BLM Group USA has introduced the LT Jumbo series automatic laser tube cutting system for large-diameter, thick-walled tubes.
The system can be used to cut round, square, and rectangular tubes, as well as nontubular open structural sections in diameters from 3 to 20 in. and lengths up to 60 ft. The machine can process mild, high-strength, alloy, and stainless steels. There is no need for special fixtures, which simplifies both high-volume production and low-volume prototype work.
All loading, cutting, and unloading operations are controlled by CNC, and the system control software automatically selects the best cutting method. Because all machine operations are performed by programmed commands, no manual setups or fixtures are required. Once tubes are placed on the loader, they are moved one by one into the feeding line with its automated chuck system.
Tubes are positioned under the five-axis cutting head according to the program parameters. The interpolation of the cutting head in combination with the tube movement allows for processing anywhere along the tube length. The machine can cut in front or behind the main chuck, or between the working chucks.
