  • High ergonomics by free access and view onto the workpiece
  • Flexible with the table height adjustment
  • Simple adjustment of grinding belt speed and pressure for belt tensioning
  • Automated reduce of grinding belt speed by pushing the grinding belt cover, no further manual setup required
  • Simple control of handling functionality by foot operation panel
