  • the known method for controlling a wall sawing system is divided into a preparatory section and a processing of the separating cut, which is controlled by the control unit.
  • the operator defines at least the saw blade diameter, the positions of the first and second end points in the feed direction, and the final depth of the separating cut; further parameters can include the material of the workpiece to be processed. workpiece and the dimensions of embedded reinforcing bars.
