FANUC CO2 Laser Cutting Systems

For those laser cutting applications where CO2 is, and will continue to be, a more appropriate laser processing technology, FANUC continues to offer RF-excited fast axial flow CO2 laser oscillators in five power ratings, 1KW through 6KW. Complimented by high-fidelity power control, high-frequency pulsing and precise axis/laser-synchronization of the 30i/31i-LB Plus CNC, FANUC CO2 Lasers deliver maximum performance over a wide range of processing applications and material types - from high-speed sheet metal fly-cutting to high-power cutting of steel plate up to 32mm (1¼-inches) thick.

The FANUC 30i/31i-LB Plus Laser CNC supports many CO2-specific laser technology requirements, like servo-driven Optical Path Length Control, used to maintain an optimal laser beam length between the oscillator and the cutting head. FANUC now applies the CO2 Laser communications across its proprietary, noise-immune CNC optical bus FSSB (FANUC Servo Serial Bus) – controlling the servo velocity-loop at rates of up to 31.25 µs and offering performance gains that are essential for true high-speed laser fly-cutting.


Laser Cutting Machines - Cutting & Material Types



When it comes to bevelling, CO2 is more accurate than plasma cutting and faster than milling. A good CO2 machine will allow you to bevel edges of up to 40 mm - the perfect solution for cutting steel plate.


Oxide-free Cutting

CO2 lasers cut clean without leaving oxide residue on the workpiece. This makes using a C02 machine a great alternative to milling on stainless steel parts requiring an excellent finish. Given extra productivity resulting from its speed, it makes sense to seek advice on the pros and cons of laser cutting as an alternative to milling.


Intricate Shapes and Tiny Grooves

CO2 machines make it possible to cut intricate shapes and tiny grooves down to a fraction of a millimeter.



Laser cutting is ideally suited to cutting wood and plastics. It leaves beautifully edges, cuts plywood, and can be used to punch paper and cardboard. A method that is both versatile and cost effective, laser cutting makes a great solution for suppliers to the media and advertising industries.

Advantages of Using FANUC CNCs in Laser Cutting Machines


Dedicated CNCs for Laser Machines

Efficient Servos, Less Costs

With the constant accelerating and decelerating moving from hole to hole, laser machines use lots of energy. FANUC’s efficient servo drive systems can reduce the servo energy consumption by as much as 50 percent.


Better Quality Thick & Thin Parts

Look-ahead functions automatically adjusts laser power and axis feedrates to cut high quality sharp corners, which can be challenging in thick material. Accurately adjusting both the laser power level and pulse frequency reduces thermal load and provides uniform and clean edge quality in rounded corners, especially valuable in thin materials.


Safer and Faster Operations

FANUC’s tracing (Gap Control) function ensures that the distance between the laser cutting nozzle and workpiece surface is kept constant. The CNC is in total control of the Z-axis position, which allows for improved safety, higher processing speeds and programmable nozzle clearances.

Tight Synchronization of Laser Output and Axis Positioning

FANUC CNC laser commands are processed on the same high-speed fiber optic bus as the axis position loop updates. This ensure extremely tight synchronization between laser power and axis positioning, an essential component for raster type laser etching.

Better Finishes & Laser Marking

Laser pulse frequencies in excess of 32kHz improve cutting-edge quality and decreases dross, more than halving standard cutting edge roughness in thin materials. The minute laser output control provides ultra-stable laser output at low power levels providing superior quality laser marking capabilities.

More Reliable Processing

On CO2 Lasers machines, FANUC’s patented servo driven “trombone” mirror control ensures that the laser beam length is kept constant from the resonator to the cutting head for more reliable processing, even on a large moving-beam laser machine.

Robot Laser Interface Function

FANUC's new Laser interface functions combines the industry leading software users interface with high speed control hardware that optimizes the laser output based on the robot positioning. Integrated functions for 32kHz pulse control and robot speed based ramping controls the power output through pulse modulation or constant wave providing excellent processing performance and quality for cutting and welding applications.
