Abstract
The invention relates to a lathe and grinder apparatus for turning and/or grinding works and for any like machining thereof requiring spindles to be used, which comprises two dual-spindle units (T1, T2), that may be even more than two in number, arranged in a side by side parallel relation, and interfaced by means of manipulators (R1, R2, R.sub.3), which are for feeding works to the first dual-spindle unit, for delivering the machined works from the final dual-spindle unit, and for transferring the workpieces, may be in a modified direction thereof, from a dual-spindle unit to the successive one, so as to allow the various work surfaces to be machined.
Claims4
A lathe and grinder apparatus for machining a workpiece, said apparatus comprising:
- at least first and second dual-spindle units arranged side-by-side and each including a pair of spindles and a spindle carrier device having a longitudinal axis and a tool-carrying slide, the longitudinal axes of the spindle carrier devices being arranged in a mutually parallel relation, the said dual-spindle units being equipped with means which, in timed relation, causes the said spindle carrier devices to be indexed by 180.degree., whereby one spindle of each of the pairs of spindles is brought in turn into cooperation with a respective one of the tool-carrying slides of the said dual-spindle units, and the other spindle of each of the pairs of spindles is moved into a station for a workpiece to be fed and delivered,
- at least one manipulator for each dual-spindle unit, which is caused, in use, to swing about a respective pivot axis extending parallel to the longitudinal axis of the associated dual-spindle carrier device, each said manipulator being each axially shiftable on the pivot axis thereof, and being each fitted with two gripping means for gripping a workpiece, and for acting on inoperative spindles that are not cooperating with the tool-carrying slides so as to deliver a workpiece from the inoperative spindle of the first dual-spindle unit and so as to fit into this spindle a new workpiece taken from a feeding station, and so as to deliver a machined workpiece from the inoperative spindle of the second dual spindle unit, and so as to fit into this spindle a partly machined workpiece supplied from the first dual-spindle unit.
