From design to serial production of your parts
Co-Design and Development
1
In close collaboration with the engineers of the LGC design office, you will define the specifications, technical requirements and constraints of the project.
- Feasibility control using the FMEA tool, which is used to analyze failure modes, their effects and their criticality.
Prototyping and Testing
2
Once the concept is approved, the project team creates physical prototypes using a 3D machine and simulation software such as SolidWorks Premium, Spacerclaim.
- Manufacture of initial samples in medium series, and validation of production with PPAP according to the IATF 16949 standard.
Industrialization and Production
3
The serial transition is carried out according to the validated process according to the production control plan written by a multidisciplinary team.
- Development of detailed production processes according to the APQP quality process
Assessment and Improvement
4
After 3 to 6 months of series production, an evaluation based on the criteria required by the IATF 16949 standard verifies the conformity of the project at 100%.
- Collection and analysis of production data to identify trends and variations. 3PPM in 2023.

Optimize your assemblies with a rectified socket
The sockets rectified, which is commonly called”positioning socket or centering socket” play an essential role in mechanics and industrial assembly. They guarantee the precise positioning of the components, thus reducing the risk of deformation of the parts or of uncontrolled movement. These small positioning elements are often overlooked, which may explain in some cases the decline in the overall performance of a mechanism.
La rectified socket or centering socket turns out to be the jewel of the assembly. The rectified socket ensures perfect alignment of the parts, thus eliminating discrepancies and unwanted friction. Frequently used in complex mechanical systems, this small cylindrical part will become the keystone of the precision of your assemblies.
What is a rectified socket?
Les rectified centering sleeves are extremely precise cylindrical assembly elements designed specifically to ensure the precise centering and positioning of 2 components in an assembly.
Their innovative design prevents any risk of entanglement, which is essential for automated assemblies. Thanks to our specialized production resources, we guarantee a quality level close to zero defects, 0 PPM.
Unlike a pin or a centering pin, the ground socket can accommodate a through screw, thus offering greater flexibility in applications.
How are LGC ground sockets made?
There are two different methods for creating a socket
From pin to ground socket
It is possible to start from a solid material that has been machined in order to arrive at a shape of pin. In this specific case, it is necessary to drill a pin to make it hollow, this is called a bore, which complicates the process both financially and technically and environmentally.
From the tube to the rectified socket
In a second case, it is possible to make a positioning socket starting from a tube.
The use of a tube is highly recommended because it perfectly meets all criteria (precision, price, quality and also carbon footprint).
That's the technique we use at LGC.
The first step in making a socket is cutting the raw material.
The raw material is in the form of long, hollow tubes.
The material and the diameter depend on the desired final part.
The tube enters a machine which cuts it to the desired length.
The socket can be further machined with specialized machines.
For example, chamfers may be required or finishes on the material may be applied.
The socket then goes through a stage of rectification.
A roller presses the parts against a grinding wheel rotating at high speed.
It is the wheel that, by abrasion, will modify the diameter of the part to reach precise tolerances of a few microns (~5-6 μm).
What are the advantages of using a rectified socket?
- Dimensional accuracy: a rectified socket guarantees impeccable dimensional accuracy. By creating a uniform space between the components, the rectified socket eliminates potential errors associated with differences in dimensions or alignments between 2 parts.
- Structural stability: the rectified cylindrical socket, with its sturdy shape, provides exceptional structural stability. It is resistant to vibrations and mechanical loads, ensuring optimal performance under demanding conditions. This is why we find almost all the engines of our vehicles.
- Reduction of friction: thanks to its intelligent design and the grinding process, the ground bushing minimizes friction between moving parts. This results in reduced wear and extended component life.
