A method and a relative plant, differently from the known approaches, contemplates the fabrication of planar "biscuits", press consolidated at room temperature, thus avoiding the problems and criticalities connected to the use of cup-shaped molds for producing grinding wheels with a depressed center, and a press shaping workstation of the "biscuit" (planar wheel not yet hardened) between a mold and a countermold, shaped in order to impress the so press consolidated "biscuit", but not yet hardened, the desired depressed center shape. <IMAGE>
