Title:
GRINDING WHEEL TOOL FOR MACHINING MICRO-GROOVE, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/210481
Kind Code:
A1
Abstract:
A grinding wheel tool for machining a micro-groove, comprising a grinding wheel tool body (10). The grinding wheel tool body (10) is formed by sequentially stacking multiple thin grinding wheels (11) in the thickness direction of the thin grinding wheels (11). The initial diameters of the thin grinding wheels (11) are the same. Slots (101) make the outer circumferences of the thin grinding wheels (11) different. A thin grinding wheel having a large outer circumference wears slowly, and a thin grinding wheel having a small outer circumference wears quickly. For grinding machining of micro-grooves having the same depth, a machining end face (12) of the grinding wheel tool body (10) would eventually be formed into a stable contour shape. Moreover, the outer circumferences of the thin grinding wheels (11) can be adjusted by the slots (101) to form different contour shapes. Also provided is a manufacturing method for the grinding wheel tool for machining a micro-groove. The grinding wheel tool has self-trimming ability and thus can always maintain the contour shape of the machining end face, and frequent sharpening and trimming are not needed, thereby effectively improving the grinding efficiency and machined shape accuracy. Micro-grooves of different shapes can be machined.
