The external whirling machine LWN 120 can be used universally and fulfills even the highest demands. Thanks to a torque motor, the machine is designed for high-speed cutting (up to 10,000 1/min). Together with its high machine rigidity, these are the ideal conditions for economical use in finish hard machining. The wide swiveling angle (±50°) makes it possible to finish almost all thread profiles and screws.
