One of the most desirable small milling machines, the Aciera F1 is popular with horologists and other micro mechanics. Employing the Schaublin W12 collet in the spindle as well as the Schaublin 70 spindle nose for the dividing head the F1 is an excellent companion to the Schaublin 70 lathe. The F1 came equipped with both screw and lever operated slides increasing the machines versatility. Sensitivity of the vertical slide was ensured by the use of an adjustable spring compensator located in the body of the machine. Earlier machines had a six speed spindle from a three speed flat belt drive and two speed gearbox while later machines produced eight speeds from a pair of four stepped V belt driven pulleys combined with the gearbox. A vast range of accessories were available for these machines allowing a wide range of machining jobs to be performed. Probably the most desirable accessories include the beautiful spigot mounted machine vice and the indispensable direct indexing head which could be converted to full dividing head with the addition of a very rarely seen worm and wheel gearbox equipped with three interchangeable indexing plates. Some equipment from the very similar Sixis 101 will also fit this machine. An updated version of the F1 is currently made by a firm in Switzerland, but I have been unable to identify the manufacturer. If any reader can provide any information on these machines I would be very grateful. |
