This Liebherr LC-482 Gear Hobbing Machine has a Liebherr Controls System, along with Indramat servo drives and motors. This machine is unique in that it incorporates a two (2) position ring loader/unloader (ring magazine). Once the part is hobbed, it would be unloaded to a loading station. This auto loading/unloading feature is very efficient for production but can also be disabled via software.
