Quality is a corporate culture

When it comes to production quality, UND is committed. Within our company, we have deployed rigorous quality control processes to meet the level of finish expected by our customers in the luxury, medical and aerospace markets.

Systematic quality control

Quality is the common thread running through all the industrial sectors for which UND works. This requirement has led us to develop internal control procedures to check the conformity of parts for each series. These control procedures can be reinforced at the request of a customer.
In our operations, it is necessary to comply with the relevant rules, which vary from one industrial sector to another. For example, in the aerospace industry, a part that has not been manufactured for two years will undergo a F.A.I. (First Article Inspection) to check and verify it before it goes into production.

Specific control equipment

Quality control is a daily requirement at UND and is applied to all our production processes, for example in the medical and aerospace sectors.
Our quality department is equipped with special machines, such as profile projectors and the ZEISS and VISION HAWK non-contact machine, to carry out automatic checks.Using these technologies, we can measure the dimensions of the parts produced in real time to check their conformity with an accuracy of 0.01 mm.

Cylindrical grinding of workpieces

Grinding is a production stage that we have mastered. This specific machining technique enables us to correct the surface of a part and improve its quality with micrometric precision (a tolerance of less than 0.005 mm), until we reach the reference dimensions expected by the customer.

0,3 mm, notre plus petit diamètre

At UND we use air-conditioned centreless grinding machines that guarantee tight tolerances on diameters (from 0.3 to 12 mm) and an exceptional surface finish.
In some cases, we grind the entire length of the part in a row.

Dive grinding

Plunge grinding is another facet of our expertise. This machining method is used to obtain high-precision internal and external cylindrical surfaces. Plunge grinding involves lowering the grinding wheel vertically.
We use this process for parts with special features. Dimensional precision and the ability to work on internal surfaces enable us to meet the needs of industries that demand high quality standards.

We rectify your material bars

Do you have bars of material that need to be ground for future machining? Contact us. We can grind bars of any material, up to 3 metres long, with a diameter of between 0.3 and 12 mm. One of our specialities in this field is the grinding of potentiometer axes and other axes.

Surface treatments

In addition to bar turning, polishing and grinding, UND offers a range of treatments for your parts. Surface treatment (anodising, silver plating, nickel plating, etc.), heat treatment (quenching, hyperquenching, cryogenics, etc.) and specific treatments are all possible finishes.

Lorem

These operations are not carried out directly by UND, but by local partner companies with whom we share the same culture of quality. This subcontracting is transparent for the customer. We take care of all the follow-up of the parts right up to delivery. At UND, we are the prime contractor for your parts. This global approach means we can deliver perfectly finished parts that meet your specifications, with every guarantee of safety, reliability and quality.
