3-D Laser Processing Machines


TRUMPF is introducing a new line of 3-D laser processing machines, the TruLaser Cell Series 7000, to the North American market. The line of modular laser cells and the largest available 3-D laser machines offered by TRUMPF, the TruLaser Cell Series 7000 offers flexibility for many different areas of application. "From aluminum to ultra-high-strength steel, in 2-D or 3-D, the TruLaser Cell Series 7000 can weld, cut, and process surfaces economically,” explains Tim Morris, general manager of the TRUMPF Inc. Laser Technology Center in Plymouth, Michigan. The X-axis travel of the TruLaser Cell 7020 is 79 inches. The Y-axis is designed as a cantilever with a working range of 59 inches. It supports a very narrow, compact and fast Z-axis with a 30-inch working range. The X-axis travel of the TruLaser Cell 7040 is 158 inches. The Y-axis is designed as a cantilever with a working range of 59 inches. The Z-axis design is the same as the TruLaser Cell 7020. It supports a very narrow, compact and fast Z-axis with 30-inch working range. Two rotational axes give the TruLaser Cell machines 3-D flexibility. The machine creates dynamic performance through high travel speeds and axis accelerations up to 2.5G on the dynamic cutting head and 0.8G in the linear machine axis. The focus position and diameter remain constant over the whole working envelope of the machine, ensuring uniformly high processing quality regardless of laser power and component position in the working range. Engineers at TRUMPF have created a processing head with magnetic coupling as a special innovation. The magnetic coupling allows the operator to snap the head onto the machine easily and automatically detaches it should the head collide with the workpiece. The alignment of the head after it detaches is eliminated, this minimizes the downtime due to collisions or crashes. Automatic head identification eliminates operating errors when switching the processing head and allows for a fast exchange. The user-friendly hanging operating panel, which as an option is moveable along the front side of the machine, provides the operator with a good view of the process and eases the part setup. An additional ergonomic teaching panel with 6-D mouse and a portable screen allows the machine to be controlled and taught easily. The automation options are also important to the user, particularly for increasing productivity. For example, the dual-station mode enables simultaneous loading or tooling setup while components are processed. Linear and rotation changers are also available for simplified handling of components or a more ergonomical production flow, which also increases the productivity of the system. The modularity allows all automation components to be easily retooled (retrofitted). The dynamic performance of the TruLaser Cell Series 7000 is important for cutting stampings or other formed sheet metal parts. For example, the cell could cut the processing time by 50 percent in the production of a passenger car B-pillar made of hot formed ultra-high-strength steel. Compact laser processing cells with minimal space requirements are available with TRUMPF CO2 lasers with up to 6,000 watts of laser power for cutting applications and 15,000 watts for welding applications. TRUMPF solid-state lasers up to 8,000 watts can also be used.
