Processes

The processes we use

In addition to producing our customers’ components on their behalf in accordance with drawings, standards or models, we can also cover a very broad range thanks to our production capabilities and our diverse fleet of machinery.

This allows us to manufacture virtually any mechanical part that might be required, guaranteeing a consistently high level of quality for your precision parts – from a single source and at competitive prices – while simplifying the process of sourcing and managing suppliers and saving you money.

The next few pages give you an idea of our manufacturing capabilities. We would be delighted to have the opportunity to demonstrate our expertise in person.

Our turning systems are powerful and precise.

Turning

Our lathes allow us to cover a broad range of dimensions, meaning that we can turn pieces up to 6,000 mm in length and up to 700 mm in diameter.
Thanks to our capacity, we can maintain our high level of performance even when handling larger quantities and high machining volumes. Combining milling and turning also enables us to meet high requirements in terms of shape and position tolerances:

Our milling systems are powerful and precise.

Milling

We can use either horizontal or vertical machining centres depending on requirements. We only use precise, high-performance machinery. Long shafts are held in the dividing head and milled and drilled around their circumference in exactly the position required. Exchangeable plates on our horizontal centres allow us to set up our systems without impacting uptime, making our manufacturing approach particularly cost-effective.

We harden and straighten efficiently and precisely

Hardening/Straightening

We can handle induction surface hardening up to a diameter of 500 mm and a length of 6,000 mm as well as the subsequent tempering in a furnace.
This enables us to offer short throughput times and a monitored high level of quality even when working with hardened components. Our straightening press allows us to correct any distortion caused by the hardening process without delay. Additional heat and surface treatments are carried out by other accredited specialists, with priority given to firms local to us.

By selecting suitable companies and undertaking continuous quality monitoring, we can offer good quality at competitive prices at all times.

Here is a selection of possible treatments:

Quenching and tempering and annealing
Case and salt bath hardening
Nitriding and ferritic nitrocarburizing
Galvanising and phosphating
Bronzing
Anodising and coating
Painting/varnishing/lacquering and coating

We provide high-performance and precise grinding.

Grinding/finishing

Our machining tasks often place a heavy demand on accuracy and surface finish, so many of our parts are ground. This provides a high level of reliability, particularly following heat treatment, and a consistently high level of quality.

Superfinishing also lets us produce unbeatable surface finishes.

We mainly apply centreless grinding to machine bushings and shorter shafts.

WE OFFER FURTHER ACTIVITIES

Other machining tasks

We also handle additional machining tasks and activities associated with turning, milling and grinding.

The demagnetisation of components is becoming increasingly important, particularly in the mining industry. We can provide detailed testing and measurement reports on request and coordinate acceptance tests by certification bodies (DB, DNV, LROS, GL, etc.)
