One modular machine concept for the heavy-duty machining of All hobbing techniques and form mil-ling by using the single indexing method. spur and helical gears crowned and tapered gears Dry or wet machining with advancedHSS or carbide tools. worm gears cluster gears Skiving/finish hobbing of hardenedgears. special profiles (e.g.compressor rotors) Milling of internal gears (option for S 1200-2000). non-circular gears herringbone gears (double helical gears) Shaping of external and internalgears. internal gears Chamfering and deburring usingCNC spindle (optional). Integrated gear inspection (optional)....

The modular machine concept hasbeen consistently applied even to thelarge machines of the S series, guaran- teeing an outstanding cost-benefit ratio and low maintenance costs. Grey cast-iron machine bed formaximum static and dynamic rigiditywith integrated fluid circulation for thermal stability. Motorized hob head in compactdesign with tangential slide and back-lash-free gear train. > Work table drive with hydraulically-compensated double worm gear drive,high-resolution AC digital drive as the position-controlled follow-up axis (electronic gearbox). Linear slides with backlash-free preloaded...
