The sanding centre SZ 2 for the first time allows a processing of irregularly shaped contours with belt sanding units. Desk tops with rounded edges as well as 3-dimensionally shaped parts in the automobile industry for decorative interior panelling can be sanded. By means of the use of sanding belts an even surface quality, a considerably longer life time of sanding material and a tolerance compensation for the edge processing are achieved. The main feed axis and turning axis necessary for the movement of the workpiece are integrated in the flat designed machine table. The result is a decisive advantage in stiffness in case of high dynamical feed forces. In comparison to articulated-arm robot-systems. A high precision of the movement in case of high path velocities reduces the processing time. Programming of the SZ 2 is made by a Windows surface. The workpiece contours can be entered via DXF files from CAD or by a scanning process. Setting-up is made by means of two clamping devices parallel to the main period.
