Abstract

A turning machine which is used preferably for machining spatially complicated shapes. In order to achieve further machining possibilities, apart from the known adjusting possibilities and machining possibilities by means of a universal rest, the spindle head, alternatively or in addition hereto, is mounted on a machine bed in a longitudinally displaceable manner, if necessary in a transversely displaceable manner, an in a swivelable or rotatable manner.

A universal turning machine comprising:

a multi-track bed having first tracks and second tracks disposed substantially side-by-side with said first tracks, said multi-track bed comprising a spindle head machine bed having said first tracks thereon, said first tracks extending in a longitudinal direction in a bed plane;
a spindle head having means for mounting a workpiece thereon, including a headstock means and a receiver means, rotatively mounted to said headstock means, for rotatively supporting a workpiece for rotation about a receiver axis, and having a center axis perpendicular to said bed plane, said spindle head being mounted on said first tracks for movement thereon in said longitudinal direction;
indexing control means for controlling the angle of said receiver means about said receiver axis;
an auxiliary machine bed having said second tracks thereon;
a rest for mounting thereon working means which work the workpiece on said spindle head during rotation of the workpiece by said receiver means, said rest being mounted on said second tracks for movement therealong in opposite first directions, said spindle head machine bed and said spindle head therewith being pivotable in said bed plane about at least a swivel axis for adjusting the relative positions of the working means and the workpiece prior to working the workpiece with the working means, said swivel axis being perpendicular to said bed plane and parallel to and spaced from said center axis, said spindle head on said first tracks and said rest on said second tracks being movable past each other respectively in said longitudinal and first directions;
and
means for supporting said rest on said second tracks such that said rest is movable in second directions transverse to said first directions, said first and second directions being parallel to said bed plane;
said spindle head being moveable on said first tracks and in pivotal movement with said spindle head machine bed in said bed plane about said swivel axis and said rest being movable in said first and second directions, all during rotation of the workpiece by said receiver means with the working means engaging the workpiece so as to work the workpiece, said spindle head being movable on said first tracks to a position where said swivel axis is spaced from said center axis a distance between approximately 100 cm and approximately 300 cm.
