<p>This invention relates to an assembled hob cutter for machining involute dented articles, wherein said hob cutter comprises throw-away, rotating and replaceable cutting plates. The cutting plates are mounted on the tips, in the central parts and on the roots on the profile plane of successive teeth. The cutting edges of these plates include modified sections conforming to the profile of a given section of the cutter tooth, and overlap over the gaps between adjacent plates. The plates can be mounted on a tooth so as to rest one on the other or sequentially one after the other. A round or five-sided plate can be mounted on the tip of the tooth, while a hexagonal plate can be mounted in the central part and a triangular or quadrangular modified plate can be mounted on the root of the tooth. Hexagonal plates can be mounted on the tip, in the central part or on the root of a tooth, while the plates mounted on the tip and in the central part of a tooth can be combined into a single plate.</p> |
