In several development steps with cutting trials, Precitec has increased the flow rate through the cutting nozzle while keeping the cutting gas pressure constant. The KT B CON ceramic part and the nozzles now have no 'hard edges' and have a conical geometry. Thus, the cutting gas pressure can be reduced while giving the same cutting edge quality and the input pressure directly on the processing head can be reduced.The company said that field tests with the new design have also shown an increased working range for the focal position. Dirt on the focussing lens and the associated focus shift can be detected with the larger process window and increase the operating life of the optics. With CO2 cutting heads without a protective window in particular, this leads to cost advantages.
