Our redENERGY EP-Z Laser benefits from having longer duration pulses which can have significant benefits in engraving applications.
For this application WF 39 which is a 500ns pulse (full width) was used to achieve 0.2mm depth on this logo in a time of 195s using a multi pass engraving technique. A high quality finish was achieved through the use of periodic interpass cleaning with WF25 which has a shorter 20ns duration pulse. This less intense pulse removes debris and oxide from the surface which can accumulate and have a detrimental effect on engrave quality.
500ns pulse material removal rates of up to 5.25mm3/min can be achieved which compared with the traditional 200ns pulses (which give removal rates of 4.25mm3/min) offers a 25% increase in productivity.
