CNC standing for Computer Numerical Control has been around now for over 50 years. Originally driven through stepper motors, then DC brushed and now AC brushless systems, they have evolved a long way. Current controls send digital signals to the drives, speeding up the processing of high speed data. Ajax can supply all these controls and advise you on the most suitable control for you, then we can train you how to use them. Ajax has been selling CNC machines for over 25 years.
