Description: 

The machine is Like  new and will be delivered with a precision chart, ensuring cutting quality DIN 7.

The main characteristics of the machine include excellent accuracy and high versatility in producing external gears, internal gears, herringbone gears, double helical gears, and gear racks. The MAAG SH 250/300  offers outstanding economy due to its high metal removal rate (for material up to 1400 N/mm2 and 400 HB) and the simplicity of form and long tool life of the roughing cutter, which keeps tooling costs extremely low.

After the roughing operation, gear teeth are finished machined in the same setup by the generating method, often avoiding the need for grinding. With the full swivel cutter ram, any desired helix angle can be set, allowing for very good tooth accuracy in short machining time during the finishing generating operation. Machining cycles for the plunge cut and generating operations occur automatically.

The machine's vertical working range is large enough to usually allow complete machining of double-helical gears without altering the setup. The cutter ram is driven by a DC reversible motor via a 7-start spindle.

Equipped with a swivelling cutter holder DS-250, the machine can cut helical gears or double helical gears with a small run-out groove. When using the swivelling cutter holder for cutting gears with great helix angles, the ram stroke could be highly reduced.
