The invention relates to a mechanical equipment, namely a grinding wheel layered digital manufacturing device. The invention is characterized in that the device consists of a mechanical part and a computer control part. The mechanical part consists of a platform 7 used for bearing a work piece, an operation part and a slide way used for movement of the platform 7 or the operation part, etc. The operation part comprises a raw material box used for feeding raw materials to the platform 7 and a laser generator 13 used for sintering and forming the raw materials. When in work, various technical parameters are transmitted into the computer control system ahead, and then under the control of a computer program, the grinding wheel raw materials are layered and put on the platform and are sintered into shape by a laser. The granule position of the grinding material of the grinding wheel manufactured by the device is accurate, and the protruding height can be controlled. The scraps-containing room is proper and the solidified strength is enough, and the later finishing can be avoided and the shape can be randomly selected. The manufacturing cost is low and the service life is long. The grinding heat loss can be largely reduced by the device and the device can meet high processing accuracy and high manufacturing efficiency requirement. The invention provides suitable equipment for realizing the digital manufacturing of the grinding wheel.
