Foundry
With its own up-market aluminum foundry unit, SADEV is able to achieve its own casings. The process used matches our team, to provide thin pieces with complex shapes while respecting the necessary precision for motor sport activity.

The High-strength alloys are dimensionally and structurally controlled by radiographic and dye and fluorescent penetrating inspection.

Drastic traceability ensures quality of our products.

The molded housings for transmissions are machined on palletized machining centres in SADEV facilities.
Turning-Milling
Our industrial park consisted of several CNC lathes and CNC machining centres, is operated by skilled operators in achieving complex parts. The integration and optimization of machining programs are handled through a methods department and downloaded directly on the machine platform.
The modernity of our turning - milling cell, CNC lathes with up to 8 axes, and palletized machining centres, allows a wide range of machining possible. Advances in technology and cutting combined with the SADEV experience offer high-precision machining.



Drilling
For parts requiring a hole from Ø4 to Ø32 mm lg 1000 mm, SADEV has a drilling unit dedicated to this operation.
Spark machining
The spark machining skill offers the possibility of profiles difficult to achieve with standard tools, and with high precision


Gear cutting
SADEV is equipped with a wide range of machine dedicated for internal and external cutting. We can make specific teeth profiles and grooves as requested. Many kind of standard splines can be broached by hob cutting. The experience and diversity of cutting by SADEV have enriched a range of tools and provide an important control of gear cutting.

This area of competence reached a level of technology thanks to the bevel gear cutting machined on KLINGENBERG CNC, and straight gear cutting on LIEBHERR CNC. The control is done in parallel on a bench P26, and automatically download the correct values on on the machine, which ensures a consistent quality on small and large series.
Heat traitment
SADEV has dedicated a full installation to heat treatment, fully computerized, it provides a 24/24h operation. The processing unit is consisted of a furnace for cementation, air and oil quenching, a cryogenic chamber and a tempering oven.


To ensure the required metallurgical properties, processes and results of treatment are validated by a laboratory, equipped with a microscope, micrometer and binocular microscope.


Grinding

The activity of SADEV requires greater precision with extremely small tolerances. To meet this requirement, SADEV operates an area with a number of machines for the multiple grinding operations, drive by resurfacing or millstone.

Our units KLINGENBERG CNC and LIEBHERR CNC, in addition to their function cutting, perform the function teeth grinding. The control teeth is carried out on a bench P26 which, like trimming, computer applies corrections.
Surface treatment
In an ongoing effort to provide quality, SADEV has developed processes to strengthen surface, such as shot peening, and then to propose a flawless surface, SADEV has a super finishing machine park.

Electron beam welding
In its desire to be at the cutting edge of technology, SADEV has recently acquired its own welding beam of electrons. This skill has the potential to achieve high quality welds and precision on a wide range of grade and materials. Its various lines of movement can also produce many possible shapes of welding.
