Abstract
A flat-sided annular blade for a blade ring saw for cutting hard materials such as tile along straight paths and curved paths in which the workpiece is moved through the central portion of the blade. In addition to the usual sintered abrasive diamond coating on the outer peripheral portion of the blade, the inner peripheral portion preferably is tapered to a curved inner edge and also is coated with an abrasive, preferably an electroplated diamond coating providing smoother sawing operation and a finishing action on the workpiece.
Claims13
A blade ring saw blade for making straight and curved cuts in hard workpieces, the blade comprising:
- an annular body having an outer peripheral edge, an inner peripheral edge defining a large central opening for relative movement of the workpieces through the blade during making of curved cuts, a portion of reduced thickness forming a rib extending outwardly from the outer peripheral edge around the body, and substantially flat sides that are substantially wider than the thickness of the edges, the substantially flat sides extending generally radially for providing increased radial strength to the blade to enable driving the blade at high speeds through the workpieces;
- and
- an abrasive coating extending around the outer peripheral edge of the body and forming an outer peripheral cutting element for the blade for making the curved and straight cuts in the workpieces, the abrasive coating further covering the flat sides and inner peripheral edge of the body to form an inner peripheral cutting element for finishing curved cuts in the workpieces and providing smoother action as well as for cutting reversely, the inner peripheral edge and the coating thereon defining an open central portion of the blade permitting the workpieces to be turned relative to the blade to make the curved cuts.

- and
- an abrasive coating encapsulating the body to define an outer peripheral cutting element and an inner peripheral cutting element and sidewalls extending therebetween, the sidewalls are substantially parallel adjacent the outer peripheral edge and taper inwardly adjacent the inner peripheral edge, the outer peripheral cutting element extending along the outer peripheral edge of the body for finishing curved cuts in the workpieces and providing smoother action as well as for cutting reversely, the inner peripheral cutting element extending along the inner peripheral edge of the body and defining an open central portion of the blade permitting the workpieces to be turned relative to the blade to make the curved cuts.
