Advantages of the Twin-Belt Grinding Machine:

  • Savings of approx. 50% on working time by use of the 2 separate grinding belts for roughing and finishing: Only one handling and setup of the workpiece
  • Further savings of approx. 25% by use of the handling device: The workpiece can be orientated on 5 axes and can be prepared on all sides in one operation
  • Manually preparation and pre-grinding on welded seam can be avoided, because the grinding belts can be tensed very smooth and then rotated by 90°. The operator can reach almost all edges and corners of the workpiece and polish the surface
  • High ergonomics by free access and view onto the workpiece
  • High safety by always accessible E-Stop-String
  • Flexible with the Grinding unit - height adjustment
  • Simple adjustment of grinding belt speed and pressure for belt tensioning
  • Simple control of handling functionality by foot operation panel 
  • Fast and simple grinding belt changing by self-centering belt run
  • Many additional features for safe handling can be adapted or integrated
