Nottingham, UK-based CNC profiling specialist, Lasershape, has installed a new Trumpf TruLaser 5030 fibre CNC laser cutting centre with BrightLine technology and LiftMaster automated load/unload. The system is one of the first of its type in the UK.
Trumpf claims its BrightLine technology achieves excellent quality when cutting thick sheets with a fibre laser, which conventionally is best suited to thin sheet cutting. Using BrightLine, it is possible to change from thin to thick sheet processing on a single machine platform without any loss of quality, the company says. Up to 25mm thick steel, stainless steel and aluminium can now be cut using a solid-state laser with excellent edge quality.
‘We already have two Trumpf 5030 fibre machines with 3kW resonators and two Trumpf CO2 models – the addition of the new machine with 5kW resonator and BrightLine fibre technology will create vital additional capacity,’ said Lasershape director, Tim Leam. ‘Importantly, because it is capable of processing both thin and thick sheets, it will create extra capacity on both our existing fibre and CO2 machines.’
BrightLine is a technology that enables vast beam diameter adjustability, a capability that conventional fibre lasers have lacked. Larger beam diameters that provide wider kerfs are required to process thicker materials more effectively and with greater stability. A wider kerf also makes it easier to remove parts from the material skeleton, while other advantages include the ability to cut smaller contours, and the absence of spatter when piercing.
In the early months of 2014, the existing laser profiling machines at Lasershape were at full capacity despite the company operating 24 hours a day, seven days a week. As a consequence, the decision was taken to introduce a new machine, this time with automation.
‘It’s our first Trumpf with a LiftMaster system and the thinking is to pursue bigger contract, longer running jobs,’ said Leam. ‘The new TruLaser 5030 fibre with LiftMaster can change a sheet, including parts, in 50 seconds. This is a great advantage on jobs for sectors such as shopfitting, where batch sizes for brackets can be 10,000 or more.’
