The MB4 is equipped with one bottom and one top XVS multifunction brushing units for all deburring operations and oxide removal, in a single pass. These units are composed by a series of vertical brushes, rotating at high speed (inverter controlled) and oscillating side-ways at adjustable rate of oscillation. Combining the vertical axis rotation with high frequency oscillation, allows to achieve a perfect deburring in all directions with a single working unit. The XVS units are extractable to allow an easy tool change and regular maintenance. They are prepared to operate with standard low-cost brush cups, as well as more specialized custom brushes
