The SCHIESS RF 30 gear hobbing machine is a specialist machine for
machining large gear wheels. The machine is designed for machining of
gears by processing individual pitches of a gear wheel. The milling
machine processes a workpiece with diameter from 60 mm to 3500 mm and
a weight of up to 25 t. The spindle of the milling machine rotates at
a speed from 6 to 69 rpm.
The SCHIESS RF 30 machine is designed for milling with:
– cylindrical milling cutters in steel / cast iron up to module:
24/30
– disc milling cutters in steel / cast iron up to module: 33/42
– end mills in steel / cast iron up to module: 33/42 50/65
