Tooling expert opts for Doosan vertical machining centre

Specialist tooling solutions supplier, Cogsdill-Nuneaton Ltd, invested in a new high-performance Doosan vertical machining centre for its capacity, machining capabilities, immediate availability and cost-competitiveness. Process Industry Forum reports on the features and benefits of their Doosan DNM 6700.

Precision component machining

The Doosan machine, a DNM 6700, was installed at Cogsdill’s 27,000 square foot facility earlier this year, where it is used primarily to machine precision components for their range of ZX facing and contouring head tooling systems. These components include different sized front-mounted cross slides, with slide ranges from 200mm to 900mm, which are machined from nitrided and carbon steel.

The decision to invest in the new Doosan DNM 6700 machine followed an internal review undertaken by Cogsdill into its existing CNC machine tool capabilities and, in particular, whether current milling machining capabilities were adequate to meet the growing demand from customers worldwide for its large-capacity tooling solutions.

Advanced CNC machine tool technologies

Lee Donaldson, Executive Director of Cogsdill UK, said: “We invest regularly in advanced CNC machine tool technologies and the audit and review highlighted a potential improvement opportunity within our existing CNC milling capabilities. To ensure we acquired a vertical machining centre that matched our needs and expectations we did our homework and created a ‘key criteria’ checklist before investigating the market.”

Following an extensive search into the market Cogsdill ultimately decided to invest in a new DNM 6700 vertical machining centre, sourced from Mills CNC. The DNM 6700 is a large-capacity vertical machining centre equipped with a generous sized work table (1500mm x 670mm) and impressive axis travels (X-axis:1300mm x Y-axis: 670mm x Z-axis: 625mm). The machine also features a powerful, high-torque (118N-m) direct-drive spindle (18.7kW/12,000rpm).

Faster production and reduced part cycle times

“The working envelope of the machine was of critical importance and the DNM 6700 large-capacity working envelope 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,” continued Lee.

“Similarly the cutting performance of the machine was important and the DNM 6700’s powerful and direct-drive spindle technology gives us ability to achieve high-volumetric removal rates when required as well as fine finishes. It is a very versatile machine.”
