Amada scores with Ventis fiber laser with LBC technology

Ventis-3015AJ is Amada’s first fiber laser cutting machine equipped with the specially developed LBC technology, which increases both processing quality and productivity. Combined with a newly developed 4 kW fiber laser module with excellent beam quality, LBC technology sets a new world standard for laser cutting according to the Japanese machine builder.

Technological advances

The German company Lang Gerätetechnik ordered the 100e Ventis in Europe with a double tower version of the Amada ASF-EU automation system. Long device technology is a general supplier of sheet metal. The company wanted to position itself even better in laser cutting and invested in technological advances.

Before deciding to buy a Ventis fiber laser, the company had the following requirements: Significant energy savings compared to CO2lasers, high processing speed and flexibility in material thickness and types (copper and brass). In particular, the price-performance ratio compared to 6 kW fiber lasers from other manufacturers and the versatility of production offered by LBC technology convinced Lang’s management. The cutting speed and quality were also impressive compared to higher power machines.

Flexible spray pattern adjustment

With conventional fiber laser cutting systems, the energy density decreases with increasing material thickness, which slows down the cutting process and results in a poorer cut. In contrast, the use of LBC technology allows flexible adjustment of the beam pattern to suit the application, while fully maintaining high efficiency and energy density.
To compensate for the loss of energy density in conventional fiber laser systems, higher output power sources must be used. However, this results in higher purchasing costs and higher power consumption.

In contrast, Ventis can reduce electricity costs by 30% with its specially developed 4 kW fiber laser with only one laser module and LBC technology. LBC technology has three main functions: productivity mode, quality mode and cut control mode.

Productivity mode

In productivity mode, the user can achieve a power improvement by cutting with nitrogen. When machining stainless steel, Ventis with LBC technology is twice as fast as a conventional 4 kW fiber laser cutting system and even 2-3 times faster with aluminum. These performance levels combined with lower energy consumption can reduce processing costs by up to 75%.

Quality condition

The quality condition can improve the surface roughness by about 50% compared to a traditional machine, while minimizing burr formation to less than 10 m. amada has shown that 15 mm stainless steel is burr-free after cutting. As a result, deburring can be omitted and processing costs reduced. Even in quality mode, it achieves a higher cutting speed than a traditional 4kW fiber laser cutting machine.

Locus Beam Control (LBC) technology makes it possible to work as productively with 4 kW as with a 6 kW fiber laser and at the same time improve the cutting quality.

Notch Control Mode

Finally, Notch Control mode enables process-reliable processing in automated system operation over an extended period of time. Depending on the thickness of the material, the width of the cut can be increased up to 2.3 times the usual width using LBC technology.

Large standard equipment

Ventis has a large standard range of delivery, including cutting with only one lens, an automatic 16-station nozzle changer, ‘Water Assisted Cutting System’ (WACS) for optimal cutting of thicker sheets, an X-conveyor and optimal accessibility both on the head and on the long side .

Ventis are available in sizes 3,000 × 1,500 and 4,000 × 2,000 mm and are equipped with an improved AMNC 3i Plus control. It has a self-diagnosis system and a rotary knob for easy feed adjustment, a cutting data library with up to 10 feed speeds per second. material, allowing time savings of up to 20%. Small, complex contours and angles are cut just as reliably as large geometries at maximum speed.

The Ventis 4 kW fiber laser processes 25 mm mild steel, 20 mm stainless steel, 18 mm aluminum, 10 mm brass and 8 mm copper.
