Extra Capability Reduced Costs and Won New Work Away from US Supplier

The purchase of a high specification Tornos Deco 20a, installed in April at AEL (Dorset) Limited of Blandford Forum, has not only taken a huge cost out of the business by considerably reducing AEL's subcontract base, but has won significant volumes of work away from a US supplier. The company has grown tenfold in its first two years of business.

Until recently, AEL were using two turning and two machining centres backed up by a network of subcontractors to service the aerospace, electronics, medical and defence sectors. AEL director David Ross says: "Our work just kept growing and although our XYZ fixed head turning and machining centres were capable of producing the majority of our work, we had no capability for the smaller, more complex, volume parts." Investment in the Deco 20a has enabled the company to offer its customers the appropriate capacity and capability.

Another major customer had been having difficulty finding a UK supplier that could meet the high quality and lead times required on a range of critical parts. After many attempts, they settled into a pattern of buying large quantities at long lead times from the US. David continues:

"Having seen our Deco and the history we had with them on smaller volume parts, they agreed to conduct trials with us. The Deco was extremely successful in producing the parts; its ability to change from one variant to another quickly enabled us to quote competitively."

AEL competitors with alternate sliding head lathes were bidding for the same job but were having difficulty efficiently machining components from hexagonal bar. The customer specification dictated that the bar must be bead blasted prior to machining to give the ultimate finish required. As all users of sliding head machines will be aware, the guide bush will leave a witness, which on normal hexagon work is acceptable.

Competitors using alternative sliding head technology were unable to satisfy the customer's stringent requirements. In addition to marking, the competitors also had difficulty drilling a 0.3mm diameter hole 9mm deep through the component. A combination of the rigidity of the Tornos backed up by the Tornos engineers' ability to draw from world wide experience of difficult applications and appropriate tooling, paved the way for AEL to successfully produce samples and ultimately win the contract. The 13 employee company now produces the component in 2.5 minutes whilst competitors could only manage a handful of parts in two weeks.
