MILLING & HOBBING
One machine for both process steps

If the task is processing materials that are difficult to
machine, such as those used for rotors in the oil and gas
industry, then precision milling is of the utmost importance. Here, high-quality surfaces and profile accuracy
are what counts.
Leistritz offers with its LWN 300 PM (Power Mill) a
solution for side milling and hobbing on one machine.
The milling cutters are arbor mounted to a Ø 50 mm
spindle with an outboard support by a counter bearing, to
achieve the high rigidity. This superior support produces
best surface finishes and a high tool life.
This insures rigidity while maintaining fast tool changeover times. Furthermore, the Power Mill
has a continuous diagonal hob shift, which utilizes the entire hob face during the cutting of a rotor to evenly
distribute tool wear. A complete rotor can be hobbed
without the frequent stops for measuring or the exchange of inserts.
