The benefits of all-electric tube bending machines for precision aerospace manufacturing applications are being highlighted by Unison (H1/B9). Unison machines feature a bending system based on precision digitally controlled servomotors. This all-electric architecture provides significant performance benefits in terms of rapid and repeatable software-based set-up, and lower energy consumption and noise, compared with traditional hydraulically powered machinery, says Scarborough, UK-based Unison.
Unison's laser-controlled spring-back correction system is available as a build-to-order option on machines for bending tubes from 50mm diameter upwards. The system automatically compensates for the natural tendency of metal tubes to spring back slightly after being bent, enabling parts manufacturers to implement a right-first-time production process.
"Aerospace is one of the most demanding applications for tube bending, and over time the manufacturing tolerances are tending to become even tighter," says Unison CEO Alan Pickering.
"Yet it's still commonplace to see older-style hydraulically actuated benders in use - machinery that is much more suited to large-batch production of run-of-the-mill components," he adds. "We are able to show that all-electric bending automation has helped aerospace manufacturers to evolve component production processes that are at the vanguard of what is technically possible in terms of precision, shape creation and cost effectiveness."
Visitors to the show can sign up for a tour demonstrating the productivity benefits of servomotor-controlled tube bending. Unison will take attendees to see how at least two UK users employ the high-precision technology - with a choice including applications at aerospace manufacturers.
