Abstract:
The present invention relates to a blade ring saw assembly (10) in which the blade (19) is a narrow, flat-sided metal ring having a radial width at least twice, and preferably four to six times, its thickness and has a diamond abrasive coating (23) covering its outer peripheral edge (24) and a portion of each sidewall of the ring. The blade ring (19) is supported on a base (15) from beneath the working surface, and projects upwardly to expose more than one-half of the blade ring (19) for cutting of hard and thick workpieces (14), such as tile and stone, including both curved cutting and straight cutting. The blade ring (19) is supported beneath the work surface by a plurality of roller guides (29) above its radially inner edge and an endless drive belt (34) having a run that extends beneath the blade ring so as to both support and drive the blade ring (19).
