The F1P could also be had with a variable-speed motor which, as the machine retained its 4-step belt drive as well, gave ranges on each pulley setting of: 100 to 500 rpm, 200 to 1000 rpm, 400 to 2000 rpm and 800 to 4000 rpm.  When fitted with a 60 rather than 50-cycle motor spindle speeds were generally some 25% faster

Sold in large numbers to schools and colleges throughout Europe, the Emco F1 CNC was the first low-cost CNC milling machine to filter down into private hands. Surprisingly effective, many are still in use today. The power-feed 420 x 125 mm table had rapids with a longitudinal travel of 200 mm, across of 100 mm and vertically 200 mm. Infinitely variable spindle speeds ran from 300 to 2000 rpm.
