The Doosan DNM 4500 is a mid-size, high-performance CNC vertical machining center (VMC) designed for precision machining, production efficiency, and long-term reliability. As part of the latest DNM series (including 4th generation models), it represents a balance between compact footprint and expanded machining capacity, making it ideal for shops that need more travel than smaller machines like the DNM 4000 while maintaining high-speed capability.
This machine is built with a rigid Meehanite cast iron structure and roller-type linear guideways, ensuring excellent vibration damping, thermal stability, and consistent accuracy even during extended production runs. It is equipped with a BIG-PLUS CAT 40 direct-coupled spindle, typically offering 8,000 RPM (high torque) or optional 12,000–15,000 RPM configurations for high-speed machining.
With axis travels of approximately 800 × 450 × 510 mm (31.5″ × 17.7″ × 20.1″), the DNM 4500 provides a larger work envelope suitable for medium-sized parts. The machine is also equipped with advanced features such as thermal compensation, tool load monitoring, and through-spindle coolant, ensuring high accuracy and productivity in demanding applications.
It is widely used in industries such as aerospace, automotive, tool & die, and general manufacturing due to its versatility, durability, and consistent performance.

WHY BUY USED DOOSAN DNM 4500
Buying a used Doosan DNM 4500 is an excellent option for manufacturers looking to upgrade to a larger and more capable VMC without the cost of a new machine.
One of the biggest advantages of this machine is its increased work envelope compared to smaller models like the DNM 400 or 4000. This allows shops to handle larger parts and more complex setups while still maintaining a relatively compact footprint.
Another key benefit is its strong spindle performance. The availability of both high-torque (8,000 RPM) and high-speed (15,000 RPM) spindle options makes it suitable for a wide range of materials—from heavy steel cutting to high-speed aluminum machining.
The DNM 4500 is also built for productivity. With rapid traverse rates up to 36–42 m/min and fast tool change times (~1.2 seconds), it significantly reduces cycle times in production environments.
Additionally, the machine includes modern features such as thermal monitoring, adaptive feed control, and probing readiness, which help maintain accuracy and reduce downtime. Combined with FANUC controls, this ensures ease of operation, reliability, and strong global support.
HOW MUCH DOES A USED DOOSAN DNM 4500COST?
The cost of a used Doosan DNM 4500 depends on factors such as year, condition, spindle hours, and included options.
Typically, used machines range between $45,000 and $100,000. Older models or base configurations fall on the lower end, while newer 4th generation machines with advanced features, larger tool magazines, and automation-ready options can command higher prices.
Newer machines are priced significantly higher due to improved thermal stability, higher speeds, and built-in smart monitoring systems, making used machines a strong value option for shops looking to expand capacity without a large capital investment.
Overall, the DNM 4500 offers an excellent balance of size, performance, and cost, making it one of the most popular mid-size VMCs in the used market.
