Sanding robot for metal parts

Our sister company 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.

Programming sanding operations

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.

Examples of sanding robot applications for metal parts

Robotic sanding of large parts

Robotic sanding cell realized for SABCA. The robot is mounted on a rail allowing to work on large parts (up to 8m length). It is equipped with a laser recognizing the parts and adjust its position.
The robot uses 2 end-effectors to work: a sander with an automated disc change system and an electro-spindle working with different deburring or sanding tools.

Sanding robot for metal parts - cosmetic application - GEBE2 | EMPOWERING TECHNOLOGIES

COSMETIC FINISH ON ALUMINUM ALLOY

This metal sanding application is designed to hide machining traces and obtain a uniform appearance over the whole surface of this out-of-round piece. This is achieved using a sensitive sanding effector that apply a constant force along the tool path. The sanding machine is still normal to the surface, that optimize the effectiveness of the process and the quality of the part.

POLISHING MACHINING GROOVES ON TITANIUM

In order to improve the surface appearance of shaped parts post-machining, the robot moves along the workpiece applying a rotary tool fitted with an abrasive material with a controlled force. Great care has been taken to create trajectories in order to obtain uniform roughness. This polishing operation can be combined with a random orbital sanding operation for finishing.

ALUMINUM PANEL STRIPPING

Stripping removes all machining traces that could reduce part fatigue strength including, in particular, aircraft wing panels. This application uses rotary tools associated with a compliance that guarantees uniform treatment.

AUTOMATIC DISC CHANGEOVER

The disc changer is vital to ensuring autonomous operation of the sanding robot. This patented device removes used abrasives and distributes new ones. Several disc feed storage can be installed depending on the range of grain sizes used.
