Let our crew take you on a quest for excellence.

analysis of plans and specifications

The method department verifies the feasibility and proposes the best industrial solution in terms of quality, price and delivery time.

Raw Materials

The forged material, in rolled round or bar form, is sourced from approved and certified European suppliers.

tournage

As at each stage of the manufacturing process, the turning stations are doubled to respect the schedule in all circumstances. Each operator evaluates, completes and then transfers his precious know-how to the other members of the team.

Cutting

Carried out on high-performance machines, hobbing is carried out by hobbing, cutter or broaching for straight, helical or chevron, internal or external teeth, from module 0.3 to module 35 and diameters from 5 to 2600 mm.

Heat treatments

For more than 30 years, a close partnership with a network of recognised specialists has enabled us to meet the most stringent requirements :
stabilisation, case-hardening-tempering, nitriding. induction hardening...
On request, the mechanical characteristics are tested by an independent laboratory.

Special Processes

Every day, operators certified and qualified by our customers implement special processes:
Nital Attack.

Magnetic resonance imaging [COSAC, Level 2 AND 3].

Deoxidation.

Glueing.

Abral [Super serrated finish].

Micro-hardness.

Cylindrical grinding

The know-how of the dimensional grinders guarantees the perfect geometrical quality of the part before its teeth are ground. The operations of rectification are carried out in a fully air-conditioned room of 1.000 m2.

Gear grinding

Up to diameter 2600 mm, our high-tech gear grinding machines achieve a quality 4 on the gearing.

The different grinding techniques [master wheel, form wheel or plate wheel] are specific solutions to obtain the following results the required tooth profile.

Gear cutting

Module: 0.5 to 35
Diameter: 10 to 2500mm
Straight, helical, conical gearing, wheels and worms, chevrons, pulleys etc.

Broaching

Equipped with numerous skewers and mortising machines, we can make all types of keys and splines, individually or in series.

Gear grinding

From 10 to 2500mm, we can grind with our Reishauer, MAAG and Gleason machines any type of gearing and obtain a gearing quality of class 4.

Turning Milling

Aeronautics

EN9100 certified for many years, we have been supplying parts for major engine manufacturers in the civil and military sectors.

Ferrovière

Also certified ISO9001 2015, we supply engine manufacturers in the ferrous sector.

Maritime

Precision on large sizes does not scare us, we also produce for the maritime industry.

Industry

Gears, pinions, pulleys and toothed racks for industry
All complex and precision parts made to drawing with teeth can be studied and manufactured in our French factory.

Optimize your supply chain

Sourcing parts from precision plans can prove to be a real obstacle course :
At CMW you will find a quality partner: high precision gears and lead times.
