The SKE 120 shaping head with dynamic rotary drive and movable head slide occupies less space at a stroke length of 120 mm, increasing stroke position travel range to 650 mm (Platform 2) and 350 mm (Platform 3). The optional NC swivel column slide, which produces conical gear teeth at a shaping spindle angle between -1 and +12 degrees, has been optimized to achieve greater rigidity. If NC swivel column slides are not used, the shaping spindle angle can be adjusted by as much as ±0.45 degrees using a cam.
