The model YNH3120 is a gear hobbing machine designed for cutting
spur gears, helical gears and worm wheels. When a chain wheel hob
is used, the machine is capable of cutting chain wheels. The perfectly designed machine is high in rigidity, consistent in
working accuracy and easy to set up & maintain. The gears can
be cut either by the conventional hobbing method or by the climb
hobbing method. The machine is therefore well-suited for job-lot or
batch production of gears in the machine-building enterprises.
