Schaublin 125, 135, 150 and 160 Lathes. Schaublin 125   The 125, 135, 150 and 160 lathes were all massively constructed, well designed machines. All models have infinitely variable spindle speeds and the 125 also features independently driven variable carriage feeds. The 135, 150 and160 lathes featured ball-screw lead screws. On these machines the lead screw always remains stationary (with the exception of those fitted with rapids, where the leadscrew is rotated during rapid traverse) while the ball-nut is rotated to give sliding traverses (including manual movement by handwheel) and screwcutting. The 125 was available three versions: version A as a turning machine only; version B as a turning and screwcutting machine using change wheels; and version C with full universal screwcutting gearbox. These machines were very expensive when new and consequently are quite rare (especially the 160). Machines in excellent condition still command good prices, however, potential purchasers of such machines should be aware all models are quite complicated and that worn machines are extremely expensive to recondition.
