The ROBA Orbital is designed for customers who, on the one hand, want to provide perfect foil or lacquered surfaces for flat workpieces with a high-quality sanding, or who produce furniture fronts in shaker design with a deeper filling made of MDF or solid wood.
If these fronts are made of MDF and the filling is created by clearing the center panel by using a CNC router, many milling lines are created. These overlaps of the tool paths must always be completely eliminated, otherwise they will holograph through a PVC film or paint layer.
Wood based cabinet doors have a different challenge: veneered fillings, raw or lacquered, must always be sanded smooth to ensure a top surface. In the case of framed doors, the sanding marks on the cross rials created by the widebelt sander must be removed.
The ROBA Orbital is equipped with two sanding units, whereby the unit with the rectangular sanding pad is intended for the filling area and the unit with the round sanding pad for the frame rails or surfaces.
Three tables ensure a high capacity because they work independently of each other: one table is loaded, one table is processed, one table is emptied. This creates a constant, high-performance workflow in a safe and dust-free environment.
The workpiece and frame width measurement is carried out separately and automatically for each table, while the cabinet door is moved into the machining area.
Long parts, such as interior doors, are placed transversely on the three processing tables, which are electronically coupled in the Y direction, and processed simultaneously by the three orbital units.
Fresh sanding discs are provided automatically by a programmed sequence from the tool changer at the back of the worktable. This results in a constant sanding quality with high output.
