MB Roba Bottom Sander is designed to be used as a white wood, MDF, and intermediate lacquer sander. Specifically designed to reduce the need to run pieces through a sanding line multiple times. Sanding on the bottom is achieved by using a vacuum from the top to smoothly move the parts through. Some of the key features of the Roba Bottom Sander are the integrated touch screen controls, complete control of feed and sanding movements, and modular settings for different aggregates.
