While processing, the CoolLine nozzle directs a water mist around the laser beam as it reaches the work piece. In doing so, CoolLine reduces the heat transferred in the immediate cutting zone and achieves contours that would otherwise be difficult or impossible to process. With this new option the user is able to cut small sidewalls and difficult geometries more efficiently, especially in thick material. It also achieves a considerable increase in process reliability when laser processing low-grade material or material of varying composition.

In addition to greater flexibility in laser processing contours, there is a significant cost-advantage when cutting nests in thick material. Since the CoolLine option prevents the material from overheating, it allows parts to be nested more closely than was previously possible. By removing the heat and reducing the gap, fabricators process more parts and reduce scrap. Smaller webs significantly reduce the amount of raw material between parts, allow fabricators to more fully utilize the sheet and thereby achieve greater profits.
