Features
The FGC 2 machine features both profiled diamond roll and rotary diameter disk dressing capability, providing quick and efficient set up. The machine can also be supplied with a double dresser capability for multiple and extended machining operations, providing even greater productivity levels. The dressing facility enables the economic and precise dressing of complex fir tree root forms and shroud end features - from initial profile dressing through to in-cycle wheel dressing.
Coolant is supplied by a unique, fully programmable / steerable twin nozzle arrangement. This assures that coolant is continually supplied as near to the cut as possible and that the wheel is always clean and sharp. Results suggest a saving of 30% on wheel life compared to a standard, single nozzle type machine.
The FGC 2 grinding centre can be supplied with a unique media-free coolant filtration system. This system is both environmentally friendly, highly efficient and helps reduce operational and overhead costs. This media-free option totally eliminates filter paper consumption.
We understand the need to maximise productivity in a high pressure manufacturing environment. The FGC 2 machine therefore has an automatic wheel change capability which keeps productivity high and wheel change related downtime low.
Easy to use, operator friendly and simple to program 3,4 and even 5 axis simultaneous machining of components using on screen graphics. This also includes the positioning of the programmable twin coolant nozzle system.
