Optimal Prototyping Instrument
Based on the structure and axis kinematics of the G 500 H, the GR version of the machine is specifically equipped for the manufacturing of rotors. The single grinding spindle allows the operator to grind small to medium lots with unmatched quality, making the GR 500 H an optimal prototyping instrument. Equipped with dressable corundum wheels, integrated dressing and measuring units profile deviations can be auto-corrected immediately.
For larger lot manufacturing we recommend the connection of the machine to an external measuring unit, allowing for maximum efficiency and best results. The GR 500 H comes equipped with a specific rotor software package developed under real rotor manufacturing conditions.
The specific strength of the GR 500 H shows in the flexible manufacturing with dressable corundum wheels. For surface structure requirements and higher speeds you can use CBN grinding wheels as well.
