FARMINGTON, Conn., Nov. 2, 2012 — Trumpf Inc. has introduced CoolLine, a new option for its Trumpf 2-D laser cutting machines that uses a water mist to cool material as it is cut.
It is integrated into the cutting process via a specially designed laser cutting head, various nozzles and a water supply tank. Fabricators achieve higher-quality cuts with smaller contours and greater complexity and can nest parts closer together.
The nozzle directs a water mist around the laser beam as it reaches the workpiece, and the heat transferred in the immediate cutting zone is reduced. Contours that otherwise would be difficult or impossible to process can be achieved. The user can cut small sidewalls and difficult geometries more efficiently, especially in thick materials. Laser processing low-grade material or material of varying composition can be performed.
With the heat removed and the gap between parts reduced, fabricators process more parts and reduce scrap. Smaller webs significantly reduce the amount of raw material between parts, allowing fabricators to more fully utilize the sheet.
