Advantages of the Portal Belt Grinding Machine Type PBM:

  • Due to the build with the gantry style machine frame and floor clearance, especially bulky and tall pieces can be machined
  • Even heavy weight workpieces (up to 3 tons) can be easily and proper machined
  • By the clearance in horizontal and vertical movement the workpieces can easy and safe adjusted on the scissor lift
  • With the rotatable grinding unit of 0°-90° the workpieces can be machined in one setup on back and top side (horizontal and vertical), which saves a marginal time in adjusting and set-up-time
  • Use of the optional rotate turnstile will save another portion of set-up-time due to the work on all 4 sides and top in one hit
  • With the motorized adjustable angel of grinding unit, even steps and edges can be grinded easily and also the rounding of sharp edges is possible
  • High accuracy of grinding unit angle with +- 0,3°
  • Manually grinding on extreme areas is possible by loosening the tools from the automated guiding system
  • Easy setup of grinding belt speed and pressure
  • Easy control and programming of handling by PLC and R/C handheld
  • Fast and simple grinding belt changing by self-centering belt run
