Heavyweight machining on a Millturn from WFL

In this TECtalks episode from Austrian machine tool manufacturer WFL, application engineer Manfred Baumgartner discusses exactly what's required to machine a 60 ton component such as parts for gas, steam and wind turbines, rollers and crankshafts. 

WFL Millturn machines can process components up to 60 tons in weight, 14m in length and diameters up to 2m. Even better, because all machining and measurement operations can be conducted on a single Millturn and heavy components can be processed with just a few clamping operations, optimum efficiency is guaranteed.

Large, heavy componets have a tendency to sag because of the extreme weight. In fact, the sag of a 60 ton turbine shaft is so great, it needs to be taken into account when clamping the workpiece. This variable can then be compensated for via the correct design of the clamping device and appropriate clamping method.

FEM calculations can be used to precisely determine how the workpiece can be correctly clamped and supported. WFL uses either a rolling or hydrostatic steady rest to achieve these objectives. 

In the UK, WFL machines are sold and supported by Kyal Machine Tools.
