for aluminumfor stainless steelfor copper

Overview
Designed to improve ergonomics and simplicity of use and guarantee maximum precision and repeatability of processes, the L3.G4 eliminates activities with low added value and optimizes consumption, ensuring lower costs per piece. It is a versatile fiber laser cutting machine with a high-accessibility gantry architecture and proprietary control functions that make it agile and easy to use.

Key selling points

• Highly-accessible gantry architecture guaranteeing full accessibility to the working range, rigidity and precision.
• Single optic laser head developed by Salvagnini, equipped with DRY-COOLING for active temperature control of the optics.
• Proprietary TRADJUST function for automatic modulation of cutting parameters according to trajectories (simplifies use by employing a single cutting parameter).
• Adaptive process sensors (APC2) monitor piercing and cutting in real time, detect cutting losses and automatically remodulate parameters.
• Standard and PowerCut cutting functions to select the most suitable operating mode for either safety/unmanned manufacturing or increased reactivity and speed.
• Artificial vision applications and part tracking/identification to increase flexibility, simplify handling and reduce errors.

Product overview — process improvements

• Automation: storage and automatic loading/unloading/sorting devices increase system autonomy and eliminate bottlenecks; reduce labor cost impact.
• Simple to use: intuitive FACE HMI, multi-task interface, TRADJUST, artificial vision and part tracking make the L3.G4 accessible to operators and reduce intervention time.
• Process efficiency: evolved sensors, rigid structure and integrated software reduce downtime, minimize errors and lower consumption per piece.

Automation & Solutions

• CPE pallet changer for rapid manual pallet exchange (raw material enters above outgoing cut sheet).
• ADB automatic pick-up from packs in masked time; ADC/ADLU/ADLL automate loading/unloading with very short cycle times and integration with MCU sorting.
• LTWS and LTWS Compact store-towers for unmanned loading/unloading and storage with cycle times up to about 50 seconds.
• MCU automatic sorting for stacking parts of different shapes, sizes and weights, drastically reducing waiting times.
• TN manual sorting devices to separate cut parts from skeleton in parallel with cutting operations.

Software & Digitalization

• FACE: human-machine interface, simple and intuitive across product range.
• STREAM: programming suite that improves material efficiency and reduces programming time and errors.
• OPS: modular production management software that synchronizes machine activity with factory ERP/MRP and manages priorities, rules and production lists.
• LINKS: Salvagnini IoT solution for real-time monitoring of machine performance and data-driven analysis to optimize production flows.

Features & Options

• Single laser head with DRY-COOLING and advanced process sensors.
• Cutting with nitrogen, oxygen and ACUT option for cutting with treated compressed air (up to 20 mm in ACUT configuration), with APM2 device for required pressure management.
• TRADJUST automatic trajectory-based parameter modulation.
• Optional automatic nozzle changer (ANC) and automatic focal search features.
