Both machine stands are designed with a recess, allowing longer parts to be ground on the machine. The three-roller belt guidance system provides the operator with a maximally open working area, making it especially suitable for use with hand sanding blocks. The belt drive is powered by a three-phase motor with a dynamically balanced drive roller. Each sanding belt features individually adjustable pneumatic tensioning for optimal tensioning force per belt. The dust collection system is dimensioned to efficiently capture grinding dust and direct it towards the extraction nozzle, when connected to a proper extraction unit. For fatigue-free operation, the sanding unit is mounted in play-free roller guides. The machine table can be easily and quickly adjusted to the required workpiece height via motorized elevation, with maintenance-free elevation guides. For loading, the table can extend far enough so that workpieces do not need to be pushed under the sanding belt. All main function controls are ergonomically positioned at the center of the machine. Ledjv S Sr Rspfx Afgjhf Machine color: RAL 9001 cream white and RAL 5003 sapphire blue Control cabinets and small casings in "light grey" The base configuration of the machine includes two initial equipment belts (W x L) 150 x 9000 mm and a contact roller approx. 50° Shore for 150 mm belt width.
