The Aciera F1 is considered by some to be the perfect partner for the Schaublin 70 lathe in the watchmaker’s workshop. Rightly so in my opinion: it takes the same W12 collets as the Schaublin 70, has the same thread on the nose of the indexing spindle and can easily be set up for either precision vertical milling or wheel cutting.
I have just got hold of a nice example of one, albeit in need of a clean. It came with a few accessories including a vertical support (the same spindle is used in both horizontal and vertical modes, requiring a bracket for vertical mode) and the indexing spindle. This F1 will sit alongside the Schaublin 70 and, hopefully, will soon have an electronic indexing attachment fitted to the indexing spindle.
