MAX Photonics opened in 2004 with its international headquarters in Shenzhen, China. More information is available at MAX Photonics.

Raycus was established in 2007 and is headquartered in Wuhan, Ching. In March 2013, it developed China’s first 10kW industry-level fiber LASER, making China the second country to master the core technologies of 10,000W fiber LASER in the world. More information can be found at Raycus.

IPG Photonics was founded in 1991. In 2000, IPG invested in new high-capacity production facilities in the United States to manufacture its own LASER diode pumps, a major component of its fiber LASERs and amplifiers. More information can be found at IPG Photonics.

nLIGHT was founded in 2000 in Vancouver, WS to focus on high-power semi-conductor LASERs. More information can be found at nLIGHT.

nLIGHT Corona fiber LASERs give users the ability to tune the beam settings based on their application. With a single fiber LASER, users can rapidly select from high-intensity, small-spot-size beams to large, donut-shaped beams, and everything in between. This dramatic advance allows optimal thick and thin metal cutting, higher cutting speed, superior quality, and improved piercing and small-feature processing with a single tool. End users get the best of all worlds—the speed of high-power fiber LASERs for thin metal processing, the quality of CO2 LASERs for thick metal processing, and the high uptime and lower operating costs of a fiber LASER solution.

  • 3kW to 15kW – Deliver excellent productivity for advanced cutting and welding applications.
  • Optimized Tuning of Beam Size and Shape – Maintains fiber LASER performance, stability, efficiency, and reliability with spot sizes from 100µm to 300µm and beam shapes from top-hat to donut mode.
  • Rapid Beam Switching – Beam adjustments in less than 30ms allows for real-time optimization of each process step while maintaining full power operation to maximize productivity.
  • Back-Reflection Protection – Hardware-based back-reflection protection allows processing of even the most reflective metals with no interruptions or damage to the LASER.
  • Breakthrough Integrated Beam Shaping – Removal of free-space optics, zoom process heads, and external fiber-to-fiber couplers avoids complex performance-limiting hardware.
  • Unparalleled Serviceability – Modular design simplifies repairs and maximizes uptime.


Piranha FLEX LASERs integrate different cutting head designs which are matched to the requirements and performance of the selected resonator make and power.

Piranha cutting heads are implemented in collaboration with our manufacturing partners in China. LaserMech cutting heads are provided from their facility in Michigan.

Oxygen (O2) and nitrogen (N2) are the most common assist gases used when cutting metals with a fiber LASER. Air is a combination of both O2 (21%) and N2 (78%), small amounts of argon and carbon dioxide, and trace amounts of other gases and water vapor.

Air cutting provides many of the benefits of N2 cutting along with increased cutting speeds in thicknesses 10ga (0.135”) and thinner and significantly lower cutting gas costs.

Air used in LASER cutting must be available with the correct purity, dryness, pressure, and flow. Typical shop air compressor systems are unable to deliver the air quality and performance necessary. A dedicated air compressor system is required.

Nitrogen generator is the separation of air components to capture nitrogen. Nitrogen makes up 78% of the gas in the atmosphere. The rest is 20.9% oxygen, 0.9% argon, 0.03% carbon dioxide and trace gases such as hydrogen, helium, neon, krypton, and xenon. For industrial LASER cutting equipment, PRESSURE SWING ABSORPTION (PSA) is used to provide the high pressures and flow rates required.

Nitrogen Generation Systems

NOTE: The maximum flow rate and purity required depend upon the cutting application and edge quality expectations. Other nitrogen generation systems are available to meet different requirements. Please contact Piranha for more information.

Consumable kits are available which provide a starting stock of items that are recommended for a range of LASER cutting applications. If a different combination of items is desired, please contact the sales department for a quotation specific to those items.


The Remote CNC Control Station is located at the rear of the LASER enclosure and includes dual monitors and a keyboard. The main CNC control screen and video feed is mirrored. This system allows for LASER operation when loading or unloading the pallets.


The pop-up ball transfer sheet loading assist system is designed to allow material to be easily moved to the material reference stops. Ball transfers will raise to a location above the pallet slats. Once the operator locates the work piece against the stops, the ball transfers will retract so that the work piece rests directly on the slats, in the correct zero location. The system is located below the outside pallet and will work with either pallet in the pallet load location. This system is available for 510 and 613 configurations. Consult with your Piranha sales representative if another size is requested.


Piranha recommends preparing an optics servicing area located away from manufacturing area. This area must have minimum air movement and a dust free environment. For best results, we recommend purchase of a laminar flow box located in an office area.

NOTE: Optics contamination is the leading cause of premature cutting head failure. It is important that optics, such as cover slides, are changed in an extremely clean environment. This area will also be used for on-site cutting head maintenance (to be done by our technicians).


CNC Programming of the Piranha FLEX requires CAM software capable of supporting the advanced functions of the machine. The customer is responsible for all costs associated with the development of any new post processor from their selected CAM  software vendor. Piranha will provide any information required for the post processor development and will verify that the NC code samples created by that post processor are functional. Requests for information and NC code samples for testing must be
received by Piranha eight (8) weeks prior to the scheduled machine shipment.

If extra start-up time is required by Piranha to work with the CAM provider and to test the NC code during or after the machine installation, the additional Piranha service time and expenses will be invoiced to the customer at Piranha’s standard service rates.



The Piranha FLEX must be in an area which has the following ambient conditions:

  1. Ambient temperature between 10° and 40°C [50° and 104°F]
  2. Relative Humidity at 95% or less

NOTE: Piranha requires that the LASER and chiller always remain on to avoid costly damage from condensation.  


No special foundation is needed for the Piranha FLEX LASER. Standard concrete floors of a minimum 150mm (6”) depth are recommended. Flatness should be within 12mm (0.5”). There should be no expansion joints, saw cuts, or cracks in the floor beneath the frame of the LASER.

NOTE: Customer shall install and utilize bulk liquid oxygen and bulk liquid nitrogen storage tanks. Using portable tanks for O2 or N2 will create additional chances of contamination entering the gas supply lines and the cutting head due to frequent tank changes. Cont0.amination will cause cutting head lens failure and thus cause machine down time and additional operating expense.
