The Trumatic L 2510 machine from Trumpf Inc. is said to combine an integral load and unload device with a high-speed, laser-cutting machine that results in a compact and productive flexible manufacturing cell.
According to the Farmington, Connecticut, U.S.-based supplier, the machine utilizes a rapid in-line load and unload device for all material handling tasks, eliminating the need for a traditional pallet changer. The result is said to be a more productive, fully automated machine, with a footprint similar to a simple pallet changer machine. The flying optic design reportedly achieves high processing speeds and consistent accuracy independent of material weight. Optimal cut consistency is reportedly achieved by integral mounting of the laser resonator on the machine frame.
Trumpf says at the beginning of the production run, the suction frame picks up a fresh sheet of material from the loading station and moves into the work area where it deposits the sheet on the stationary cutting table. The suction frame then exits the work enclosure and prepares the next sheet for loading. The laser processes the nest of parts as programmed. When cutting is complete, the unload device is driven into the work area where the entire nest of cut parts is lifted off the cutting table with unloading forks. Simultaneously, the next sheet of material is loaded.
The load and unload devices are mounted directly to the machine frame and are tailored to match the cutting capabilities of the TCF 1 laser, a CO2 resonator. Diffusion-cooled technology eliminates the need to circulate the lasing gas in order to cool it, resulting in fewer moving parts and a smaller enclosure. Trumpf says the annular discharge and small laser cavity offers excellent beam quality and low gas consumption, which also lead to faster processing speeds. The low gas consumption allows the small internal gas bottle to last a minimum of 1 year.
The laser cutting system offers simplified integration on production floors, when compared to a traditional laser-cutting machine. Other features include reduced floor space and gas delivery requirements, no external laser gases required, no special foundation necessary, and load and unload possible from three sides. With material changeover times of less than 1 minute, Trumpf says the laser cutting system offers maximum efficiency during manned operation and allows unmanned production.
