The LC series is a machine system for the machining of spur and helical gears
and cylindrical gear shafts and helical gears and cylindrical gear shafts,
which is characterised by its special performance and versatility.
Compared to other gear manufacturing processes, gear hobbing is characterised
by its characterised by its high consistency of machining results over the
entire tool life.
