Trio of machines installed at subcontractor

Mills CNC, the exclusive distributor of Doosan machine tools in the UK and Ireland, has supplied three new Doosan vertical machining centres to Portsmouth-based precision subcontract specialist, Penta Precision Engineering Ltd. The three machines are all Doosan DNM 4500 models.

Says Edward Moss, Penta Precision’s technical account manager: “We constantly audit and review our operational efficiency and effectiveness as part of a company-wide continuous improvement programme. As a result, we identified that some of our older machine tools were experiencing reliability issues and causing production bottlenecks. It became clear that, to help alleviate these problems, we needed to invest in new high-performance machines.
“Doosan’s DNM series of vertical machining centres are popular, proven and have a good reputation in the market,” he adds. “Having contacted Mills, we visited their facility in Leamington to see the DNM machines, and to discuss our requirements in more detail. We were impressed with their approach and by the aftersales service and support they provide to customers.”
The three Doosan DNM 4500 machines supplied to Penta Precision are all equipped with a 10.4” console, Fanuc 0iMF control (with 200 block look-ahead function), BT40 direct-coupled 18.5 kW/12,000 rpm spindle (117.8 Nm), 30-position ATC and linear guides on all axes.
In addition to the standard specification, Penta Precision also requested Renishaw spindle probes and Filtermist oil/mist extraction units on all three machines, and a Nikken rotary table on one.
“Since being installed the three DNM 4500 machines have been working flat out,” says Moss. “Our investment in Doosan machine tools from Mills CNC is having a positive impact on our productivity, performance and profitability.”
