3 pressure beams with computer-controlled CSD® selective pressure control system
with infinitely variable pressure adjustment of the individual pressure elements, for free, multi-track feeding. Spacing of the control rollers 32 mm. Workpiece tolerance compensation up to max. 2 mm by maintenance-free pressure magnets. Working width as well as start and end of grinding of the pressure beam are electronically controlled.
While a workpiece is running through the machine, the pressure elements enable stepless regulation of the pressure force of each individual pressure shoe by means of electric lifting magnets. This innovative CSD® technology guarantees
proportionally equal pressure at all times with regard to the contact area of the pressure shoe on the workpiece. This infinitely variable, dynamic control of the pressure force virtually eliminates the risk of grinding through at the edges. In addition, the electromagnetic CSD® system is maintenance-free, as there is no possibility of contamination as with pneumatic elements.
