ACUT

L3 is natively set up for cutting with nitrogen and oxygen. The ACUT option extends the possibilities of the L3 and allows cutting with compressed air, if suitably treated. Productivity is similar to cutting with nitrogen, but with much lower costs.

FACE

Intelligent design, intuitive and easy-to-use: FACE is the Salvagnini human-machine interface for the whole product range. 

Industry 4.0

Digital transformation and Industry 4.0 are key topics for staying competitive on the market. When adopted, they can implement and manage complex, integrated, highly automated high-performance systems, and can help to develop simple solutions that require no structural changes to the production layout, making the world of smart manufacturing much more accessible.

  • ANC

    The automatic nozzle changer, with nozzle-holder magazine, increases the autonomy of the L3 in unmanned production.

  • APC2

    The adaptive process sensor monitors the piercing in real time, for greater speed and higher quality. It also checks for any cutting losses, and in the event of a fault, stops the process and resumes it with suitably remodulated parameters. It is also used to automatically search for the focal length.

  • AQM/APM

    These are turnkey devices that are complementary to ACUT and connect directly to the factory pneumatic supply or to a compressor upstream of the system. AQM filters the air, while APM ensures the pressure values required for the cutting process.

  • SVS

    Artificial vision application that acquires the image of a sheet metal leftover positioned on the worktable and transforms it into a dxf to be used as the starting format for a new nest. 

  • NVS

    Artificial vision application that checks the centering of the laser beam and the state of the nozzle. Thanks to the machine learning algorithms, this option can suggest solutions that help to reduce waste.

  • AVS

    Artificial vision application that speeds up the centering of the metal sheet and allows previous machining operations to be used as references for positioning it, with no restriction on shape.

In the laser world, automation is playing an increasingly key role: on the one hand, cutting speeds risk turning loading and unloading into bottlenecks, and on the other hand, automation can help to reduce the impact of labor costs. The loading/unloading and sorting connections satisfy all automation requirements: from stand-alone operation, to integration in flexible cells or in automatic lights-out factories.

  • CPE

    The CPE pallet changer for manual loading-unloading is used for rapid pallet exchange; the raw material always enters above the outgoing cut sheet.

  • ADB

    The ADB connection automatically picks the sheet up from a pack in masked time.

  • ADLU & ADLL

    The ADLU and ADLL devices automate the loading of the sheet metal and the unloading of the cut sheets, with very rapid cycle times; they also eliminate the intermediate handling that is usually done by the operator, and they are designed for integration with the MCU.

  • LTWS & LTWS Compact

    The LTWS and LTWS Compact store-towers are designed for unmanned loading, unloading and storage of materials; they are compact in size and have extremely short cycle times, up to 50 seconds.

  • MV

    The MV tray-store with picker-crane allows unmanned operation, offering high autonomy in the management of sheet metal and semi-finished or finished parts.

  • TN

    The TN manual sorting device helps operators to separate the cut parts from the skeleton, allowing cutting and sorting to proceed in parallel.

  • MCU

    The MCU automatic sorting device is used to easily stack parts of different shapes, sizes and weights. MCU drastically reduces the waiting times between the end of cutting and the start of the next production step.

Intelligent system, constant quality

Practically everything you ever wanted to know about the L3 fiber laser, satisfactorily explained.

Productivity
Versatility
Automation

The productivity of a laser is affected by market factors, i.e. everything the system cannot control, such as batch size, frequency of production changes and mix of materials/thicknesses; and by technological factors, which are linked to the features of the cutting system, such as source power, level of automation and digitalization.

The field of application, with its specific mix of materials, thicknesses and production strategies, is the key factor in the choice of technology: versatile and transversal, as in the case of the L3, or with high dynamics, like the L5.

Increasingly small batch sizes need rapid automation for rapid or masked-time production changes. Salvagnini offers a wide range of solutions: high-performance systems that are modular and compact for managing increased output, as well as systems that are open to downstream processes and designed to be effectively integrated into the factory’s production flow.

The range of thicknesses and the cutting performance depend on the power of the source. To meet different production needs, Salvagnini has introduced two sources: 6kW high-density and 10kW.

Efficiency and productivity are achieved by eliminating downtime, optimizing the process and simplifying the control system: these objectives can be reached with digital solutions that support the operator’s work and the OPS process software that manages the exchange of information with the ERP in real time and balances the production flow.

Increasing the productivity of a laser means guaranteeing efficiency throughout the whole process. The Salvagnini formula blends the power of the source with intelligent sensors and solutions integrated into the L3 laser, automation upstream and downstream of the cutting process, and digitalization. The result? Higher performance, and an optimized production process. 

The L3 is equipped with a single laser head, designed by Salvagnini, used to cut all the allowed materials and thicknesses. It is equipped with the patented DRY-COOLING system, used to actively control the temperature of the optics. Its process sensors control and adapt the piercing in real time, monitoring any cutting losses, stopping the process, and restarting it with appropriately corrected parameters. The TRADJUST function, integrated into the proprietary control, ensures automatic parameter modulation according to the trajectories, making the system easier to use.

The market demands cutting-edge systems, with high performance, that are automated yet easy to use, manage and maintain. The L3 is an agile laser: the proprietary functions, the multitask human-machine interface and the artificial vision systems help operators to effortlessly solve the problems in their day-to-day work. Salvagnini software solutions effectively connect the laser to the factory ERP and other technologies downstream, guaranteeing the traceability of the parts, supporting the operator in sorting the parts and providing progress feedback in real time to the production manager, whether this is human or virtual.

The artificial vision systems implemented on the L3 simplify activities which require time or generate errors and waste. They are simple solutions that increase the flexibility of the system and broaden its field of application. AVS turns laser cutting into a work station downstream of punching, thus guaranteeing the maximum precision of the cut parts. SVS regains scrap and sheet metal leftovers, responding to urgent needs or replacing any waste in downstream machining activities. NVS checks that the laser beam is centered, and uses the machine learning algorithms to monitor the state of the nozzle and reduce waste.

It is the perfect combination: digitalization has led to the development of simple solutions, which have turned several traditional processes into smart production flows. OPS, the modular software for production management, receives the production list from the factory ERP/MRP in real time and supports the programming activities, defining priorities, rules and algorithms. OPS therefore helps to automate the process, adding intelligence to the system. The OPS applications for simplifying workshop management include PDD, which supports the operator via the monitor for manual part separation and sorting, and LPG, which laser-guides the operator in the pick-up sequence.

These challenges relate in particular to the recovery of autonomy and efficiency. Automating loading/unloading/sorting operations ensures improved cutting system performance and brings benefits to the whole production manufacturing chain. Implementing simple, quick office software reduces the risk of turning programming into the bottleneck of production. Integrating ERP/MRP and process software for managing production automates the distribution of information, helping to create a lean, error-proof production environment.

Automation plays an increasingly important role: the highest performing laser systems require loading/unloading/sorting devices that are equally high-performing. These solutions not only guarantee greater efficiency and autonomy for the systems they serve, they also reduce the impact of labor costs and the return-on-investment time.

The data from LINKS, the Salvagnini IoT solution, shows that the efficiency of a standalone laser system generally does not exceed 60%. This parameter varies with configuration: systems with automation have average efficiency values that are much higher, reaching 80% for horizontal loading/unloading solutions and even 90% if we consider the LTWS store-tower.

The minimum level of automation for the L3 laser is the CPE device, the ultra-rapid electrical pallet changer. The raw material always passes above the material that has already been cut, preventing any scrap from previous machining being deposited on the sheet metal.

The LTWS store-tower has automated loading/unloading, an enabling factor for increasing the autonomy of the cutting system. It ensures different materials and thicknesses are available for just-in-time production, reducing waiting times for sheet metal sourcing, and operator dependency. In contexts marked by low volumes and rapid production changes, LTWS is a winning choice.

The LTWS store-tower offers even greater performance when equipped with a sorting device: the automatic MCU or the manual TN. The store-tower manages different materials, thicknesses and sizes, reducing waiting times and making loading/unloading extremely fast: just 50 seconds. STORE, the store control software, is able to identify the loading trays, once emptied, as trays on which to stack the cut material, thus increasing operational autonomy. 

Software

Industry has changed: flexibility and efficiency are fundamental requirements for managing increasingly smaller batches or rapid item turnover rate.  And developments in technology have in some way upset the balance between workloads, with increasingly fast systems which however need to be guided by more and more specific machine programs, the generation of which is increasingly time-consuming. This is why software is increasingly crucial to improving the efficiency of machinery.

STREAM is Salvagnini’s answer to the modern industrial context, a programming suite that improves reactivity and reduces costs, operating errors and process inefficiencies.

OPS is the Salvagnini modular production management software which optimizes the entire production process, exchanging real-time information between the machinery and the factory ERP/MRP.

Salvagnini’s IoT solution, increases the global efficiency of the laser system. LINKS allows real-time monitoring of the machine’s performance and independent analysis.
