Doosans for precision engineers and toolmakers

Doosan DNM vertical machining centres are aimed at precision component manufacturers and toolmakers.

The three model range (DNM 400; DNM 500 and DNM 650) boasts a rigid design and construction for 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, says Mills Manufacturing Technology.

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.

High speed 40 taper spindles provide users with high torque capability (18.5 kW/12,000 rpm) that delivers an impressive 106 Nm. Power is transmitted via a heavy duty cogged drive belt that ensures thermal stability and minimum vibration.

DNM machines also feature linear guide ways and high speed servo motors that enable fast axis movement (36 m/min on X and Y-axes and 30m/min on the Z axis). Speed is also evident in the machines’ 30-tool position ATCs (40-position option), which now boasts a 1.3 second tool change time.
