The FANUC company is a world leader in the development of computer numerically controlled (CNC) machine tools and in robotics. It introduced the first computer-based control system in 1975 although the founder of the company, Dr. Seiuemon Inaba, had been studying and developing hard-wired NC machines at the Fujitsu company since 1952.

The development of machine tools which could cut and shape metal parts automatically, and with repeatable accuracy, received a big boost during the Cold War. These machines were much quicker and more accurate compared to those controlled by human machinists. It was also believed, particularly in the USA, that such tools would allow the rapid dispersal of arms production to alternative sites in the event of a nuclear attack. Large amounts of money were committed to research in this area but the systems produced were expensive and found few customers outside the aerospace and defence industries.

FANUC reversed this trend and pioneered the development of control systems that were suitable for a wide range of engineering companies. Today CNC machines are indispensable for the production of almost all industrial products. This FANUC 6-TB numerical control system is fitted to a Colchester 2000L CNC lathe showing a typical application for the equipment.
