A tool for hob peeling rotating workpieces having pre-machined teeth comprises a gear-wheel shaped main body and tooth-shaped cutting inserts () which at the end face in the region of the tip circle are disposed on the main body. Each cutting insert comprises at least one cutting tooth. The cutting tooth forms a cutting edge () which runs at least along one of the flanks of the cutting tooth, and a cutting face and a clearance face. The cutting face along the cutting edge is provided with a cutting face chamfer () which in relation to the cutting face () runs so as to be inclined by a chamfer angle. The chamfer angle varies along the cutting edge. Moreover, the cutting edge is rounded by a radius.

Hob peeling tool and method for hard-fine machining of pre-toothed workpieces

Dressing tool including a main body having a working surface covered with hard-material grains distributed on the main body. Recesses for accommodating the hard-material grains are created in the main body and then filled with an adhesive, the excess adhesive is removed across the main body, and thereafter the hard-material grains are flung onto the main body so that only the grains located in the recesses remain adherent to the working surface of the tool. The hard-material grains can then be bonded to the main body by a physical and/or chemical bond. Thus, a distribution of the grains over the working surface of the tool that can be precisely defined in advance is ensured.

Dressing tool and method for the production thereof

Method for reinforcing a grinding wheel, preferably for grinding gears. By means of at least one plastic that is poured in, both a ring lining a bore of the grinding wheel and a reinforcing layer are formed in the grinding wheel pores. The plastic that is poured in preferably consists of a potting compound, used in the raw state, made of a 2-component polyurethane system. In order to produce the reinforcement, the grinding wheel is set rotating, i.e., rotated, and, at the same time, a specific quantity of potting compound is poured into the bore. An increase in the explosion speed during operation of the grinding wheel is thereby made possible.
