The superb Aciera F1 Universal Precision Milling Machine - shown with the plain table mounted.
The F1 was the smallest of the Aciera Universal Miller range. All the table and head movements could be by screw or lever feed and the machine, together with its wide range of accessories, was designed to enable the small workshop to cope with as wide a variety of super-precision work as possible. Machines to some point in the 1980s used 3-step flat-belt drive from the motor whilst later models employed a narrow (5 mm) 4-step V-belt. The drive on both types also passed through an integral 2-speed gearbox that gave a very useful range of speeds from 125 to 4000 r.p.m.
