The perimetral deburring unit is composed of an identification system of the geometrical shape of the workpiece to be deburred. It is controlled by a PLC which activates a series of pneumatic sections (with 32 mm or 16 mm definition) that apply the necessary pressure on the abrasive belt on the perimeter of the workpiece only, thus removing the burrs, or in all geometric shape for a perfect finishing also on uneven surfaces. The advanced system management via PLC allows to vary the amplitude and the pressure of the working area as required.
