GRX 500 H Rotor and Worm Grinding Machine

The GRX is a larger and stronger version of the GR. Its powerful twin spindle and extremely stabile bed design make it a must for the manufacture of very large screws and rotors. Especially adapted to grind with CBN, the GRX also makes working with dressable ceramic wheels or even combinations of the two easy.

An integrated measuring unit also makes the correction of rotor prototypes and pre-production pieces more straightforward. For more efficient handling, you can link the GRX to an external robot device and connect it directly with an external measuring unit. Like the GR, the GRX comes with a rotor-specific software package, developed under real manufacturing conditions.
