The Doosan DNM 650 is a large-capacity CNC vertical machining center (VMC) designed for heavy-duty machining, high productivity, and precision manufacturing of medium to large components. It is one of the larger models in the DNM series, offering significantly more travel and table capacity compared to machines like the DNM 500 or 5700.
Built with a rigid Meehanite cast iron structure and linear motion (LM) guideways, the DNM 650 delivers excellent stability, reduced vibration, and long-term accuracy even under heavy cutting conditions. The machine is typically equipped with a CAT/BT 40 spindle capable of 8,000–12,000 RPM, with high-speed versions reaching up to 15,000 RPM for demanding applications.
With axis travels of approximately 1,270 × 670 × 625 mm and a large table size around 1,300 × 670 mm, the DNM 650 is ideal for machining large plates, structural components, and multi-part setups. It supports a table load of up to 1,000 kg, making it suitable for heavy workpieces.
Equipped with FANUC controls, high-speed ATC, and efficient chip management systems, the DNM 650 is widely used in industries such as automotive, aerospace, die & mold, and general engineering.

WHY BUY USED DOOSAN DNM 650
Buying a used Doosan DNM 650 is an excellent option for shops needing a larger machining platform without the cost of a new machine.
One of the biggest advantages is its large work envelope and high load capacity. The machine allows manufacturers to handle bigger parts and multiple fixtures in a single setup, improving efficiency and reducing setup time.
Another key benefit is its strong spindle performance. With up to 12,000–15,000 RPM and solid torque output, the DNM 650 can handle both heavy material removal and high-speed finishing operations across a wide range of materials.
The machine is also highly productive. It features a 30-tool automatic tool changer with fast tool change times (~1.3 seconds tool-to-tool), along with rapid traverse rates up to 36–48 m/min, helping reduce cycle times in production environments.
Additionally, the DNM 650 is known for its reliability and ease of maintenance. With widely used FANUC controls and robust construction, it ensures long service life and strong support availability.
HOW MUCH DOES A USED DOOSAN DNM 650COST?
The cost of a used Doosan DNM 650 varies based on year, condition, and included options.
Typically, used machines range between $45,000 and $110,000. Older models (2010–2013) are generally on the lower end, while newer machines or those equipped with features such as through-spindle coolant, probing systems, and 4th-axis capability command higher prices.
Machines with high-speed spindles (12K–15K RPM), chip conveyors, and automation-ready configurations tend to have higher resale value due to increased productivity and flexibility.
Overall, the DNM 650 offers excellent value for shops looking for a large-capacity, production-ready VMC with strong performance.
