  • The mineral-casting frame dampens vibrations 6 times faster than cast-iron (GG25) and up to 10 times faster than steel
  • Further advantages of this machine are its quiet operation, maximum accuracy, and low heat accumulation
  • This design allows superior evenness of ground surfaces and a dimensional stability that could not be achieved with conventional machine designs
  • In addition to its vibration-proof solidity, this material also provides excellent thermal stability
  • Linear roller guides on all axes ensure excellent rigidity, accuracy, and optimum load distribution
  • Powerful servo-drives and preloaded ball screws on all axes ensure a uniform feed
  • A specially selected preloaded ball screw provides for a higher accuracy class (C2), and a manually read linear scale complements the vertical axis drive
  • All axes can be positioned precisely via an electronic hand-wheel
  • The grind spindle head features a heavy, solid design and runs on high-precision, maintenance-free preloaded angular ball bearings
  • Automatic central lubrication minimizes maintenance
  • Optional vacuum clamping fixtures are available for custom applications/materials
  • Siemens 828D control with grinding package, trueing cycles, and profile grinding function
