These vibrating machines have been designed for deburring, smoothing or polishing of parts by means of plastic, ceramic or wood abrasives.

They have the particularity of being able to invert their direction of rotation, clockwise for the work cycle and counterclockwise for unloading.

When the direction of rotation is changed, the discharge paddle plugs the entire mass of chips and parts, forcing it upwards and passing it through the discharge grate, thus separating the parts and abrasives.
