The wafer cutter is a coated one way tool, which represents the optimum tool status - comparable to a spur toothed shaping cutter. The thin, coated wafer disc is clamped in a special wafer holder and mounted on the shaping cutter holder of the shaping machine like a shaping cutter. Advantages: - Maximum process reliability - Economical in mass production - No changes in the gear profile as a result of wear - Very easy machine adjustment (reduced setup time) - Fully coated tools always in use - Machine adjustment after wafer change not required during one series of workpieces
