This machine is designed for continuous operation at high machining speeds and features quiet operation, maximum accuracy and minimal heat-buildup for guaranteed optimum work results
Dual guides for linear table motion
Grinding spindle head and Z-axis run in precision linear guides on preloaded ball screws
Servo drives on Y and Z axis and hydraulic linear table movement can be adjusted via an infinitely variable electronic proportional valve for precise and consistent feed
3-step electronic hand-wheel allows for precise positioning of the Y and Z axis
The grind spindle head features a heavy, solid design and runs on high-precision, maintenancefree preloaded angular ball bearings
External hydraulic unit and large oil cooler ensures thermal stability
Automatic central lubrication system

Intuitive dialog-guided programming for automatic and semi-automatic grinding and dressing of grinding wheels, optimized for surface grinding
Programming of grinding cycles via touchscreen
Easy adjustment of important parameters and feed rates during machining
Automatic function monitoring and error messages on the display
