Laser cutting heads for robot cutting (3D)

Laser cutting on complex workpiece geometries is optionally carried out on 5-axis systems or robots. Thanks to their particularly simple beam guidance, fiber-guided lasers are generally used, especially in agile robot applications. The insufficient path accuracy of robots as well as part and positioning tolerances often require additional axis systems directly on the laser cutting head. While a z-axis controls the distance to the workpiece, small cutting contours are traced with high precision by additional xy axes. The laser cutting systems are often part of complex production lines under difficult environmental conditions. The operators place high demands on the interference resistance and the ease of maintenance of the laser cutting heads.

Wide applications receive 3D laser cutting systems, especially in the automotive industry. Today robot-guided laser cutting is the flexible and highly productive method for machining high-strength body parts and profiles - for example, for inserting openings for the roof rails and antenna. From rigid stamping to flexible laser cutting - welcome to modern industrial production.

Precitec offers perfectly adapted solutions for 3D laser cutting. The compact and weight-optimized design resulted in high dynamics and great freedom of movement. Depending on the application, internal or external axis systems as well as various communication interfaces are available. Stability, ease of use and maintenance follow the typical high Precitec standards.

Laser cutting of auto body components and profiles

Automotive manufacturers use hot-worked heavy duty steels in auto body production that are difficult to machine with conventional methods. Cut outs on IHU components are often only assembled later due to the process. Today, robot guided laser cutting is the flexible and high-production method for machining high-strength auto body components and profiles. The robot-guided, highly dynamic laser head makes openings and trims e.g. B-pillars at up to 20 m/min. without tool wear.  

Greatest possible flexibility with highest precision

In case of insufficient robot track accuracy, the FormCutter is the right solution. The system includes a cutting head with an additional x-/y-axis-system. This makes the path programming easier and increases the cuttings precision. Especially in the automotive industries where multiple different types of holes e.g. antenna holes are cut out very late in the manufacturing process the system allows a technology exchange such as from rigid punching to flexible laser cutting.
