The ZF Duoplan Two-Speed Gearbox is mainly used in machine tool main-spindle drives, test benches and applications where tigh torque is needed. Machine tools are designed to be universal so that they can process different materials. This requires both high cutting speeds for soft materials as well as high cutting forces for harder materials. The two-speed gearbox can fulfill this requirement since it can either retain high motor speeds (i = 1:1) or multiply the motor torque (e.g. i = 4:1) and reduce the speed, both by the same factor.
