To use positioning lasers in manufacturing is not exactly new. The laser projection is already being used during assembly instead of technical drawings in a watch manufactory. The laser projector is installed above the workstation and leads the fitter with visual support through the individual work steps and marks the next assembly part and the next location e.g. with a laser cross. Due to the special focus mechanism, the width of a laser line is just 0.3mm, thus precise laser projections in the form of article numbers, letters and any other form are possible. Whether watches or complete engines are manufactured, it is worth to use a laser projector for these high-quality objects even at small numbers. Later rework or expensive exchanges are avoided already in advance.
