The present invention provides a hobbing machine. The hobbing machine includes a clamp fixture adapted to retain a gear blank. A motor is operatively connected to the clamp fixture and is configured to rotate the clamp fixture and the gear blank together at a predetermined speed. A rotatable cutter is translatable into engagement with the gear blank and is configured to cut the gear blank and thereby produce a plurality of gear teeth. A de-burring tool is translatable into engagement with the gear blank and is configured to remove burrs from the gear blank as the gear teeth are being cut. A motorized spindle is operatively connected to the de-burring tool, and is configured to power and rotate the de-burring tool at a predefined speed to optimize the removal of the burrs.

A work piece having edges comprising teeth, slots, dovetail, keyway or other irregularly shaped artifacts, can be provided with a uniform chamfer around the periphery of the work piece by bringing a grinding wheel or cutter in one single down feed at indexed intervals. The shape or profile of the grinding wheel or cutter is formed from an algorithm depending on the shape and dimensions of the work piece artifacts, such as gear teeth, etc., to provide the uniform chamfer at each slot of, for example, an internal or external gear wheel. A method of providing such a chamfer on irregularly shaped artifacts comprises forming a gear grinding wheel from the dimensions of the desired chamfer, and providing a chamfering tool or grinding wheel in accordance with an algorithm desired for the required chamfer, then bringing the gear chamfering tool in proximity to, and in contact with the edges of the work piece so as to produce a uniform chamfer on the sides and back edge. The method may include a step of moving of the cutter or grinding wheel from one side to another and tilting the cutter or grinding wheel to chamfer the back side.

A method for the precision working of the tooth flanks of particularly hardened gears (workpiece W) with a gearlike tool, the tooth flanks of which tool have an abrasive surface and which rotates in mesh with the workpiece (W). In order to avoid damage to the tool caused by remaining burrs or the like in the tooth system of the workpiece (W), a twin tool with axially spaced similar tools is utilized, individual ones of the similar tools are used one after the other. The first tool removes thereby first the remaining burrs and the like and the second tool performs thereafter the actual precision working.

A bevel gear set and a method of manufacturing the same are provided. The bevel gear set may include a first bevel gear and a second bevel gear. The first and second bevel gears may be spiral bevel gears or hypoid spiral bevel gears. The first and second bevel gears may each have a gear tooth surface having a plurality of teeth formed thereon, such that the teeth of the first bevel gear and the teeth of the second bevel gear are configured to engage in a meshing engagement. The teeth are machined onto the respective gear tooth surface via a face milling process. Each tooth includes a tooth top, a plurality of meshing surfaces, and at least one chamfer. The chamfer may be formed at an abutment edge disposed between the tooth top and a respective meshing surface via a brushing process directly following the machining of the teeth.
