USED DOOSAN DNM 6700

The Doosan DNM 6700 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 largest models in the DNM series, offering significantly more travel, table capacity, and rigidity compared to machines like the DNM 5700 or DNM 650.

Built with a robust Meehanite cast iron structure, box-type column, and roller-type linear guideways, the DNM 6700 delivers exceptional rigidity and stability during demanding cutting operations. This design minimizes vibration and ensures consistent accuracy even during long production cycles.

The machine features a BIG-PLUS CAT 40 spindle with multiple configurations, including an 8,000 RPM high-torque option (up to ~286 Nm) for heavy cutting and a 12,000–15,000 RPM high-speed option for precision and finishing work.

With axis travels of approximately 1,300 × 670 × 625 mm and a large table size around 1,500 × 670 mm, the DNM 6700 is ideal for machining large parts, base plates, and multi-part fixtures. It supports a table load capacity of up to 1,300 kg, making it suitable for heavy components.

Equipped with FANUC controls, advanced thermal compensation, and automation-ready features, the DNM 6700 is widely used in aerospace, automotive, die & mold, and general engineering industries.

WHY BUY USED DOOSAN DNM 6700

Buying a used Doosan DNM 6700 is a strong investment for shops that need large machining capacity and heavy-duty performance without the high cost of a new machine.

One of the biggest advantages is its expanded work envelope and high load capacity. Compared to smaller DNM models, this machine allows manufacturers to machine larger parts or multiple setups in a single cycle, significantly improving productivity.

Another key benefit is its powerful spindle performance. The high-torque spindle option is ideal for aggressive material removal in steel and cast iron, while the high-speed spindle provides flexibility for aluminum and precision finishing applications.

The DNM 6700 is also designed for high productivity. With rapid traverse rates of up to 36 m/min, fast tool change times (~1.2 seconds tool-to-tool), and tool magazine options up to 60 tools, it supports efficient, high-volume production.

Additionally, features such as thermal compensation, adaptive feed control, and tool load monitoring help maintain accuracy, reduce tool wear, and minimize downtime—making it ideal for both job shops and production environments.

HOW MUCH DOES A USED DOOSAN DNM 6700 COST?

The cost of a used Doosan DNM 6700 varies based on year, condition, spindle configuration, and included options.

Typically, used machines range between $60,000 and $140,000. Older machines or base configurations are on the lower end, while newer 4th-generation models with high-speed spindles, larger tool magazines, and automation-ready features can reach higher price points.

Machines equipped with options such as through-spindle coolant, probing systems, chip conveyors, and 4th-axis capability tend to command higher prices due to increased productivity and versatility.

Overall, the DNM 6700 offers excellent value for manufacturers needing a large, powerful, and production-ready vertical machining center.
