Description

The machine is practically new and will be delivered with a precision chart. Cutting quality DIN 7!

The main characteristics of the machine are excellent accuracy and high versatility in producing external gears, internal
gears, herringbone gears, double helical gears and gear racks. The outstanding economy of the MAAG SH 250/300 S
derives from the high metal removal rate (for material until 1400 N/mm2 and 400 HB) and simplicity of form and long tool life
of the roughing cutter, which keeps the tooling costs extremely low. After the roughing operation, the gear teeth are finished
machined in the same set-up by the generating method. And that makes it in most of all cases possible, to avoid grinding.
With the full swivel cutter ram, any desired helix angle can be set. The finishing generating operation yields a very good tooth
accuracy in short machining time. The machining cycles for the plunge cut and the generating operations take place
automatically. The vertical working range is so large that even double-helical gears can usually be completely machined
without altering the set-up. The cutter ram is driven by a DC reversible motor via a 7-start spindle.
The machine is equipped with a swivelling cutter holder DS-250. Helical gears or double helical gears with a small run-out
groove could be cut by a helical rack shaped cutter. When using the swivelling cutter holder for cutting gears with great helix
angles the ram stroke could be highly reduced.
