The ROBA Twin Flat machine stands out due to the simple operation and optimal denibbing results. Processing time is shortened considerably. The machine sanding aggregate is divided into two areas: The flat part of the work piece is sanded in an area with a short sanding paper setting. This area is 150 mm wide. The shaped profile part is sanded in a second area, set-up with narrow slotted paper, to be able to get easily into the depths of the profiling. This area is 100 mm wide.
