Superior wear resistance, of course, means a reduction in the number of nozzles purchased over time. But longer life also means nozzles maintain an optimum jet pattern and velocity longer. This allows faster average cutting speeds and significantly reduced system downtime for nozzle re-placement and system calibration. It also means greater dimensional accuracy and the ability to perform longer, uninterrupted cuts. These performance enhancements combine to make the entire cutting process more cost-effective. The long life focusing nozzles (also referred to as mixing tubes) are for use on Flow™ and other water jet cutting machines.
