G300 OD Grinder
High precision CNC Cylindrical grinding

The Weldon model G300 is a mid-sized CNC cylindrical grinder designed specifically to produce high precision parts either between centers or in a chucking mode.

Although capable of running in a high production environment, the G300 also provides the flexibility to grind a wide variety of part configurations with minimal set-up.

Available with either a straight or angular wheelhead (factory set) the G300 can grind outside diameters, shoulders and faces in a single set-up. The CNC control can address complex form grinding (tapers, radii, etc.) via form dressed wheels or profiling.
