Mills CNC, the exclusive distributor of Doosan machine tools in the UK and Ireland, has introduced two Doosan five-axis machining centres.

The two machines – the DVF 6500 (650 mm diameter table) and the larger capacity DVF 8000 (800 mm diameter table) – are from the same stable as the Doosan DVF 5000 machine that was launched 18 months ago.
Both machines are compact and have a rigid structure for increased accuracy, improved surface finish and greater process reliability. The new models boast 45 m/min rapid traverse rates and are equipped with oil-cooled, directly-driven BT40 spindles (up to 22 kW/18,000 rpm) to suit 3+2, 4+1 or full five-axis simultaneous machining.
Also featured are servo-driven automatic tool changers (up to 120 tools) with a 1.3 second changeover time, roller LM guideways and direct-drive rotary tilting tables (A axis = +120/-120°; C axis = 360°).
The DVF 6500 and DVF 8000 machines are available with a choice of control (Fanuc 31iB5, Heidenhain TNC640 or Siemens 840D with ShopMill software), and are supplied with thermal compensation systems and a long-life, grease lubrication system. A collision protection system can also be offered
as an option.
There are some differences, however. The DVF 6500 and DVF 8000 have different-sized travels (DVF 6500 = 750 x 785 x 600 mm; DVF 8000 = 1000 x 900 x 685 mm) and different table loads (up to 1000 and 1400 kg respectively).
Within the DVF 8000 range a specific ‘Turning’ model can also be specified. The DVF 8000T, with its integrated function, has the same technical specification as the DVF 8000 in most respects, except for a lighter maximum table load (700 kg) and a faster C-axis feed rate (600 rpm).
