Self-rigid machine bed in welded construction. Radial axis (X-axis) with hardened guideways, sliding guide with overhang, Longitudinal guide with recirculating roller shoes. Ground, preloaded ball screw with backlash-free preloaded nut. Digital AC drive technology with backlash-free gearbox. Linear measurement system for radial positioning. Freestanding machine table with electrohydraulically backlash-free preloaded double worm gear, pitch circle diameter 1,365 mm, hydrostatic axial and radial bearings, automatic workpiece weight compensation. Through-table bore diameter 500 mm, open downward. Water-cooled digital AC servo motors. The machine must be installed on a foundation. Column: Machine column as high-rigidity cast construction for axial travel 1,200 mm. Axial axis (Z-axis) with hardened guideways, slide-guided, longitudinal guide and overhang with recirculating roller shoes. Ground ball screw with backlash-free preloaded nut. Digital AC drive technology. Encoder for axial positioning. Gear Shaping Head: SK 4.1 with hydraulic NC servo drive for stroking spindle movement and cutter lift-off, stroke length 330 mm, stroking spindle diameter 160 mm. Hydrostatically mounted stroking spindle, straight guide, and lateral guide for cutter lift-off. Maximum tool diameter: 300 mm. Drive motor power: 30 kW Ksdpjv E R Eiefx Aabend Stroke rates from 10 – 200 spm, stroke speed from 5 – 45 m/min. Stroking spindle speed for cutting and return stroke can be independently programmed. Spindle speed is constant in the cutting area. Maximum cutter head rotational speed: 10 rpm, digital AC drive technology. Cutter lift direction manually reversible for internal and external gearing. Lateral offset of the stroking spindle axis by up to 50 mm from machine center manually adjustable to avoid collision of cutter during return stroke.
