Bar turning
Bar turning is a manufacturing process for precision parts, mainly used in industry. It consists of machining cylindrical parts by turning or milling them from bars or rings using material removal. Bar turning enables the production of complex, high-precision parts used in numerous sectors such as automotive, aerospace and electronics. Our cam-type lathes and high-speed CNC lathes enable us to work with hundredths precision on medium and large production runs.

Precision turning and machining: from prototype to mass production

Bar turning is a cutting-edge machining process which consists in giving a precise shape to parts by removing material. This process, at the heart of our industry, has been in constant evolution since it first appeared in the 18th century. Today, it has evolved into modern bar turning thanks to the arrival of increasingly high-performance and precise numerically-controlled machines.

Bar turning has become an essential process in the creation of precision mechanical parts in many high-tech sectors.

At LGC industries, we've been perfecting the art of bar turning for over 80 years, surpassing our customers' expectations through our commitment to excellence and the use of new, state-of-the-art machinery.

What is bar turning of mechanical parts?

Bar turning is an innovative machining technique that enables the production of high-quality custom parts. With growing demand in high-tech sectors, bar turning has become an imperative for meeting ever-changing needs.

Bar turning, an industrial process used to create turned or "revolutionary" mechanical parts such as pinsnozzles, bolts and much more. Thanks to this precise turning technique, material is carefully removed to transform a raw part into a specific part using a high-performance cutting tool.

Bar turning is made possible by our industrial facilities specialized in the design and production of parts by material removal.

Industrial facilities that translate into a machine park comprising :

  • 24 multispindle lathes
  • 45 rpm 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

The advantages of bar turning

⚙️ Productivity and adaptability: our bar turning machines can machine parts from one-offs to very large quantities, all within very short lead times.

🔎 Quality and efficiency: screw-cutting machines offer precise dimensions with impeccable finishes, thanks to their extreme precision.

💶 Material and cost savings: workpieces are continuously machined in the machine, which considerably reduces the amount of swarf.

♻️ Ecology, eco-design LGC: we recycle 86% of our waste (such as oil and swarf escaping during bar turning), thanks in particular to our swarf wringer machine.

What is machining of mechanical parts?

Like bar turning, machining is an industrial method for shaping a part by removing material. Using a machine tool, it is possible to give a raw part the desired shape and dimensions. With two movements - cutting and feeding - it is possible to control the removal of material with extreme precision, and thus obtain highly accurate workpieces. Machining is the set of techniques used to design, cut and shape the part to give it its final appearance (dimensions, rendering and surfaces).

There are a multitude of machining processes, such as conventional milling, turning, drilling, reaming...

The choice of technique depends on both the materials used and your needs.
