SAISC profile before each process and the great quality cuts and holes that the machine produces, the end result is a very cost effective combination 1 station machine that saves on space, stock holding and storage, EOT cranes and the like. So is it the answer to every fabricators needs? The answer is a simple no. It’s throughput per day would be substantially less than a 3 station combination mentioned above. Is it flexible in the types of profiles that can be cut? You bet! Any profile that fits into a 355 circle, whether hot rolled beams and columns, channels, flat bars, angles and hollow profiles that have steel thicknesses of less than 20mm. After careful market research into what their future customer’s needs could be and to what equipment was available in the market place, the TWTLP team chose a BLM LT 14 tube laser, which comes from Italy. Being an ex-Alfa Romeo (Alfetta GTV to be precise) driver, the author could not help but ask, was this state of the art Italian designed machine going to behave like an Alfa? (For those of you who have not driven an Alfa, if you are a perfectionist don’t ever try one.They are great concepts, they have magnificent mechanicals (whilst running), handling and braking, which is great as long as you don’t mind window winders falling off, the sun roof leaking, the boot latch not holding, rust, rust and more rust). The answer was a resounding no,“we have Italian design and structure but German brains” – all the controls are Siemens equipment with their reputation for reliability and precision. From a programming point of view, it’s ease of communication with 3D detailing packages including Tekla make the programming straight forward and not needing further draughtsman input. It has mind boggling accuracy and precision assisted by independent probes that take into account out of straightness and the like of input material. An absolute win-win for the right applications, and yes gents there are plenty applications out there. It is a state of the art staggeringly fast 2 axis machine that by clever detailing and programming does away with the need for complicated layouts or jigs to assist in assembling complicated jobs by means of tabs that fit into slots in exactly the right place. Another win-win for the downstream fabricator. What are the draw backs I hear you ask, perhaps the slowish set-up time is the only one I could detect. What a great afternoon visit I had to TWTLP, leaving me once again rueing my age that made me miss out on these great modern advances in steel fabrication. The second machine is a BLM LT Fiber tube laser.This machine can handle profiles that will fit into a 140mm diameter circle. For more details of the machines capabilities Metalworking News, January 2016 has an in depth article on the machines. Steel Construction Vol. 40 No. 1 2016 #
