The work-pieces are jet engine turbine disks, with diameters up to 45″. Heights range from just a few inches to a foot tall. The materials are proprietary high-temperature superalloys. Machining operations entail multiple early-stage rough processes. Generally, the work-pieces are either held in a three-jaw chuck or custom fixture.
This installation utilizes eight (8) MVL-12HD machines. Momentum, in fact, developed the MVL-12HD for this application, and it features a super rigid 240mm (9.44″) square ram and class-leading 45/55kW (60/74HP) spindle motor. These machines were configured to include three-jaw power chucks and hydraulic cylinders. Chuck and cylinder packages may be added to late model Momentum 1.2-meter table size machines such as the MVL-12, the MVL-12HD, and the MVL-12M easily, without spindle or other major changes. (Lead-time may be paced by the availability of the customer’s preferred chuck type and brand).
The MVL’s produce parts at least 30% faster then did the various VTL brands employed before them. And the eight (8) machines installed in this application have provided well more than 100,000 hours of operation with better than 99% uptime availability.
‘We run them hard. Nothing but high-temperature alloy forgings, and they have run 24 hours a day, six days a week! Our first purchase was two units in early 2012. They are the original blue Momentum colors. Then, two more in late 2012. Then, in mid-2013 we bought two more units, and we added numbers seven and eight in 2016. These machines are all heavy-duty and rigid, and we get great surface finishes, even on those tough materials.’
