Self-rigid machine bed of welded construction. Radial axis (X-axis) with hardened guideways, sliding guide with wrap-around design, Longitudinal guide with roller recirculating shoes. Precision-ground, preloaded ball screw with backlash-free preloaded nut. Digital AC drive technology featuring backlash-free transmission. Linear measuring system for radial positioning. Free-standing machine table with electrohydraulically backlash-free preloaded double worm gear, index wheel diameter 1365 mm, hydrostatic axial and radial bearings, automatic workpiece weight compensation. Through table bore diameter 500 mm, open at the bottom. Water-cooled digital AC servo motors. Machine must be installed on a foundation. Column: Machine column as high-rigidity cast construction for 1200 mm axial travel. Axial axis (Z-axis) with hardened guideways, sliding guide, longitudinal guide, and wrap-around roller recirculating shoes. Precision-ground ball screw with backlash-free preloaded nut. Digital AC drive technology. Rotary encoder for axial positioning. Knedpfx Ajv E R Eiec Ned 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. Within the cutting area, the spindle speed remains constant. Cutter wheel speed max. 10 rpm, digital AC drive technology. Cutter relieving direction for internal and external gear cutting can be manually reversed. Lateral offset of the shaping spindle axis up to max. 50 mm off machine center, manually adjustable, to prevent cutter wheel collision during return stroke.
