There are three main
operating modes provided by LBC technology: Productivity Mode, Quality Mode and Kerf Control Mode. In Productivity Mode, the cutting speeds achievable can be up to double that of a conventional 4kW solid-state laser. With aluminium, for example, the performance can be equivalent to that provided by an oscillator with 1.5 to 2x the laser power. This extra performance also provides significant cost reductions. If we take stainless steel processing as an example, the costs can be reduced by about 50 per cent of a conventional 4kW solid- state laser. Quality Mode has the
ability to provide dross free stainless steel processing up to 15mm, dramatically reducing secondary operations. Kerf Control Mode allows the cutting gap to be adjusted to suit the application. This ensures easier removal of parts from the cut sheet either by an automated part removal system or, in the case of thick parts, manually by the operator. The combination of LBC
technology, Vector Control technology and the 4kW single diode module fibre laser engine has allowed many users to increase their production
capabilities whilst reducing running costs. For example, Omnis Mechanical in the UK initially planned to purchase a 3kW fibre laser, but when seeing the Ventis capabilities for compressed air cutting, which are the same as a 6kW fibre laser, they decided the Ventis offered more benefits for their production. Germany’s Funke Werkzeugbau and AMS have both benefited from the high cutting speed and quality in aluminium, which was found to be superior to 6kW fibre lasers available on the market. In addition, Somis, of Italy, has been particularly impressed with the dross free cutting capabilities when processing stainless steel with Quality Mode. Finally, Spanish firm Model Metal commented that no other laser on the market (even those with much higher power) could achieve the same cutting quality in 25mm mild steel as the Ventis with LBC technology. Over 150 Ventis-AJ fiber
lasers have been sold into the European market since the machine’s official launch in late 2019. l
