The roughing operation is easy and the shortened diameter of the steel brush allows a good roughing of the waist too. The width of the surface to be roughed is adjustable from mm 4 to mm 22. A set of flange to apply on the brush sides avoids the skirting
during the work. To rough closely hides it’s also possible to use a roughing washers device (optional). Through a pneumatic pedal the guide moves, to allow irregular roughings. The machine must be connected to a suction central system or to an exhauster.
