The used Doosan DNM 350 is a compact CNC vertical machining center designed for high-precision milling, excellent rigidity, and efficient performance in smaller work envelopes. It is commonly used for machining small to medium-sized components such as precision parts, molds, medical components, and complex geometries requiring tight tolerances.
This machine is well suited for milling, drilling, tapping, and contouring operations across materials like aluminum, steel, stainless steel, and alloys. The DNM 350 is known for its compact footprint combined with high-speed capability, making it ideal for shops where space efficiency and precision are critical. It is often equipped with a Fanuc control and a BT40 spindle, providing reliable and user-friendly operation.
In many configurations (especially 5AX variants), the machine can support multi-axis machining, enabling complex part production in fewer setups. When evaluating a used DNM 350, buyers should inspect spindle condition, axis accuracy, tool changer performance, and overall maintenance history.

WHY BUY USED DOOSAN DNM 350
Buying a used Doosan DNM 350 is a strong choice for shops that need a precise and compact vertical machining center. One of the biggest advantages is its footprint-to-performance ratio—offering high capability without requiring large floor space.
Another key benefit is precision. The machine is designed for high-speed machining with stable structure and optimized column design, which helps maintain accuracy during continuous operations.
The DNM 350 is also highly versatile. It can handle everything from general machining to more complex parts (especially in 4th/5th axis setups), making it suitable for industries like aerospace, medical, and electronics.
HOW MUCH DOES A USED DOOSAN DNM 350COST?
The price of a used Doosan DNM 350 depends on configuration (3-axis vs 5-axis), machine year, condition, control system, tooling, and options.
Typical pricing ranges:
Pre-2015 models: around $30,000 to $70,000
2015–2020 models: around $60,000 to $120,000
2020–2025 models: around $120,000 to $180,000+
For example, a 2021 5-axis configuration has been listed around $160,000+, depending on condition and included options.
Machines equipped with 5-axis capability, through-spindle coolant, probing systems, and larger tool magazines typically command higher prices.
