Things used to be better in bygone times? Indeed, not really. Watchmaking has consistently depended on innovation and it has developed along with the apparatus, instruments and methods that make watch creation conceivable, just to keep on top of the occasions. Therefore, we’re bringing you “in the background” at Vaucher Manufacture Fleurier to perceive how watch parts are made.
The careful handwork that goes into the assembling of Haute Horlogerie watches is captivating. Yet, when visiting watch creation offices, the “unoriginal picture” of the old, free watchmaker at his seat is dissipated. There, close to experts, you’ll likewise find best in class CNC machines, lasers and forefront gear. The business has gone through huge industrialisation significantly improving the nature of the parts manufactured… Technology is a basic power in the turn of events and development of watchmaking art.
Today, we take you in the background of the watch business at Vaucher Manufacture Fleurier (VMF) to view four distinct strategies for creating watch parts, clarifying why and how they are ordinarily used.
Editor’s note: the creation strategies we are introducing here are those for the most part utilized at Vaucher and these are normally not by any means the only ones – think bar turning, Liga, infusion, DRIE…
A customary creation method, stepping comprises of cutting and collapsing parts from metal sheets. Plans are moved into stepping instruments that are mounted into presses. In reformist pass on stepping, a metal strip is shaped into a completed part in a few operations.
Stamping devices are complex and costly to manufacture, yet they permit the creation of exceptionally precise components with repeatability and a high efficiency. The creation resistances are of +/ – 2 microns.
The choice to create a section in stepping relies upon its size, complexity and on the volume of creation. When all is said in done, it is utilized for huge creations of components in steel, metal, CuBe or gold. This is generally utilized on moderately slight parts.
Machining is a cycle where an instrument (processing and penetrating) eliminates material from a piece of crude metal to get the ideal shape. It is utilized for the sequential creation of plates and scaffolds, to make their complex shapes with accuracy. These are created from metal plates (named barquettes for those anxious to fabricate their French watchmaking jargon). Some are machined dry or with oil to grease up and keep the piece at a stable temperature.
Several arrangements are utilized at VMF to be adaptable and adjust to clients’ needs, specifically for Haute Horlogerie short-arrangement creation. Fleury Modulo is a robotized dry assembling arrangement with a secluded direct exchange. Everything modules can work exclusively or be grouped. At Vaucher, two assembled lines are utilized, one for extensions and one for plates. Two ungrouped Modulos are additionally operated.
Primacon machining focuses are utilized to manufacture parts in explicit metal composites or titanium. Titanium is light, solid and safe however these properties are a revile for machining requiring the utilization of coolant.
Cutting-edge Willemin-Macodel focuses have recently been procured; these are explicitly adjusted for machining watchmaking components. Among their specificities, these element a modified delta robot – where the component is moving and not the apparatus. The machine’s equal construction empowers the load moving to be limited. Process durations are fundamentally diminished while accomplishing outstanding submicron precision.
Last, Vaucher likewise combines machining metal strips that have been stepped, exploiting both the accuracy of stepping and the adaptability of machining. A fundamental piece of the skill lies in the ability to expand creation measures… In the video underneath, instances of machining at Vaucher: 1.Dry machining – 2.Machining with coolant – 3.

Wire disintegration is an electro-warm cutting cycle. A slender metallic wire fills in as a terminal to dissolve and cut a shape in a workpiece.
Wire disintegration is appropriate for mind boggling or thick parts (for example apparatuses) and short runs. It very well may be utilized for restoring in any case rejected parts. VMF utilizes wire disintegration generally to manufacture stepping bites the dust and openwork parts.
Laser Machining, Marking And Engraving
Over the previous years, VMF has built up a mastery in laser etching, stamping and machining. These subtractive assembling measures utilize nuclear power to eliminate material from metal, pointing a laser towards the workpiece.
Laser machining permits fabricating profoundly precise parts. It is fit to machine flimsy components (up to 0.8mm at VMF), especially for limited scope creation, for which the creation of stepping apparatuses would be excessively long and excessively costly. VMF works generally with Durnico (a steel assortment used to create springs), metal, CuBe and titanium.
Among the one of a kind ability collected by VMF is laser cutting on both barquettes and metal strips.
