Put in on the firm’s Gloucester facility, which has AS9100 rev D and Nadcap AC7116/3 Rev B approval in place for each spark and wire erosion, the arrival of the Sodick ALC600G wire EDM and AG60L die-sink EDM will underpin numerous essential contracts throughout each the civil and army aerospace markets.

Established in 1978, Excel Precision Group operates from two fashionable amenities in Gloucester and Leeds, which collectively home over 30 CNC wire and spark erosion machines. This capability, together with its accreditations, make Excel one of many main EDM subcontract operations within the UK, with explicit emphasis on aerospace and defence.

“Few EDM subcontractors have each AS9100 and Nadcap approval,” acknowledged Steve Batt, operations director on the Gloucester facility. “This stage of course of management permits us to serve an intensive variety of aerospace and defence prospects.”

Together with the necessity to change older machines, a part of the rationale behind the corporate’s funding in Sodick expertise was as a result of imminent ramp-up of an present defence contract that’s at the moment scheduled to run till 2022.

“We checked out each Sodick and our present provider of EDM machines, however the check cuts offered by Sodi-Tech EDM had been merely higher,” mentioned Batt. “Particularly, the floor end produced by the AG60L spark eroder actually caught our consideration. Because of the presence of particles, some machines battle to copy the floor end achieved on the edges of components, on the underside face. Nevertheless, this proved no such subject for the AG60L.”

Excel Precision’s AG60L has been set to work producing a wide range of aerospace components, together with stainless-steel actuator elements. In whole, the aerospace sector instructions about 40% of the machine’s time. The opposite Sodick machine, the ALC600G wire EDM, has round 50% of its output despatched to aerospace prospects, together with the titanium defence half.

“In contrast with our previous machines and course of, utilizing the ALC600G has remodeled our operation for this element,” mentioned Batt. “For a begin, we beforehand wanted two machines, whereas now the half is accomplished in its entirety on the ALC600G. Additionally, our previous machine would solely obtain a 90% cross fee on an angled face with a 5µm tolerance. With the Sodick machine, the cross fee is 100%. That step-up in high quality makes an actual distinction on excessive value-added components resembling these.”

Excel Precision is at the moment tasked with producing 200 of the titanium defence components each month, though this determine will shortly rise to 600. Utilizing the ALC600G, the corporate can produce round 24 per day. Nevertheless, with work for different sectors, each Sodick machines run for twenty-four hours a day, 4 days per week, with lengthy cycle-time jobs loaded on the weekends.

“We’ve not had Sodick machines at Excel since earlier than 1995, however we’re very happy to make the change again,” added Batt. “The expertise has moved on significantly and we can’t fault the machines or the staff at Sodi-Tech EDM, who’ve been very supportive since set up in early 2019.”

Excel Precision really started life in Leeds, however began the Gloucester operation seven years in the past by acquisition. The machines at Gloucester had been round 20 years previous and the corporate has since been progressing its manner by a gradual substitute programme.

“One factor we’ve seen is the compact nature of the Sodick machines,” acknowledged Batt. “We had been in a position to match each Sodicks into the area beforehand taken up by one older EDM. Additionally, whereas we didn’t purchase the machines for pace, it’s troublesome to not discover the positive aspects we’ve achieved. The titanium defence half beforehand had a cycle time of 65 minutes, but it surely’s accomplished in simply 35 minutes on the ALC600G wire EDM, a 46% enchancment. As for the AG60L die-sink machine, the outcomes we get, notably on deep cavities, is like nothing we’ve seen earlier than. Now we have additionally lowered our electrode consumption dramatically; we are able to now full many roles utilizing only one electrode.”

Good progress over the previous two years has seen Excel Precision Group hit an annual turnover of £2 million, and extra progress is predicted transferring forwards.

“There are a lot of elements that set us aside from opponents, not least the capability we provide and the accreditations we maintain,” concluded Batt. “As well as, we consider the extent of labor and repair we offer is second-to-none. It’s all about high quality, on-time supply and buyer communications, all backed up by investing within the newest applied sciences.”
