A prior art grinding assembly a gin blade sharpening system for sharpening a blank into a blade disk. The gin blade sharpening system comprises two or more grinding stations, a controller, and one or more upper grinders. The one or more upper grinders comprise at least a first upper grinder. The two or more grinding stations comprise at least a first grinding station and a second grinding station. each among the two or more grinding stations comprise a clamp assembly configured to selectively hold the blade disk in a substantially horizontal position. a portion of the one or more upper grinders can be configured to sharpen an outer perimeter edge of the blade disk using an abrasive pad.

The invention proposes a tipped circular saw blade (10) comprising a saw body (11) with a peripheral circular region made of a first material, the peripheral circular region having a plurality of slots (12), and a plurality of tips (13) made of a second material, each tip (13) fixed to a respective slot (12) to form a saw tooth (14) defined between an anterior gullet (15) and a posterior gullet (16), each saw tooth (14) having a cutting edge (141). In accordance with the invention, each saw tooth (14) has a leading face (142) defined between the anterior gullet (15) and the cutting edge (141), the leading face (142) having a profile that includes a single curved surface formed by an R radius, the curved surface encompassing the first material and the second material. The invention further proposes a method of manufacturing a tipped circular saw blade (10), the method comprising a step of forming a saw body (11) with a peripheral circular region made of a first material, the peripheral circular region having a plurality of slots (12); a step of joining a plurality of prefabricated tips (13a), made of a second material, to the respective slots (12) of the peripheral region of the saw body (11), obtaining a preliminary tipped circular saw blade (10a); and a step of grinding the preliminary tipped circular saw blade (10a) to form a plurality of saw teeth (14), each saw tooth (14) defined between an anterior gullet (15) and a posterior gullet (16), and having a cutting edge (141) and a leading face (142) defined between the anterior gullet (15) and the cutting edge (141), the leading face (142) having a profile that includes a single curved surface formed by an R radius, the curved surface encompassing the first material and the second material.

The present invention is part of machine tools that today are widely used in all mechanical workshops, often being designed and built also to perform very specific tasks.

In particular, the present invention relates to the processing of discs for circular saws or saw-disks.

A dressing method of a cutting blade includes a first cutting step of causing the cutting blade to cut into a dressing board held by a holding surface of a chuck table with a cutting depth that does not surpass the length of the region of roundness in the radial direction of the cutting blade to form a cut groove in the dressing board, and a second cutting step of causing the cutting blade to further cut into the groove bottom of the cut groove formed in the first cutting step with a cutting depth that does not surpass the length of the region of roundness in the radial direction of the cutting blade to carry out cutting on the groove bottom with tracing of the cut groove.
