PRESENTATION
It was in 1974 that Daniel Cagnon opened his precision mechanical engineering workshop at Carouge, in the suburbs of Geneva. He quickly became a sub-contractor for most of the major metallurgical companies in Geneva; firms which, for the most part, are no longer around.
In order to survive and develop, the DC-Cagnon workshop had to diversify and, in response to demand, deliver its clients increasingly complicated parts involving greater levels of precision, ready for fitting in machines and apparatuses. The company also took on niche business not found locally, such as repairs, conversion work, or the creation of mechanical or electromechanical assemblies. In order to pursue this programme, Daniel Cagnon took the opportunity to buy up machinery from several workshops that were in decline, including a surface treatment workshop. Furthermore, he modernised his range of machines with several machine centres, some of which are highly advanced, enabling him to deliver extremely complicated very high-precision parts to his clients.
In 2003, the firm underwent major restructuring and regrouped its business operations at two sites with a total surface area of 1,200 m2: the Clos de la Fonderie site, which is where the Mechanical Engineering and Products departments are located; and the Rue Baylon site, where the DC-Finishing surface treatments department is located. The company’s share capital was increased, and a new company name was adopted: Ateliers Cagnon SA .
Corporate structure
The TM Workshop (Turning/Machining) brings together conventional machines which, more often than not, are CNC digitally controlled machinery, for turning, milling, drilling, tapping and planing. Many years of experience enable this work to be carried out on practically any metal, from aluminium through to stainless steel and titanium, as well as on certain plastics suitable for these operations. The TM Workshop also carries out rectification work such as honing or grinding internal or external diameters.
The SB Workshop (Sheet Metal Working/Boilermaking) enables all sorts of sheet metal items of all thicknesses to be made from metals such as aluminium, copper, brass, or fine stainless steel sheeting. A series of machines are used to cut these items, fold them, and perform complex cutting operations (using the Raskin machine). If necessary, this sheet metal can be assembled using various welding processes, such as oxyacetylene welding, plasma welding, mechanical welding, or TIG and MIG welding for aluminium or steel alloys.
The S5 Workshop (Specialities and Services) executes the most complex mechanical parts with the utmost precision. To achieve this, the workshop has several machine centres, as well as a Ferrari machine for 5-axis high-speed milling.
This department’s flagship product is the manufacture of moulds for blowing the PET bottles used for soft drinks. Working from a rough block of aluminium alloy, Ateliers Cagnon SA carry out all the operations required to make these moulds ready for mounting on bottle-making machines. This process starts with traditional machining work, followed by high-speed milling for the complex inside shape. The moulds are then subjected to mirror polishing by hand. Lastly, these pieces undergo an external colouring and anodization surface treatment, and the manufacturing brand and the tool’s characteristics are engraved on them with a laser.
It is also in this workshop that cutting tools are made and sharpened, both for in-house needs and for third parties. Assembly, conversion and repair work on mechanical or electromechanical assemblies is also carried out in this department.
The SQ Service (Studies and Quality Control) is capable of completing manufacturing designs on PC, based on a simple drawing supplied by the client. But this service’s main role is checking manufactured parts. To achieve this, in additional to traditional instruments such as comparators, various types of gauges etc. the inspectors have a TESA calibration machine for performing 3D electronic checks using a robotized gauging probe.
Quality Assurance: At the request of one of our clients, working in accordance with the ISO 9000 Quality Assurance standard, we can supply a “Certificate of Conformity” along with the manufactured parts, certifying that they have been checked in accordance with the order specifications.
The PP Workshop (Prototypes and Pre-Production) and the FP Workshop (Finished Products) are devoted to delivering finished products to clients that are ready for sale. For example there is the Vulcain tabletop barbecue unit, which is mainly intended for restaurants. And special mention should be made of a product that was entirely developed, manufactured and tested on a test bench by Ateliers Cagnon SA, which is the:
DC 80 TURBO-JET, a jet engine that runs on kerosene, intended for use by model aircraft enthusiasts. This engine, which weighs 1.2 kg, has a turbine that rotates at a speed of 117,000 rpm, producing static thrust of 8.2 kg. It can be fitted to a scale model aircraft with a wing span of 1.8 metres and, operated via remote control, enables the aircraft to handle manoeuvres worthy of an FA-18 fighter aircraft, at speeds of over 300 kmph.
DC - Finishing is the surface treatments workshop located at the Rue Baylon site, which is also at Carouge in Geneva. The following various treatments are offered:
Mechanical treatments, carried out on metals such as steel and aluminium alloys. These treatments include grinding, brushing, brilliant polishing, mirror polishing, sand-blasting, shot-blasting and shot-peening. This is mainly manual work.
Galvanic and chemical treatments, enabling a thin layer of metal that is different from the base metal to be deposited on the surface. These treatments involve work such as tinning, galvanizing, coppering, nickel plating, chromium plating, hard chromium plating, silver plating and gold plating.
Aluminium anodizing, enabling the surface to be protected from natural oxidation and the creation of a transparent surface layer which may be coloured or have decorative graphical printing on it. We should also mention hard anodizing for wear resistance, and the Ematal process, which provides a very good friction coefficient. The Alodine 1200 S process, which is purely chemical, also protects aluminium from natural oxidation. It is primarily used as a bonding layer for paint.
DC-Finishing is also equipped for spray gun paint work and thermo-lacquering of parts with all sorts of shapes and made of any sort of material.
The LE Workship does Laser Engravings of texts and artwork of various sorts on all solid, metal or other supports.
To conclude, from this description you can see that the new workshops at Ateliers Cagnon SA are able to meet the widest range of demands, from the simple manufacturing of a mechanical part according to a drawing, through to the manufacturing of prototypes or pre-production models of apparatuses of the utmost complexity.
