Abstract
A numerically controlled turning machine comprises a main spindle (H.sub.s) and at least two cross slides (K.sub.1,K.sub.2) each provided with a saddle (W.sub.1 and W.sub.2, respectively). Another saddle (W.sub.3) is provided at the main spindle end. The cross slide (K.sub.1) is provided in addition with a driven tail spindle (G.sub.s). The control of the machine is subdivided into a first control system which includes X-axis and Z-axis controls as well as C-axis control with positional adjustment and a second control system which does not have any C-axis control but does include X-axis and Z-axis controls.
Claims10
A numerically controlled lathe comprising a main spindle, at least two cross slides opposite said main spindle, the first cross slide being provided with a driven tail spindle and a first saddle, the second cross slide being provided with a second saddle, a third cross slide at the main spindle end, and a first control system including X-axis control, Z-axis control, and C-axis control with positional adjustment, the C-axis control for selectively controlling one of said main spindle and said tail spindle, such that a workpiece supported by the main spindle may be machined simultaneously with two tools which are supported by said first and second saddles whereby said C-axis control is applicable to the main spindle and that a workpiece supported by the tail spindle may be machined with a tool supported by the third saddle under control of said first cross slide whereby said C-axis control is applicable to said tail spindle.
The lathe as claimed in cleim 2 or 3 wherein, in the "double spindle operating mode", the third saddle is controllable by the first control system as to its X and Z axes, and the second saddle is controllable by the second control system as to its X and Z axes.
