OERLIKON C28

Face Hobbing - Continuous Process: The workpiece and tool (usually Spiron) rotate simultaneously, and all teeth are produced in one operation. The cutter head has several cutter groups (not arranged in a circle). Features include: parallel tooth height and a conical tooth face. Single-part process: The workpiece is stationary, and the tool (usually Arcon) rotates and cuts a tooth by plunging the tool. Once a tooth is cut, the tool moves out of the tooth, the workpiece cuts another tooth width, and the next tooth is cut, until all teeth are finished. The cutter head has all cutters arranged on a circular path. Features include: conical tooth height and a parallel tooth face. The C28 can handle both gear and pinion machining. However, for the single-part process, a C28 must be "prepared." This means it needs a direct measuring system, a part-gear brake, a workpiece axis, and a license file for manufacturing the single-part process.
