Large diameter part e.g. Kaplan turbine rotor, machining device, has control unit to allow coordinated functioning of drive and motor units, and assembly for machining of external peripheral and inner regions of part

摘要

The device has a mobile carriage (12) in translation along a guiding channel that extends for permitting the carriage to be displaced on a platform (4). A mobile or telescopic arm (14) is supported by the carriage and associated to a motor unit that is driven by a control unit (25). A machining unit has a machining tool adapted on the arm and driven by the control unit. The control unit allows a coordinated functioning of a rotational drive unit, the motor unit, and a machining assembly for machining of an external peripheral region and an inner region of a part to be machined e.g. rotor.
