USED DOOSAN DNM 750L

The Doosan DNM 750L is a large-format CNC vertical machining center (VMC) specifically engineered for machining long and oversized workpieces with high precision and stability. The “L” in the model name stands for long-bed configuration, offering significantly extended X-axis travel compared to standard models like the DNM 750 II, making it ideal for large plates, structural components, and multi-part setups.

Built with a rigid Meehanite cast iron structure and wide roller-type linear guideways, the DNM 750L ensures excellent rigidity, reduced vibration, and long-term dimensional accuracy even across its extended travel range. The machine typically features a BIG-PLUS CAT 40 spindle running at 12,000 RPM with approximately 21 HP, delivering a strong balance of speed and torque for both heavy cutting and finishing operations.

With axis travels of approximately 2,160 × 762 × 650 mm (85″ × 30″ × 25.6″), the DNM 750L provides a very large working envelope. This makes it ideal for industries such as aerospace, die & mold, heavy fabrication, and general machining where long components and high precision are required.

Advanced features such as thermal compensation, spindle cooling, through-spindle coolant, and probing readiness ensure consistent accuracy, improved tool life, and enhanced productivity in demanding environments.

WHY BUY USED DOOSAN DNM 750L

Buying a used Doosan DNM 750L is a strong investment for manufacturers needing extended machining capacity without the high cost of a new large-format VMC.

One of the biggest advantages is its long X-axis travel (85 inches), which allows machining of oversized parts or multiple components in a single setup. This significantly reduces setup time and increases productivity in production environments.

Another key benefit is its rigidity and stability. The reinforced structure, wide guideways, and high load capacity (up to ~1,800 kg) ensure consistent performance even during heavy-duty cutting operations.

The machine is also highly productive. With rapid traverse rates up to ~24 m/min, fast tool change times (~1.3 seconds tool-to-tool), and a 30-tool automatic tool changer, it minimizes idle time and supports efficient machining.

Additionally, the use of FANUC controls ensures ease of operation, reliability, and global support availability. Many used machines also include options like through-spindle coolant, chip conveyors, and probing systems, further increasing their value.

HOW MUCH DOES A USED DOOSAN DNM 750L COST?

The cost of a used Doosan DNM 750L depends on factors such as year, condition, spindle hours, and included options.

Typically, used machines range between $70,000 and $150,000. Older models (2013–2015) are generally on the lower end, while newer or well-equipped machines with features like high-pressure coolant, probing systems, and larger tool magazines command higher prices.

Machines with enhanced configurations such as 4th-axis capability, automation readiness, and upgraded spindle performance tend to have higher resale value due to increased flexibility and productivity.

Overall, the DNM 750L offers excellent value for manufacturers needing a large, long-bed VMC capable of handling demanding applications.
