Machine with excellent accuracy and high versatility in producing: External gears Internal gears Herringbone gears Double helical gears Gear racks.The outstanding economy of the MAAG SH 450 derives from the high metal removal rate (for materialuntil 1400 N/mm2 and 400 HB) and simplicity of form and long tool life of theroughing cutter, which keeps the tooling costs extremely low. After the roughingoperation, the gear teeth are finished machined in the same set-up by thegenerating method. And that makes it in most of all cases possible, to avoidgrinding. With the full swivel cutter ram, any desired helix angle can be set.The finishing generating operation yields a very good tooth accuracy in shortmachining time. The machining cycles for the plunge cut and the generatingoperations take place automatically. The vertical working range is so large thateven double-helical gears can usually be completely machined without alteringthe set-up. The cutter ram is driven by a DC reversible motor via a 7-startspindle. Helical gears or double helical gears with a small run-out groove couldbe cut by a helical rack shaped cutter. When using the swiveling cutter holderfor cutting gears with great helix angles the ram stroke could be highlyreduced.
