Gear shaping head:
SK 4.1 with hydraulic NC servo drive for shaping spindle movement
and cutter relieving, stroke length 330 mm, shaping spindle diameter 160 mm.
Hydrostatically mounted shaping spindle, straight guiding and lateral guiding for relieving motion.
Maximum tool diameter: 300 mm.
Drive motor power: 30 kW
Stroke numbers from 10 – 200 strokes/min, stroke speed from 5 – 45 m/min.
Shaping spindle speeds for working and return stroke can be programmed independently.
