New Doosan vertical machine tool range provides real
Market-leading machine tool specialist Mills Manufacturing Technology Ltd has recently launched a new range of high-performance Doosan vertical machining centres into the UK and Ireland.
The DNM machine range is aimed at precision component manufacturers and toolmakers, and provides users with high productivity, exceptional accuracy, and optimised process reliability.
There are 3 models in the new range -: DNM 400; DNM 500 and DNM 650.
The DNM machines have a rigid design and construction which delivers improved vibration absorption capability. Machine beds, manufactured from heavily-ribbed Meehanite, and column assemblies have been designed for trouble-free high-speed and heavy-duty machining operations.
The DNM machines are kinematically-sound. Tables are fully supported by the saddle and there is no table overhang which ensures higher accuracy. All machines in the range have a generous working envelope, enabling large parts and/or multiple parts to be machined.
DNM machines are equipped with high-quality spindle technology. The high-speed 40 taper spindles provide users with high torque capability (18.5kW 12,000rpm) that delivers an impressive 106N-m. Power is transmitted via a heavy-duty cogged drive belt that ensures thermal stability and minimum vibration.
Spindle and machining performance is further ensured by the dual contact system (Big Plus) between the spindle face and toolholder flange.
As well as being equipped with high-speed and high-productivity spindles, the DNM machines also feature linear guide ways and high-speed servo motors that enable fast axis movement (36m/min on X- and Y-axes; and 30m/min on Z-axis), which in turn reduces non-cutting times.
Speed is also evident in the machines' 30- tool position ATC's (40-position option), which now boasts a 1.3 second tool change time (T-T-T).
The machines are equipped with the Fanuc i-series control and are supplied with a number of fully-functional and user-friendly Doosan software programs for fast job set-up, real time monitoring and intervention, and improved process reliability.
The performance of the DNM machines can be further improved by a range of options that include -: 4th-axis preparation; automatic tool and workpiece measurement; chip conveyor and through-spindle-coolant system.
Says David Andrew Sales & Marketing Director at Mills:
‘The Doosan DNM 400, 500 and 650 are reliable, high-performance, competitively-priced machines. They have been to deliver exceptional productivity and accuracy (irrespective of cutting conditions or part complexity).
‘Doosan vertical machines, like Doosan lathes, horizontals and mill-turn centres, are proving to be the number one choice for precision manufacturers. The DNM machines will ensure that this continues to be the case.'
