Amada recently launched its ENSIS-6225AJ fibre laser cutting machine into the European market. With the ability to process a 6.2m x 2.5m sheet of material, the new machine is available in 6, 9 and 12kW variants, with all powers able to cut up to 25mm mild steel, stainless steel and aluminium.
Many new and proven Amada technologies are utilised to provide the highest levels of cutting performance to keep customers at the competitive edge.
Being able to process larger sheets, or multiple sheets in a large cutting area, leads to several benefits. More efficient material utilisation and higher production flexibility. Previously, Amada’s Ensis fibre lasers were available in 3m by 1.5m and 4m by 2m variants. Now, the series has been expanded to incorporate 6.2m by 2.5m capabilities.
Utilising Amada’s proven Variable Beam Control technology, first released in 2014, the Ensis-6225AJ automatically adapts the laser beam mode (not just the focal position and spot size) to each material and thickness combination.
This technology also allows the beam mode to be changed between the pierce and the cut, to provide a high-power density beam shape for high speed piercing, then instantly changing to the ideal beam shape to provide high speed, high quality cutting. It also means that a single lens can be used to process all materials and thicknesses.
Several new Laser Integration System features have also been added to the Ensis-6225AJ, as first released on the Regius-AJ, full linear drive laser in 2020. These provide more autonomous functionality, rather than relying on the operator to carry out certain checks.
The i-Nozzle Checker automatically checks the nozzle condition and changes it in conjunction with the standard 16 station nozzle changer if damage is detected, thereby removing any subjective operator decision. This system also incorporates automatic laser beam to nozzle alignment, significantly reducing start-up times and processing issues.
The i-Process Monitoring system constantly monitors the cutting and piercing processes and takes remedial action if required, in order to keep the machine producing parts. The cutting lens protection glass is monitored by the i-Optics Sensor, which alerts the operator if the protection glass needs to be replaced, to avoid potential stoppages.
Several other Amada technologies are also supplied as standard on the Ensis-6225AJ. Firstly, Amada’s original Water Assisted Cutting System (WACS), used for processing thick mild steel, has been upgraded to allow two different levels of assistance, depending on the part geometry.
