Two, new-generation fibre lasers that offer solutions for both integrators and users, have just been introduced by TRUMPF. The TruFiber S and TruFiber P series are versatile tools for welding and cutting thick, thin and particularly challenging materials and even additive manufacturing. They are robust, reliable and provide long-term, high process stability. With up to six kilowatts of power output and a sophisticated array of optics, sensors and software, they can be easily integrated to meet a wide range of manufacturing needs.
A multipurpose tool
The TruFiber S pairs a powerful beam source with advanced features such as BrightLine Weld, a technology that boosts process quality and productivity and can distribute the full laser power between the core and the surrounding ring into a two-in-one laser light cable. The beam delivery system has one or two outputs, with the latter delivering laser light to two systems. Connecting and disconnecting laser light cables is an exercise in convenience, making the TruFiber S an excellent choice for large production lines, such as those in the automotive industry.
The TruFiber P offers an output with a spliced laser light cable and the VariMode option, which allows the laser’s beam characteristics to be adapted to suit varying manufacturing requirements. The newcomer can therefore be used to process thin steel and aluminium at high speeds as well as copper, brass and other reflective materials. It takes less than 40 milliseconds for VariMode to change the beam profile to achieve the best surface quality for the application. The feature also allows users to increase production speed and reduce costs while enhancing process quality.
An important feature of this fibre laser is TruControl that provides convenient laser start-up, definition and storage of up to 1000 different laser programs. This flexibility is enhanced by the inclusion of all relevant interface buses. TruFiber P is expected to be to particularly beneficial to the e-mobility, automotive or medical technology sectors.
Both of the new TruFiber series feature Active Power Control to keep output power constant and eliminate the effect of diode aging. At microsecond intervals, a power sensor compares the value pre-set on the laser with the actual reading and automatically adjusts the output in the event of a discrepancy. Robust processing optics and programmable focusing optics (PFO) facilitate remote welding and drilling.
VisionLine image processing ensures accuracy during welding by automatically pinpointing the target position for the weld on the components. And another feature, CalibrationLine Focus, checks and corrects the focus position of the part. CalibrationLine Power does the same for the laser power level; this check-and-correction routine takes place at user-definable intervals.
Smart process surveillance
Smart View Services is a real-time surveillance tool with clearly arranged dashboards and straightforward displays for customers to monitor key data, wherever they are in the world. It also sends this data to TRUMPF for its experts to check and verify the validity of key parameters and draw on machine learning to determine if maintenance is needed. This remote monitoring is designed to help boost machine availability and efficiency.
