Dot-peening or Lasermarking?

 Nill + Ritz is also at home in the powertrain. Gearbox marking is also part of the core competence, regardless of whether it is manual, automatic, dual-clutch or electric transmission.

The request of one of our customers raised the question of whether marking should be carried out by scribing or laser marking in the current process. Since we at Nill + Ritz mastered both labeling procedures, we were able to contrast our motto "You have the application - We offer the right advice" without reservation Pro + Contra for both labeling procedures. The workpieces to be inscribed are gearbox components from the gearwheel to the ring gear and pinion shaft via gear shaft all the way to the complete gearbox housing. The tag contains a single-line text and a data matrix code. After a series of feasibility studies, much of the decision on the labeling laser. One of the reasons that spoke for the laser was the significantly faster labeling time and the greatest possible flexibility in adapting the lettering to the almost non-existent labeling surfaces on the gearwheel. In order to identify them, a workpiece position recognition was additionally installed. The camera can detect exactly the available labeling area (tooth) on which the DataMatrixCode is applied. The fine parameterability of the laser via our self-developed labeling software WinCamPro also ensures compliance with the very high requirement of residual dirt on the component.


The laser marking is not only faster, but also offers other advantages such as individual text design without tool change and lower downtime of the system, since the change of worn stamping tools is eliminated.
