gemini NGM

5-axis CNC grinding machine with high performance and autonomy for the serial production of end mills, drills, profile tools, profile grinding of pinion cutters and hob peeling cutters, as well as production grinding tasks such as profile grinding and flat grinding.

The geminiNGM is the 5-axis CNC grinding machine for the serial production of cutting tools. Complete processing around OD and face, up to 300 mm cutting length, diameter up to 300 mm, maximum workpiece length that can be clamped 500 mm.

Cutting tools such as end mills, ball nose cutters for mold making, high-performance drills, reamers and profile end mills are all part of the standard requirement.

There are specific software packages, grinding processes and clamping systems for the production of shaper cutters with highly dynamic segmented hob grinding, the regrinding of gear cutting tools, end mills, shaper cutters and bevel gear cutters.

CNC grinding of knives for the paper, foodstuffs and plastics industries, profile grinding, cylindrical grinding and surface grinding.

Numerous accessories for the application spectrum and for increased productivity:

  • 6-axis robot for workpiece loading with capacity for 2, 4, or 10 pallets
  • Laser marking of the workpieces
  • Grinding wheel loader with 8 or 14 grinding wheel packages incl. coolant manifold
  • Direct measuring system in all axes
  • Linear motors in all axes
  • Hollow shaft motor for cylindrical grinding tasks
  • Dressing unit for dressing profiles and sharpening
  • Manual or hydraulic tailstock
  • Manual, hydraulic or CNC controlled steady rest, following the point of grinding
  • Collet chucks, clamping mandrel, turning plate holder
  • Coolant filtration system
  • Exhaust air filter
  • CO2 extinguishing system
