Ogden says the NBS 800 CNC grinder is ideal for sharpening stellite, bimetal and carbide-tipped circular saw blades up to 800mm in diameter.  It uses a diamond or ceramic grinding wheel and a water-cooling system.  A driven diamond dressing wheel automatically cycles to keep the shape of the grinding stone clean and consistent.
