FANUC CNC Series 31i-LB / 31iPB - Features and Benefits

Available on the world‘s best-in-class machine tools


Available on the world’s leading performance machine tools including punch presses, laser cutting machines, multi-axis lathes, 5-axis machining centers, gear cutting machines, transfer machines and state-of-the-art, non-traditional applications.

High-speed machining for quality and reduced cycle times


Advanced software algorithms analyze part geometries and machine capabilities and adjust trajectories and feed rates to provide the smoothest laser cutting paths for the highest processing speed at the specified precision.

Simple operation for maximum productivity


Operators with previous FANUC experience can use their existing skills as they learn new techniques, and existing part programs will run smoothly without modification.

Connectivity for today’s high-tech manufacturing


The 100-MBit Ethernet interface integrates the CNC into a network for high-speed part program transfers and the collection of process related data. It also supports remote troubleshooting from the maintenance department or a machine tool builder anywhere around the world. Because the Ethernet port does not use a public operating system, it is practically “hacker-free” and virus immune.

High reliability and easy maintenance


Reliable hardware with clear diagnostics provides a stable platform for maximum machine availability. With a mean-time-between-failure of 32-years, and a lifetime replacement part availability and support commitment*, FANUC controls provide machine availability that far exceeds any competitor.

Powerful simulation tools


Simulation of CNC operation, part programming and maintenance screens for effective training of operators, part programmers, maintenance engineers and technicians in a safe environment.

State-of-the-art hardware


Ultra-high-speed processors provide fast interpolation times with up to 1000-block look-ahead, controlling up to 24 axes simultaneously. Up to 5 independent, 9.1 nanosecond-per-step PMC ladders execute simultaneously, supporting up to 4096 digital inputs and outputs.

Customer specific solutions


Unique solutions may be realized using powerful programming languages, user interface development tools, real-time macros and PC functionality. Series 30i/31i CNCs may connect with Windows compatible PCs, or rugged, diskless Windows CE.NET operator interfaces.
