Tube cutting system with broad chucking range engineered for heavy tubes

August 11, 2009

TRUMPF's TruLaser Tube 7000 laser cutting system processes tubes inside a tunnel-like safety enclosure and then moves them forward to the brush table or ejects them to a parts container behind the machine. Its heavy-duty drives are engineered for heavy tubes, and it features a broad chucking range.

The machine can cut tubes and profiles with large diameters and wall thicknesses. It processes tubes up to 30 ft. long and can handle a maximum weight of 496 lbs. The system features a 0.6- to 10-in. clamping range and is available with up to 3.6 kW of laser power.

When changing programs, nearly all of the adjustments depend on profile specifics. Values that have to be entered at the machine and the loading unit can be handled by the parts program. The self-centering chucking jaws do not need to be changed, and the rollers that provide support and lateral guidance for the tubing automatically adjust to the diameter. Even the integrated scrap container in the feed station is emptied without operator intervention.

he FocusLine function automatically adapts the laser focal position to the material type and thickness. The machine's software independently adjusts to the focus parameters given in the technology table. Also new is the slender cutting head with a 6-in. lens and new clutch style.

When combined with the LoadMaster Tube, featuring a tube magazine that can hold up to 8,000 lbs. of raw material, the system can be fully automated. Its pivoting feed support holds a number of tubes and keeps them at constant orientation. Special profiles and small batches can be fed by a conveyor section.
