Condition: ready for operation (used), Year of construction: 1998, functionality: fully functional, machine/vehicle number: 291127, wheel diameter: 275 mm, wheel width: 55 mm, controller manufacturer: Siemens, controller model: 840 C, Face Milling - Single Part Process - Continuous Process: - The workpiece and tool (usually Spiron) rotate simultaneously, and all teeth are machined simultaneously in a single operation. - The cutter head has multiple cutter groups (not arranged in a circle) - Parallel tooth height - Conical tooth tip surface 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 back out of the tooth, the workpiece continues to cut by one tooth width, and the next tooth is cut until all teeth are finished. - The cutter head has all cutters arranged on a circular path. - Conical tooth height - Parallel tooth tip surface The C28 can handle both gear and pinion. For the single part process, a C28 must be "prepared" - i.e., a direct measuring system + part gear brake, workpiece axis + license file for manufacturing single part processes.
