LIEBHERR WSC 2000

Sąlyga: naudotas, Gamybos metai: 2007, Maximum gear diameter: 2000 mm Workpiece diameter: 2700 mm Table diameter: 1500 mm Maximum module: 22 Control system: 840D Rotational speed: 3.5 rpm Maximum table load: 20,000 kg Center distance: 70...1220 mm Kdedov E R Eispfx Adgew Stroke length: 30...330 mm Strokes per minute: 10...200 spm Total power requirement: 138 kW Machine weight approx.: 38 t Space requirement approx.: 11x5 m Machine: Full CNC machine with electronic hobbing synchronization for C and D axes and digital INDRAMAT drive technology. Self-rigid welded machine bed construction. Radial axis (X-axis) with hardened guideways, sliding guide with wrap-around, Longitudinal guide with recirculating roller shoes. Precision ground, preloaded ballscrew with backlash-free preloaded nut. Digital AC drive technology with backlash-free gearbox. Linear measurement system for radial positioning. Free-standing machine table with electrohydraulically backlash-free preloaded twin worm gear, segment gear diameter 1365 mm, hydrostatic axial and radial bearings, automatic workpiece weight compensation. Table bore diameter 500 mm continuous, open at the bottom. Water-cooled digital AC servo motors. The machine must be installed on a foundation. Column: Machine column as highly rigid cast construction for 1200 mm axial travel. Axial axis (Z-axis) with hardened guideways, sliding guide, longitudinal guide and wrap-around with recirculating roller shoes. Precision ground ballscrew with backlash-free preloaded nut. Digital AC drive technology. Encoder for axial positioning. Shaping Head: SK 4.1 with hydraulic NC servo drive for shaping spindle movement and gear cutting wheel lift-off, stroke length 330 mm, shaping spindle diameter 160 mm. Hydrostatically mounted shaping spindle, straight and side guidance of the lift-off. Maximum tool diameter: 300 mm. Drive motor power: 30 kW Number of strokes: 10 - 200 spm, stroking speed: 5 - 45 m/min. Shaping spindle speed for working and return stroke can be programmed independently. Spindle speed is constant in the cutting area. Maximum gear cutting wheel speed: 10 rpm, digital AC drive technology. Gear cutting wheel lift-off direction can be manually reversed for internal and external gear cutting. Shaping spindle axis can be manually adjusted up to 50 mm off machine center to avoid return stroke collision of the gear cutting wheel.
