Recent developments now make it possible to have laser sources which combine performance with compactness – several hundred Watts in less than 20 cm high. These equipments produce a beam of such high quality that they are capable of welding spots just a few tens of microns in diameter.
The same laser can operate in either pulse or continuous mode, making it possible to cover an extremely broad range of applications and to work on a large spectrum of conventional and precious metals.

Example of micro part realized on a laser Cheval machine. Machining without bending produces a level of accuracy of a few hundredths of mm (or less) on parts varying in size from 0.05 mm to several mm thick. A wide variety of materials can be cut and pre-cut using laser technology : steel, precious metals, alumunium, magnetic sheeting, copper, brass, thin sheeting, ceramics, wood, plastics...
Industrial micro-assembly These characteristics enable Laser Cheval to offer compact, efficient micro-assembly machines operating either automatically or semi-automatically. They are equipped with camera optics, saving operators the fastidious task of working with binoculars and allowing them to view the blanks to be welded from several angles. These optical viewing systems can be automated and allow for precise repositioning of spot welds on blanks, guaranteeing the reproducibility of assembly operations.
Complex assemblies Thanks to the flexible functionality of this machine, it now serves a large number of companies in the fields of watchmaking, jewellery, the medical sector, aeronautics and electronics. All these industrial customers are working to develop assembly techniques to enable them to produce complex assemblies by welding simple components while keeping production costs low.
Last but not least: micro-cutting In addition to their potential for welding, these laser sources can also be used for micro-cutting operations on virtually all metals. Laser Cheval also has a testing department and a subcontracting department, which enables it to offer its customers a wall-to-wall service from development of the prototype laser process, production of the pre-series for validation and sub-contractor series during the study, right through to the final production of their machine.
