Mills CNC, distributor of Doosan machine tools in UK and Ireland, has recently installed a new Doosan 3-axis vertical machining centre at NIACE, the Northern Ireland Advanced Composite & Engineering Centre, based in Belfast, Northern Ireland.
The machine, a DNM 400 II equipped with a Siemens 828 Control and the on-board ShopMill conversational programming software system, is being used to train engineers from Northern Ireland in best-practice CNC programming and the machining of exotic materials and hard metals –e.g. Titanium, Titanium Alloys, Inconel etc., used increasingly, although not exclusively, in the aerospace sector.
The Doosan DNM 400 II is ideal for the high accuracy machining of exotics and hard metals, and equally ideal as a best-in-class machine for training. The machine is equipped with a 12,000rpm direct-drive (in-line) spindle and a rigidly-designed and built headstock which reduces noise and vibration compared to belt-driven verticals. As a consequence, the DNM 400 II delivers superior surface finishes during fine machining operations.
The DNM 400 II’s spindle is powerful (18kW/117Nm torque) which results in improved cutting performance especially during heavy-duty operations. Performance of the DNM 400 II is further enhanced by its roller-type guide-ways.
