Abstract: A grinding wheel tool for microgroove processing and a method for fabricating a microgroove, including a grinding wheel tool body. The grinding wheel tool body is formed by sequentially stacking a plurality of grinding wheel sheets along a thickness direction of each of the plurality of grinding wheel sheet, and the initial diameters of the individual grinding wheel sheets are the same. The outer edge circumference of each grinding wheel sheet is different due to notches, the grinding wheel sheet with a large outer edge circumference wears slowly; the grinding wheel sheet with small outer edge circumference wears fast. For the grinding process of microgrooves of the same depth, the processing end face of the grinding wheel tool body will eventually form a stable contour shape, and the outer edge circumference of each grinding wheel sheet can be adjusted by notches to form different contour shapes.
