Some problems existing in present grinding machines are analyzed, and a new type of CNC grinding machine is presented. As the feed system of this grinding machine is a parallel mechanism driven directly by linear motors, some traditional transmission forms are not required, such as the ball lead screw pairs, the gears, the hydraulic transmission device, etc.
