Robotic composite sanding
Sanding is one of the most commonly applied processes in all sectors of the industry.
It improves the surface finish of a part by eliminating geometrical defects and change its roughness value. The result is:
This process is still mainly done by hand as the quality of the sanding depends on the operator’s skill and dexterity. It is, though, a particularly arduous task, that exposes operators to dust that frequently generates MSD (Musculoskeletal Disorders).
GEBE2 has developed a robotic sanding solution that reproduces the operator’s gestures and sensitivity. The central element, the effector, is equipped with a random orbital electric sander and a compliant device that applies a constant force in all directions, to the nearest N.
To enhance the autonomy and performance of their cells, GEBE2 has equipped its robots with automatic disc changers that provide for using a range of grain sizes.
Sanding quality is strongly related to the regularity of the sander’s motion on the part. Our offline programming software simulates all possible trajectories with a graphic display of the material’s removal.
GEBE2 provides custom-engineered CAD/CAM software for robotic sanding that programs trajectories in hidden time based on the CAD file of the part. The graphic display of material removal guides the programmer and helps him obtain a smooth surface.
This multi-head robot is perfectly designed to work on large parts. The robot-assisted effector maintains a constant force on each disc, along with remote shape tracking, while remaining perpendicular to the surface. Thanks to this patented technology, it is now possible to sand thin, flexible parts using lightweight, cost-effective tools.
To manufacturers facing small series and great diversity of parts, this is the appropriate and affordable solution. The autonomy of this COBOT improves the productivity of manual operations. Thanks to its mobility, it can be easily adapted to existing workstations without modifying the location of the workshop.
Without any special training, the operator becomes a COBOT Pilot, while retaining his profession. Finally this innovative collaborative sanding equipment meets the challenges of MSD (musculoskeletal disorders) increasingly present in production workshops.
Feasibility study of interior and exterior sanding of bodyworks with complex geometry in order to prepare parts for coating. The programming is fully simulated on the cabin’s digital file using CAD/CAM software.
A sanding robot’s autonomy depends on its disc changer. This device removes used abrasives and distributes new discs. Several disc storage can be installed depending on the range of grain sizes used.
