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.

WHY BUY USED DOOSAN DNM 400
Buying a used Doosan DNM 4000 is a strong investment for shops looking for modern performance, high speed, and compact efficiency at a reduced cost.
One of the biggest advantages of this machine is its compact footprint with full machining capability. It is specifically designed for lean manufacturing cells and space-constrained environments, allowing shops to maximize floor utilization without sacrificing productivity.
Another key benefit is its high-speed performance. With rapid traverse rates of 48 m/min and a direct-drive spindle, the machine delivers fast cycle times, improved surface finishes, and longer tool life. This makes it ideal for high-volume production of small precision parts.
The DNM 4000 also includes advanced features such as thermal compensation, adaptive feed control, and tool load monitoring, which help maintain accuracy and protect tooling during extended operations. Additionally, the use of FANUC controls ensures ease of programming, strong reliability, and global service support.
HOW MUCH DOES A USED DOOSAN DNM 400COST?
The cost of a used Doosan DNM 4000 varies depending on year, condition, spindle hours, and included options.
Typically, used machines range between $40,000 and $90,000, depending on configuration and condition. Machines with options such as through-spindle coolant, probing systems, and automation readiness (robot integration, pallet systems) tend to be priced higher.
Since the DNM 4000 is a relatively newer model compared to older DNM series machines, it generally commands a higher resale value due to its advanced features, faster speeds, and improved efficiency.
Overall, it offers excellent value for manufacturers seeking a modern, compact, high-speed machining center.
