Technology
When we talk about high production, every detail matters
Lg technology
Built-in spindles
  • Direct-drive workhead spindle, grinding wheel spindles and dressing tool spindles
  • High precision bearings with lifetime grease lubrication and temperature control
  • Suitable for high rotational speed
Natural granite bed

Natural granite is one of the keys for achieving the highest accuracy and the best surface quality.

  • Thermally very stable
  • Coolant through the bed and grinding area
  • Outstanding vibration damping properties
  • Environmentally friendly
Swivellingaxis
  • High resolution swivelling B axis, infinitely programmable
  • Torque motor driven for zero backlash
  • High resolution rotary encoder to control angular positioning
Linear motors
  • X and Z axis linear motor drives, allowing for highly dynamic axis movements
  • Drive function with no mechanical contact, resulting in no wear and low maintenance
  • Ultra precision positioning and repeatability
Customization
