Abstract: This invention relates to a super abrasive grinding tool element and grinding tools having the element, the element being formed by bonding, with a resin system adhesive, super abrasive grains of diamond or the like to a mesh base so that the openings of the mesh base are kept open. In the element, there is sufficient cutting edge projection, a sufficient amount of coolant can be supplied, clogging is unlikely to occur, and high cutting efficiency can be maintained for a long time.
Abstract: In an anti-clogging device, an opposed member is provided to be opposed to the grinding surface of a grinding wheel over a predetermined length with a fine space therebetween. During grinding, cutting eliminating liquid is fed into the fine space between the opposed member and the grinding surface from the end facing in the direction opposite to the rotating direction of the grinding wheel to prevent the grinding surface from being clogged with cuttings.
