guarantee increasingly efficient results.

The different ways of machining custom mechanical parts

Turning and machining your mechanical parts is made possible thanks to our industrial facilities specialised in the design and production of parts by removing material.

These industrial facilities are made up of recent machines, with numerous CNC machines:

  • 24 multi-spindle CNC lathes
  • 45 Escomatic CNC lathes
  • 42 fluting machines
  • 8 plunging and threading grinding machines
  • 2 cold forming machines
  • 3 automatic packaging lines
  • 6 optical sorting and metrology machines
  • 2 robotic assembly lines
  • 1 vibratory finishing and polishing unit

Machining and bar turning at the heart of co-design

At LGC Industries, we specialise in the design and manufacturing of made-to-measure special mechanical parts and fasteners.

Our aim is to meet your specific fastening requirements by working with you throughout the process.

We strongly believe in the concept of co-designing with our customers.

We understand that each project is unique, which is why we work closely with you in order to develop and manufacture custom mechanical parts that will perfectly meet your needs in terms of dimensions, materials and performance.

Quality is at the heart of what we do.

All of our custom-made special parts are manufactured according to the highest quality standards to ensure their durability and reliability.

  • ISO 9001
  • ISO 14001
  • IATF 16948

We make it our priority to provide you with high-quality products.

As an environmentally responsible company, we also attach great importance to the eco-design of our bespoke special parts.

We are committed to minimising our environmental impact by using recyclable and sustainable materials as much as possible. In addition to this, we are implementing measures to reduce production waste in order to preserve our planet for future generations.
