The Doosan DNM 350 (commonly available as the DNM 350/5AX) is a high-precision 5-axis CNC vertical machining center designed for complex, multi-surface machining in a single setup. It represents the next step up from smaller 5-axis machines like the DNM 200/5AX, offering a larger work envelope and higher capacity while maintaining a compact footprint.
This machine features a trunnion-style rotary table (A-axis tilt and C-axis rotation), enabling full simultaneous 5-axis machining as well as 3+2 positioning. This allows manufacturers to machine intricate geometries, reduce setups, and significantly improve accuracy by eliminating repositioning errors.
Built on Doosan’s proven DNM platform, the machine incorporates a rigid column-type structure with roller-type linear guideways, ensuring excellent stability, high feed rates, and long-term accuracy. It is equipped with a direct-coupled spindle capable of up to 12,000 RPM and approximately 18.6 kW of power, making it suitable for both high-speed and moderate heavy-duty cutting.
With a larger rotary table (~350 mm) and higher load capacity (~250 kg), the DNM 350 is ideal for industries such as aerospace, medical, automotive, and mold & die, especially for medium-sized complex components.

WHY BUY USED DOOSAN DNM 350
Buying a used Doosan DNM 350 is an excellent way to access advanced 5-axis machining capabilities at a significantly reduced cost.
One of the biggest advantages of this machine is its increased capacity compared to smaller 5-axis models. With a larger workpiece envelope and higher table load, it allows shops to machine bigger and more complex parts without stepping up to a much larger and more expensive machine.
Another key benefit is its productivity. The ability to machine multiple faces in a single setup reduces setup time, improves accuracy, and increases overall efficiency. This is especially valuable for industries requiring tight tolerances and complex geometries.
The machine also offers high-speed performance with rapid traverse rates up to 36 m/min and a fast automatic tool changer with up to 60 tools, making it suitable for both prototyping and production work.
Additionally, the availability of Fanuc, Siemens, or Heidenhain controls ensures operator familiarity and strong service support worldwide.
HOW MUCH DOES A USED DOOSAN DNM 350COST?
The cost of a used Doosan DNM 350 (especially the 5AX version) varies depending on year, condition, and included options.
Typically, used machines range between $90,000 and $180,000. Older models or basic configurations fall on the lower end, while newer machines with advanced controls, probing systems, and high-pressure coolant can exceed $150,000+.
Recent listings for newer machines (around 2020–2021) have been seen in the range of ~$160,000, reflecting their high capability and relatively modern design.
Overall, the DNM 350 offers strong value for shops looking to expand into 5-axis machining with a larger capacity machine.
