Design features

Cutting speeds

The characteristics of the fiber source and the optical chain developed by Salvagnini, comprising the fiber that transports the beam and the focusing head, generate a laser beam with a high power density for high-speed cutting (more than 60 m/min) on medium and thin material and high-quality cutting on thicker sheets.

Running costs (per hour)

The L3 boasts extremely low running costs that are provided thanks to:

  • The high performance of the source and chiller
  • The elimination of an optical path
  • The elimination of laser gas
  • Low maintenance costs
  • The option for cutting with compressed air

EtherCAT protocol

The Six numeric controller is equipped with a high-speed communication system EtherCAT as such is required to ensure the desired performance at high cutting speeds provided by the fiber laser sources. The numerical controller controls the axis movement, the position of the focused laser beam, the laser source parameters and the use of auxiliary gases providing constant and accurate process synchronization.

High-quality cutting with a single optic

The L3 system features a focusing head developed entirely in-house by Salvagnini that is exalting all the previous experience of the company and is tended to improve the features and dynamics offered by optical fiber transmission. The head features a single optic for high-quality cutting across the entire range of thicknesses, assuring fast production changeovers and slashing retooling times.


Laser TRADJUST is a revolutionary series of proprietary functions incorporated into the CNC of Salvagnini SiX controller. This series of functions flawlessly combines the requirements of the application to the cutting process with the trajectories generated by CAMLaser. TRADJUST automatically, and transparently for convenience of the operator, calculates the modulation of cutting parameters as a function of changes in direction, speed and instantaneous acceleration. Accordingly, with a single, predetermined cutting parameter for every material and thickness, regardless of the cutting profile, the L3 system could not be simpler to use.

A wide range of machinable materials

Thanks to the wavelength typical of fiber, the L3 system can:

  • Effectively cut even highly reflective materials, such as high purity aluminum alloys, brass and copper, the metals that are extremely difficult to process on traditional CO2 systems;
  • Provide high cutting speeds and combine that with high quality cutting of coated materials such as zinc-coated and galvanized steel.

Exclusive automation solutions 

Due to the wide range of available devices for material transportation, S4Xe can work in the unmanned production mode and can be easily integrated into flexible manufacturing systems AJS or FMS. Various loading and unloading devices allow optimization of the production flow by eliminating unnecessary operations and the associated costs and providing at the same time high quality and guaranteeing fast return on investments. With all these characteristics, the Salvagnini systems can adapt perfectly to the different requirements of production and, according to the process development in the manufacturing enterprise of the customer, can be used both as stand-alone units and as integrated parts of automated manufacturing facility systems.

SRP optical centering sensor

The L3 System can be equipped with an optical centering sensor (SRP), which allows:

  • Quicker positioning of the blank to be processed.
  • Implementation of the centering required for post-processing operations in cases when processed parts have been previously subjected to other operations (punching, caulking or deep-drawing).
  • SRP is completely integrated with CAMFiber and can be programmed in the "one click” mode.

Software suites

Salvagnini offers a complete suite of software for management of its laser systems. The many modules that compose the management suite are subdivided into three areas, and assure ease of use, productivity and process integration.

Every Salvagnini laser system comes completely equipped with a suite of software packages (JOB.CONSOLE) that allows the operator to manage the system in a simple and intuitive way. Particular attention has been placed on the management of diagnostics (EASYDATA) and on maintenance (MAINTENANCE MANAGER). The on-board programming suite can be augmented by the simulation package (SIMFiber) and by nesting software to be programmed directly on the machine (NestFiberLight).

The METALSTUDIO platform’s CAD/CAM+NEST software packages and the simulation and time-cost and production cost analysis packages make these machines highly competitive and allow their owners responding effectively to the changing needs of the market.

The OPS applications allow the integration of Salvagnini systems with a company’s MRP/ERP system. These custom packages provide a customer increased control, streamlined processes, and a substantial reduction of costs, through the elimination of errors and low value activities.

The electronic source: low consumption, zero maintenance.

Compared to a traditional CO2 laser source, the fiber source provides energy savings of more than 70% and a reduction of running costs by more than 50%. Practically eliminated, near zero, is the energy consumption during warm up and standby; the energy consumption of the entire system (machine, 3 kW resonator, chiller and connections) during stand-by is always less than 5 kW.

Energy consumption (kilowatt hour)

Compared to a traditional CO2 laser source, the fiber source provides energy savings of more than 70% and a reduction of running costs by more than 50%. Practically eliminated, near zero, is the energy consumption during warm up and standby; the energy consumption of the entire system (machine, 3 kW resonator, chiller and connections) during stand-by is always less than 5 kW.

Total safety

Salvagnini’s fiber laser systems are CLASS 1 machines. The machine comes equipped with all the necessary protection to assure absolute safety in compliance with current standards. The laser cutting device is completely enclosed from all sides and equipped with a protective cap. In addition, the large observation windows are approved for solid state laser use. The source is equipped with advanced beam reflection control systems on three levels to ensure beam integrity and operational safety. The optic fiber has a diameter of 50 mkm which allows using very thin laser beams that way maximally reducing the risks.

Advantages and features of the Salvagnini fiber laser cutting systems:

  • The system maintenance costs can be reduced up to 50%, due to the simple structure of the laser source and the elimination of the optical path and laser gas.
  • Energy savings of more than 70% for the entire system (machine, 3 kW resonator, chiller and connections).
  • Higher cutting speeds and faster burning due to the high density beam.
  • Single focusing head for all materials and thicknesses.
  • A wider range of materials for machining.
  • Cutting of stainless steel with a protective film in one pass.
  • Simple and compact design, thanks to the reduced dimensions of the source and chiller and the use of fiber for transmitting radiation, which simplifies the structure of the machine.
  • Elimination of warm-up time and the respective power consumption.
  • A wide range of possibilities provided by the standard software.
  • A wide range of optional software for the simulation of the cutting process and optimized nesting; time and cost estimating for the manufacturing process; remote controlling and reporting.
  • High environmental friendliness of the system.
