Laser Cutting Heads

Piranha's PlateLASER systems feature shop-serviceable reflective cutting heads with specialty ground copper mirrors instead of traditional collimating and focusing lenses. Built-in temperature sensors integrate with the CNC control to prevent damage, and the sealed design allows onsite maintenance rather than costly off-site repairs. This design reduces downtime and service costs compared to competitor heads requiring factory returns for lens replacement or calibration.

Piranha's 12kW fiber laser cutting head can pierce 1-inch thick steel plate in approximately 2 seconds and 3/4-inch plate in roughly 0.8 seconds—recognized as the world's fastest controlled-pierce cycle. This rapid piercing dramatically increases throughput in heavy plate applications compared to 6kW systems, reducing cycle times and boosting production efficiency for high-volume fabrication shops.

Yes, especially with Piranha's shop-hardened, serviceable cutting head design. The reflective head architecture allows mirror inspection, cleaning, and replacement onsite by trained technicians without returning the entire assembly to the factory. This field serviceability minimizes downtime and keeps your laser operational. Contact Piranha's technical support team at 800-338-5471 for guidance on maintenance intervals and replacement parts availability.

A 12kW fiber laser cutting head can cut steel plate up to 1 inch thick and beyond depending on assist gas and speed requirements. With nitrogen assist gas, Piranha's system cleanly cuts steel up to 5/8 inch thick without oxide edge, eliminating secondary finishing operations. For thicker materials or oxygen-assist cutting, the head can process plate over 1 inch while maintaining high edge quality and cut speed.

Routine maintenance includes daily inspection of the protective window for spatter or contamination, weekly cleaning of gas nozzles and optics (mirrors or lenses), and periodic calibration of capacitive height sensors. Piranha's reflective cutting heads simplify maintenance with copper mirrors that are more durable than lenses and easier to clean. Built-in temperature sensors alert operators to potential issues before damage occurs, and the CNC control monitors head status continuously for preventive alerts.

Most industrial laser cutting heads, including Piranha's reflective design, support nitrogen, oxygen, and compressed air as assist gases. Nitrogen produces oxide-free edges on stainless steel and aluminum, oxygen accelerates cutting of mild steel with an exothermic reaction, and compressed air offers a cost-effective option for thinner materials. The cutting head's gas delivery system and nozzle design must match the gas type and pressure requirements for optimal cut quality and pierce performance.
