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 quite a lot of vital contracts throughout each the civil and navy aerospace markets.

Established in 1978, Excel Precision Group operates from two trendy services 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 degree of course of management permits us to serve an intensive variety of aerospace and defence prospects.”

Together with the necessity to substitute older machines, a part of the explanation behind the corporate’s funding in Sodick expertise was as a result of imminent ramp-up of an present defence contract that’s presently 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,” stated 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 duplicate the floor end achieved on the edges of components, on the underside face. Nevertheless, this proved no such situation for the AG60L.”

Excel Precision’s AG60L has been set to work producing quite a lot of aerospace components, together with chrome steel actuator parts. 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“In contrast with our outdated machines and course of, utilizing the ALC600G has remodeled our operation for this part,” stated Batt. “For a begin, we beforehand wanted two machines, whereas now the half is accomplished in its entirety on the ALC600G. Additionally, our outdated machine would solely obtain a 90% move charge on an angled face with a 5µm tolerance. With the Sodick machine, the move charge is 100%. That step-up in high quality makes an actual distinction on excessive value-added components comparable to these.”

Excel Precision is presently 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 swap 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 truly started life in Leeds, however began the Gloucester operation seven years in the past by means of acquisition. The machines at Gloucester had been round 20 years outdated and the corporate has since been progressing its approach by means of a gradual alternative programme.

“One factor we’ve observed is the compact nature of the Sodick machines,” acknowledged Batt. “We had been in a position to match each Sodicks into the house beforehand taken up by one older EDM. Additionally, whereas we didn’t purchase the machines for pace, it’s troublesome to not discover the features 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, significantly on deep cavities, is like nothing we’ve seen earlier than. We have now additionally decreased our electrode consumption dramatically; we will now full many roles utilizing only one electrode.”

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

“There are lots of elements that set us other than opponents, not least the capability we provide and the accreditations we maintain,” concluded Batt. “As well as, we imagine 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.”
