The KERN Pyramid Nano has been developed for applications which require maximum accuracy and surface finish on larger workpieces (>Technical Data). An integrated automatic workpiece changer allows unmanned operations even for 5 axes simultaneous jobs . Hydrostatic drives and guideways of the X-, Y- and Z-axes allow maximum surface finishes in nano precision.

Specific machine characteristics:
Positioning scatter Ps ± 0.3 µm
Surface finish Ra 0.05 µm
Acceleration 10 m/s2 (1 g)
Feed rate 30 m/min
Digital CNC precision dividing head with torque drives for
   high dynamics when milling 5 axes simultaneously
Vector-controlled milling spindle HSK 40 with oriented tool change
   Option: coolant through the center of the tool
Vector-controlled milling spindle HSK 25 with oriented tool change
Automatic tool changer HSK 40: 25, 50 or 75 positions
Automatic tool changer HSK 25: 32, 64 or 96 positions
Integrated workpiece changer with up to 20 positions (max. 70 x 70 x 150 mm)
Alternatively: External workpiece changer (pallet max. 300 x 300 mm)
Automatic tool measuring by laser for length, radius and concentric accuracy
Automatic workpiece measuring with a touch probe system and infrared
   data transmission
Milling in hardened steel (up to 64 HRC)
Machining of graphite and ceramics
KERN ARMORITH machine base giving optimum vibration dampening
Hydrostatic axes guideways
Hydrostatic drives
Integrated central temperature management for constant cooling of spindle,
   hydraulic system, electrical cabinet and flood coolant unit
Integrated associated facilities provide a compact machine
Jig-grinding cycle as option

The KERN Pyramid Nano can be configured individually according to the customers requirements with a wide range of accessories and options.
