Han-Kwang USA has announced the immediate availability of the model PL 3015, a long-bed, 2-D, flying-optic laser system that handles workpieces 60 in. wide by 120 in. long. The long-bed gantry arrangement requires less motion on the machine, which helps provide greater working stability and reduced maintenance requirements, the company says.
The machine features single-axis speed of 4,724 IPM, simultaneous XY axis speed of 7,900 IPM, and maximum cutting speed of 1,181 IPM, all with positioning accuracies better than ±0.004 in. per 118 in. of travel and repeatability to 0.001 in. A dual shuttle pallet system is onboard.
The laser system has a Panasonic CO2 laser resonator in 2-, 2.5-, 4-, and 6-kW versions, as well as the builder's patented beam radius control, which optimizes the beam diameter for various material substrates and thickness variations. Additionally, the constant beam delivery system provides consistency in the beam quality at the focal point.
A plasma monitoring unit constantly tracks cut errors to help reduce out-of-tolerance conditions in the cutting cycle, while a built-in lens crack sensor monitors the state of lens contamination. Instant alerts through the onboard Siemens CNC provide operators and maintenance personnel with immediate alarm notifications.
An optional rotary axis is available for tube cutting up to 12 in. OD. Fully automated materials handling systems and pallet towers also are offered by the company.
