Mills Manufacturing Technology has launched the DNM range of Doosan vertical machining centres in the UK and Ireland.
The DNM machine range is aimed at precision component manufacturers and toolmakers.
The range consists of two models – the DNM 400, DNM 500 and DNM 650.
The 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.
All machines in the range have a generous working envelope, enabling large parts and/or multiple parts to be machined.
Tables are fully supported by the saddle and there is no table overhang, which ensures higher accuracy.
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 106Nm.
Power is transmitted via a heavy duty cogged drive belt that ensures thermal stability and maximum vibration.
Spindle and machining performance is further ensured by the dual contact system (Big Plus) between the spindle face and toolholder flange.
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 ATCs (40-position option), which has a 1.3s tool modify time.
The performance of the DNM machines can be further improved by a range of options that include: fourth-axis preparation; automatic tool and workpiece measurement; chip conveyor; and a through-spindle-coolant system.
The machines are equipped with the Fanuc I-series control and are supplied with a number of fully functional and user-friendly Doosan program programs for fast job set-up, real-time monitoring and intervention, and improved process reliability.
