Four th Unison bending machine ordered AIRCRAFT component manufacturer Globe Engineering has installed a fourth Unison all-electric CNC tube bending machine at its facility in Wichita, Kansas, USA. overlapping capacities, the Unison tube bending machines at Globe can bend tubes from 31.75 to 152.4mm (1.25" to 6") in diameter, with high levels of repeatability and accuracy.

aluminium, stainless steel and titanium tubes measuring up to 31.75mm (1.25") in diameter. Before investing in this latest machine, Globe had just one machine that was capable of bending stainless and titanium tubes from 5 / 8 " to 1" diameter. “We aren’t just creating new capability by buying a new Unison tube bending machine,” explained bend shop supervisor Shaun Knuth. “We’re creating capacity and a safety net, in case we have a breakdown.” Describing some of the key advantages that Unison all-electric tube benders have over hydraulic tube benders, he added, “They’re more efficient because they use less energy. In fact, they only use energy while they are in motion. By comparison, the hydraulic benders use electricity all the time they are running, with their energy usage increasing during cycle time. Electric machines are much quieter too. Our Unison all- electric tube benders also offer greater repeatability. You simply select the exact pressure you need; if you want 1,272 psi of pressure, you just type that in, and the machine creates exactly the same pressure every time.” Mr Knuth also praised the fact that Unison all-electric tube benders can be operated more slowly when hot- bending titanium, all the way down to a creep – a process that removes the risk of overheating and minimises scrap. He also pointed out that there is no need for titanium tubes to be lubricated with expensive, messy grease before hot bending when using all-electric machines. Mr Knuth said: “If there’s a problem we usually have a new part within a few days. The machines are so easy to use and we can install the parts ourselves.” Steve Haddrell, key account manager at Unison, added that Globe Engineering’s latest order is particularly rewarding. “Repeat orders are always great news because they carry a clear customer endorsement. In this case, the company decided that these attributes, combined with the build quality and reliability of Unison machines, significantly outweighed any short-term economic advantage of low-cost tube benders.”

In addition to supporting Globe’s ongoing requirements for bending high quality aircraft tubing, the new all-electric CNC tube bender from Unison will be used to bend a range of

Commissioned earlier this year, the new machine has joined Globe’s existing Unison all-electric tube benders at the Wichita site and will help to increase manufacturing capability. With
