Title:
HIGH-ROTATIONAL SPEED CUP-SHAPED GRINDING WHEEL
Document Type and Number:
WIPO Patent Application WO/2021/197027
Kind Code:
A1
Abstract:
A high-rotational speed cup-shaped grinding wheel, comprising an annular base body (1) and several blades (2); the blades (2) are fixed on a side of the base body (1) at intervals in a circumferential direction to form a blade ring, the side of the blade ring away from the base body (1) forms an annular working surface, and two adjacent blades (2) are spaced apart from each other to form a water passage channel (3) for delivering cooling water to the working surface. The high-rotational speed cup-shaped grinding wheel further comprises a flow splitting structure; the flow splitting structure is fixed on the blade ring and splits the cooling water into two branches, wherein the first branch deliveries the cooling water to an area outside the working surface through the interior of the water passage channel (3), and the second branch deliveries the cooling water to an area inside the working surface through the exterior of the water passage channel (3), and then deliveries the cooling water from the area inside the working surface to the area outside the working surface. When rotating at a high speed, the cup-shaped grinding wheel can use a centrifugal force to split cooling water in the base body into two branches, thereby achieving full coverage of the working surface by cooling water, and ensuring cooling water required by the cup-shaped grinding wheel during machining.
