Robellaz & Cie SA

.

	Established in 1902 in Ste-Croix, a small town in the Jura mountains hotbed of the Swiss watch industry

This family owned and managed company has a long history of supplying rubies to some of the most prestigious watch manufacturers. It has acquired through the years the necessary know how to machine with extreme precision very small parts and produce micro-miniature components as well as assemblies in a variety of ultra hard materials such as rubies, sapphires, tungsten carbide, ceramics, and more.

Smaller and smaller holes is our motto.
A 5 microns hole through a 0.5mm (.002”) outside diameter ruby, is no longer an objective it is our daily reality.

Our ultra hard components are used in a wide variety of applications, sometimes quite unusual:

• A ruby with a 10 microns orifice will be mounted on the oxygen generating system of the spacecraft taking the first men to Mars.

• Oil is calibrated trough a sapphire orifice mounted in high precision valves used to control flaps on many airplanes and in Formula One hydraulic gear boxes.

• Baby dippers are cut with water jets, a technology using miniature holes through sapphire mounted nozzles to created ultra high water pressure

It is fair to say that a wide array of industrial sectors can benefit from the use of such components, providing unrivalled wear, heat and corrosion resistance.

We can also mount our machined parts in numerous materials such as stainless steel; copper, bronze, aluminum, and others. Close product design cooperation with our clients, allows us to offer the best results in terms of quality, performance and price.
