Fanuc is the most widely used CNC control in the world, and its G-code dialect is the de facto industry baseline. That ubiquity is its biggest advantage: programmers, operators and service are everywhere, spare parts are available, and machines are easy to integrate — all of which supports strong resale value.
Fanuc spans generations from the classic 0/16/18/21 series to the modern 0i and 30i/31i/32i controls, which add high-speed look-ahead, nano interpolation and 5-axis features. When valuing a Fanuc machine, the control generation and installed options (rigid tapping, high-speed machining, probing) matter as much as the iron.
