METHOD FOR MACHINING WORKPIECES IN A LATHE AND CONTROL UNIT FOR SAID LATHE

摘要

Method and apparatus for the machining of workpieces in a lathe, which lathe comprises two spindles, the centre lines of which lie in each other's extensions and which are each, on mutually opposed faces, provided with a chuck for the clamping of a workpiece, of which spindles at least one can be displaced in the direction of the centre lines relative to the other spindle, and a tool-holder, which can be displaced in the directions perpendicular to and parallel to said centre lines, for at least one toolpiece for the machining of a workpiece clamped into one of the chucks, which method comprises the steps of (1) the clamping of a first workpiece in the chuck of one of the two spindles, (2) the clamping of a second workpiece, identical to the first, in the chuck of the other of the two spindles, in such a way that the faces of the workpieces to be machined are directed towards one another, (3) the provision of a respective toolpiece in the tool-holder for the machining of the first and the second workpiece, and (4) the effecting of a suitable simultaneous displacement of the at least one moveable spindle and the tool-holder relative to the other spindle for the execution of a simultaneous machining of two identical workpieces clamped in the chucks.
