Abstract: An orderly-micro-grooved PCD grinding wheel includes a wheel hub, a polycrystalline diamond (PCD) film, a number of micro-grinding units and a number of microgrooves. The PCD film is deposited on an outer circumferential surface of the wheel hub. The PCD film is processed by a water-jet guided laser device to form the microgrooves with high depth-width ratio and micro-grinding units with positive rake angles on the entire outer circumferential surface of the PCD film. An axial length of each micro-grinding unit and an axial length of each microgroove are equal to a thickness of the grinding wheel, respectively. The microgrooves are spaced apart by the micro-grinding units.
