Method of chopping with bird's nest-like grindstone and bird's nest-like grindstone

摘要

To provide a novel and improved grinding method capable of improving grinding efficiency by minimizing grinding scraps, improving the efficiency of the coolant in the grinding stone, increasing the discharge efficiency of the grinding scraps, and shortening the grinding time in penetrating the holes from the thin plate to the thick plate (Referred to as a bird's nest-like grinding stone) and this chopping processing technique.SOLUTION: A wire mesh body 4A is formed by forming a core material body 3 into a cylindrical shape and provided with through holes h in the core wire, and bird's nest-like grinding in which abrasive grains D are fired or electrodeposited on the surface of the wire mesh body And the grinding fluid GO or the coolant liquid CO press fitted in the through hole in the rear end core wire of the wire mesh body reaches a group of cutting edges fixed to the tip of the wire mesh body, (Abrasive grain) D of the wire mesh body which has been opened.BACKGROUND OF THE INVENTION
