Abstract:
1. A method for machining by lathing at least two elongate workpieces ( 16 ) having a longitudinal axis, comprising: chucking said at least two workpieces ( 16 ) in a rotating fixture ( 15 ) and rotating the at least two workpieces at a machining speed about an axis of rotation ( 29 ), feeding a turning tool ( 18 ) which performs the lathing transversely with respect to the axis of rotation ( 29 ), with a cutting speed of lathing resulting from the rotation of the workpieces ( 16 ) in relation to the turning tool ( 18 ), the workpieces ( 16 ) are chucked with their longitudinal axes parallel to the axis of rotation ( 29 ), but eccentrically and at a radial distance from the axis of rotation ( 29 ), in the fixture ( 15 ), with the axis of rotation ( 29 ) not passing through the workpieces ( 16 ), and the turning tool ( 18 ) is fed radially from outside transversely with respect to the axis of rotation ( 29 ), the workpieces ( 16 ) orbiting about the axis of rotation ( 29 ) on an imaginary cylinder for forming a non-round profile, and an orbiting speed corresponds to the rotational speed of the workpieces, and, during an orbiting movement about the central axis of rotation ( 29 ), the workpieces execute a revolution, and always a same respective outer face of the respective workpieces ( 16 ) points radially outward during lathing, while the workpieces ( 16 ) are then held immovable in relation to the fixture ( 15 ), wherein the at least two workpieces ( 16 ) are lathed in a common operation.
