Self-rigid machine bed in welded construction. Radial axis (X-axis) with hardened guideways, sliding guide with wraparound design, Longitudinal guide with circulating roller shoes. Precision-ground, preloaded ball screw with backlash-free preloaded nut. Digital AC drive technology with backlash-free gearbox. Linear measurement system for radial positioning. Free-standing machine table with electrohydraulic, backlash-free, preloaded double worm gear drive, division gear diameter 1,365 mm, hydrostatic axial and radial bearings, automatic workpiece weight compensation. Kodpfx Afov E R Eiodedw Table bore diameter 500 mm, continuous, open at bottom. Water-cooled digital AC servo motors. The machine must be installed on a foundation. Column: Machine column as a high-rigidity cast construction for axial travel of 1,200 mm. Axial axis (Z-axis) with hardened guideways, sliding guided, longitudinal guide and wraparound with circulating roller shoes. Precision-ground ball screw with backlash-free preloaded nut. Digital AC drive technology. Rotary encoder for axial positioning. Gear shaping head: SK 4.1 with hydraulic NC servo drive for shaping spindle movement and cutter lifting, stroke length 330 mm, shaping spindle diameter 160 mm. Hydrostatically mounted shaping spindle, straight guiding and side guiding of cutter lifting. Maximum tool diameter: 300 mm. Drive motor power: 30 kW Stroke rates from 10 – 200 SPM, stroke speed from 5 – 45 m/min. Shaping spindle speed for working and return stroke can be programmed independently. In the cutting area, the spindle speed is constant. Maximum cutter head rotational speed: 10 rpm, digital AC drive technology. Cutter lifting direction for internal and external gears manually reversible. Maximum lateral offset of the shaping spindle axis by 50 mm from machine centre to avoid return stroke collision of the cutter head, adjustable manually.
