Method for producing a green body for a machining segment (51) from a powdered or granular first matrix material (56) and first hard material particles (57), the machining segment being connected by an underside (61) to a basic body of a machining tool. The machining segment (51) has a projection (Δ) of the first hard material particles (57) on an upper side (62) opposite from the underside (61).

A harvesting knife has a base body, which is configured to be applied in a manner rotating in a machine around a drive rotational axis allocated to said base body, and has a plurality of teeth on its circumference wherein, prior to a first application, at least one of the teeth has at least one cutter formed thereon.

The invention relates to a method for joining hard material bodies to teeth of a saw blade, in particular of a band saw blade or circular saw blade, wherein each tooth has a tooth face and a tooth back, and the method includes the following steps: bringing each tooth of the saw blade into a working region; guiding each hard material body toward the tooth located in the working region; advancing a joining device into the working region; joining the hard material body to the tooth located in the working region; and withdrawing the joining device out of the working region. According to the invention, each hard material body is joined to the tooth back of each tooth.

There is provided a base-integrated blade manufacturing method for manufacturing a base-integrated blade by fixing a cutting blade having a circular opening to a base having an annular projection. The method includes a first step of preparing the base having the projection that has an outside diameter greater than a diameter of the opening of the cutting blade, and the cutting blade, a second step of lowering a temperature of the base and thus shrinking the base to have the outside diameter of the projection smaller than the diameter of the opening of the cutting blade, a third step of inserting the projection into the opening of the cutting blade, and a fourth step of raising the temperature of the base and thus expanding the base in such a manner that the cutting blade is fixed to the base.

A saw blade including a body, a plurality of cutting teeth, and a plurality of gullets. The plurality of cutting teeth formed on the body. Each cutting tooth includes a first end and a second end. The plurality of gullets is formed between the plurality of cutting teeth. Each gullet having an opening defined between the first end of one tooth of the plurality of cutting teeth and the second end of an adjacent tooth of the plurality of cutting teeth. Each opening has an opening width and a gullet width. A ratio between he gullet width over the opening width is greater than or equal to 1.2:1.
