CNC External Cylindrical Grinding Machine

Studer S31 CNC

Condition: used, Year of construction: 2007, control Siemens Sinumerik 840 D weight 57.000 kg voltage 400 V Gleason PFAUTER CNC gear hobbing machine P 2400/2800 for gear cutting of cylindrical and worm gears as well as all other regularly occurring rollable profiles and shapes on the cylindrical workpiece circumference. Large gear hobbing machines from Gleason offer maximum productivity for roughing and finishing cylindrical gears for many industries: wind turbines, industrial gearboxes, mining and shipbuilding, gear machining and many more. The power range of the drive takes future tool developments into account. Of course, the gear hobbing head drive is also backlash-free. These machines are particularly well suited for use with state-of-the-art, cutting materials, regardless of whether dry or wet machining is preferred. The machine can be used for dry or wet machining and is also equipped with the appropriate chip conveyor for both machining methods. The machine is equipped with an internal profile milling head as a motorised milling head. --> Working range and technical data Nominal workpiece diameter: 2.400 mm --> Largest millable diameter approx.: 2.800 mm --> Smallest/largest distance between cutter and workpiece axis: 100/1.200 mm --> Largest axial slide travel (special design): 1.300 mm --> Largest clampable cutter (internal milling head): --> Diameter max: 440 mm Iaodpfx Aswzyp Iegdjp --> Max. cutter width: 90 mm --> Swivel range of the internal profile milling head/vertical axis: +/- 15° --> Milling mandrel taper: HSK-B160 --> Maximum milling cutter travel: 300 mm --> Table diameter: 2.500 mm --> Part wheel diameter: 2.200 mm --> Table bore --> Diameter: 800 mm --> Depth: 875 mm --> Maximum table load approx.: 40.000 kg --> Max. feed and rapid traverse speeds: --> axial (Z-axis): 4.000 mm/min --> radial (X-axis): 3.000 mm/min --> tangential (Y-axis): 3.000 mm/min --> Milling cutter cooling lubrication device/electric centrifugal pump: approx. 150 l/min --> Increased drop height of magnetic chip conveyor: 1,600 mm --> Increased main stand: 1,300 mm axial slide travel --> Internal profile milling head as motor milling head instead of standard motor milling head --> Max. millable profile depth in steel with approx. 600 N/mm² strength: approx. 65 mm --> Infinitely variable milling speed: 50 - 150 min?¹ --> Max. milling cutter diameter: 440 mm --> Min. milling cutter base circle diameter: 310 mm --> Max. milling cutter width: 90 mm --> Min. internal diameter at 0° bevel angle: 800 mm+) --> Max. workpiece height at 0° bevel angle: 600 mm --> Max. workpiece ring thickness (including clamping device): 500 mm
