A valve angle grinding machine built to bring the valves of a cylinder head under overhaul back into service. The valve is centred between points and clamped; the graduated table is locked to the required angle, and the valve face is passed across the wheel.
Circulating coolant is directed into the cut throughout, so the face does not burn and the wheel lasts longer. The wheel itself is re-profiled by the diamond dresser mounted on the body, without coming off the machine.
