The Doosan DNM 4000 is a compact, high-speed CNC vertical machining center (VMC) designed for precision machining, high productivity, and space-efficient manufacturing environments. It is part of the newer DNM series and is specifically engineered for shops that require full machining capability in a smaller footprint without compromising performance.
This machine features a rigid Meehanite cast iron structure combined with roller-type linear guideways, ensuring excellent stability, reduced vibration, and long-term accuracy. The DNM 4000 is equipped with a direct-coupled BIG-PLUS CAT 40 spindle capable of speeds up to 12,000 RPM and delivering approximately 18.5 kW (25 HP) of power and 117–118 Nm of torque. This design eliminates belt losses, improves surface finish, and enhances cutting efficiency across a wide range of materials.
With travels of approximately 520 × 400 × 480 mm, the machine is ideal for small to medium-sized parts. Despite its compact size, it offers high rapid traverse rates of up to 48 m/min on all axes, making it extremely productive for high-cycle machining.
The DNM 4000 is commonly equipped with FANUC controls and includes features such as through-spindle coolant, thermal compensation, and tool monitoring, making it suitable for industries like aerospace, medical, die & mold, and precision engineering.
