Laser Marking in Mechanical Engineering
Durable and Resistant to Wear and Tear
Annealing is used with all metals which show a color change when exposed to heat and oxygen. The laser marker selectively heats up small spots of the workpiece surface until annealing colors appear. Annealing leaves the material surface unharmed but still produces high-contrast, clearly legible laser markings.
The laser engraves the material surface down to some 10 µm in depth. Engraved marks are exceptionally durable and can only be removed by heavy grinding. Therefore laser engraving is used for forgery-proof product marking e.g. of ball-bearings. Both marking methods offer almost unlimited possibilities in terms of marking contents and shape and are suitable for small and large batch sizes.
Laser Marking of Cutting Blades
- Mechanical engineering often makes use of highly resistant components whose manufacturing process has to be completely traceable due to quality assurance requirements. Wherever commonplace marking methods are inflexible, slow or prone to wear, laser annealing or engraving is the solution.
