Surface grinding

KUHLMEYER Belt Grinding Machines to grind surfaces on plates, sheets or formed and welded three dimensional components.

Portal Twin-Belt Grinding Machine Type PZM

The PortalTwin-Belt Grinding Machine is built for the roughing and finishing  on welded edges, corners and surfaces on flat and bulky workpieces out of steel, stainless steel, and aluminum, i.e. cabinets, housings, hoods, furniture parts, frame parts in automotive-, aircraft- and train manufacturing, cylinders , heater, tubes etc. 

Application areas:

  • Machinebuilding industry
  • Automotive- and aircraft industry
  • Machinebuilding industry
  • Automotive- and aircraft industry

.

  • Electrical cabinet production
  • Steelwork / Steel-service-center

Options / Variations:

  • Motorized horizontal axis to move the grinding unit for 650 mm
  • Tool-Automation with additional motorized axes
  • Add. contact drum 
  • Workpiece handling device, manually (incl. additional F/B – rotate and swiveling unit with brake system)
  • Scissor lifter (w/ or w/o motorized drive unit)
  • Rotate- and turnover units motorized with a separate carrier
  • Add. machine table and storage (stationary or movable)
  • Dust exhaust for different materials
  • Robotec-Handling (automated, motorized)
  • Very bulky and voluminous parts, which are longer then the working area of the machine, will be placed directly on the motorized lifter table
  • For the work on smaller parts on the lifter platform, a small and light movable table can be placed or a separate Handling device can be activated

Advantages of the Twin-Belt Grinding Machine Type PZM:

  • 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
