- 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, maintenancefree 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
