Cogsdill-Nuneaton Ltd, a leading supplier of specialist tooling solutions, has recently invested in a new DNM 6700 high-performance Doosan vertical machining centre from Mills CNC (www.millscnc.co.uk), the exclusive distributor of Doosan machines in the UK and Ireland.

It was installed in May and is currently being used to machine precision components for Cogsdill’s range of ZX facing- and contouring-head tooling systems (example pictured).

These components include different-size front-mounted cross-slides, which are machined from nitrided and carbon steel. The decision to invest in the new machining centre followed an internal review of Cogsdill’s existing CNC machine tool capabilities.

With international demand for its larger tooling solutions on the increase, it became clear that a reliable large-capacity vertical machining centre was required.

Lee Donaldson, Cogsdill UK director, said: “To ensure that we purchased a vertical machining centre that matched our needs and expectations, we did our homework and created a ‘key criteria’ check-list before investigating the market.

"Although we hadn’t invested in a Doosan machine tool previously, we knew that Doosan machine tools have a good reputation in the market, and that Mills CNC is a successful company with a significant market presence.”

Cogsdill also had experience of working with both Doosan and Mills CNC as a technical partner, supplying advanced tooling solutions to both.

Mr Donaldson said: “The working envelope of the machine was of critical importance, and the DNM 6700’s large-capacity enables us to machine larger components — as well as smaller components — in a single set-up.

"This means faster production and reduced part cycle times. Similarly, the cutting performance of the machine was important; the DNM 6700’s powerful and direct-drive spindle technology gives us the ability to achieve high removal rates when required, as well as fine finishes. It is a very versatile machine.”
