USED DOOSAN DNM 350/5AX 2016

The DOOSAN DNM 350/5AX 2016 is a high-performance 5-axis vertical machining center designed for simultaneous 5-axis machining, complex contouring, multi-face machining, and high-precision production. Manufactured by Doosan Machine Tools, the DNM 350/5AX was developed around the proven DNM vertical machining center platform and adds a rotary 5-axis table for machining complex components in fewer setups.

A documented 2016 DNM 350/5AX is equipped with 600 mm X-axis travel, 655 mm Y-axis travel, and 500 mm Z-axis travel, a 350 mm rotary table, 12,000 RPM spindle, 30-tool automatic tool changer, and FANUC 31i-B5 control. A 2016 used example was also equipped with through-spindle coolant, spindle probe, tool setter, chip conveyor, and filtration equipment.

The DNM 350/5AX is designed for full 5-axis or 5-face machining, allowing manufacturers to machine complex workpieces from multiple directions without repeatedly repositioning the part. This can reduce setup time, improve positional accuracy, and make the machine particularly useful for aerospace, medical, automotive, mold and die, energy, defense, and precision engineering applications.

DOOSAN DNM 350/5AX 2016 – FEEDRATES

The high-speed linear axis movement helps reduce positioning time between cutting operations and supports efficient production cycles.

DOOSAN DNM 350/5AX 2016 – CONTROL SYSTEM

A documented 2016 DNM 350/5AX is equipped with a FANUC Series 31i-Model B5 control, spindle probe, tool setter, and expanded memory.

DOOSAN DNM 350/5AX 2016 – COOLANT / CHIP MANAGEMENT

A documented 2016 machine was equipped with through-spindle coolant, LNS chip conveyor, centrifugal separator, and liquid cyclone filtration, making it particularly well equipped for production machining.

DOOSAN DNM 350/5AX 2016 – MACHINE DIMENSIONS

The DNM 350/5AX is a substantial industrial machine, so transportation, rigging, floor loading, electrical service, and installation access should be evaluated before purchasing a used unit.

DOOSAN DNM 350/5AX 2016 – GENERAL INFORMATION

Specifications for an individual 2016 machine should always be verified from its serial number, build sheet, and actual installed options. This is particularly important because DNM 350/5AX specifications can differ by market and configuration.

INDUSTRIES THAT USE DOOSAN DNM 350/5AX 2016

WHY CHOOSE DOOSAN DNM 350/5AX 2016

The main advantage of the DOOSAN DNM 350/5AX is its ability to perform complex machining in five axes, reducing the number of setups needed for difficult components.

Instead of repeatedly repositioning a workpiece on a conventional three-axis VMC, the rotary table allows the cutting tool to reach multiple surfaces and angles in one setup. This can improve positional accuracy while reducing setup time and workpiece handling.

The 2016 model combines substantial 600 × 655 × 500 mm travels, a 350 mm rotary table, 12,000 RPM spindle, and 30-tool automatic tool changer.

The machine is therefore well suited to shops that require both high productivity and advanced 5-axis machining capability.

WHY BUY USED DOOSAN DNM 350/5AX 2016

Buying a used DOOSAN DNM 350/5AX 2016 can give manufacturers access to professional 5-axis machining capability at a considerably lower investment than purchasing new equipment.

The machine is particularly attractive for shops that need to manufacture complex components but want to minimize multiple setups. The rotary table, 5-axis control, high-speed spindle, automatic tool changer, and optional probing systems provide a strong combination of productivity and flexibility.

A documented 2016 machine was equipped with FANUC 31i-B5, spindle probe, tool presetter, through-spindle coolant, chip conveyor, and filtration equipment, demonstrating the range of production-oriented options that may be available on used examples.

When purchasing a used machine, inspect the rotary table carefully. A-axis and C-axis backlash, rotary positioning accuracy, clamp/unclamp operation, spindle bearings, ballscrews, linear guides, tool changer, control electronics, probing system, coolant system, and machine geometry should all be evaluated.

HOW MUCH DOES A USED DOOSAN DNM 350/5AX 2016 COST?

The price of a used DOOSAN DNM 350/5AX 2016 depends heavily on spindle hours, cutting hours, machine condition, CNC control, rotary-table accuracy, tooling, probing, through-spindle coolant, chip conveyor, filtration, and service history.

A documented 2016 DNM 350/5AX was listed as being in excellent condition, with a stated replacement cost of approximately $250,000 USD. That figure represents replacement cost rather than the actual used-market value.

For used-equipment listing purposes, a reasonable broad estimate for a DOOSAN DNM 350/5AX 2016 is approximately $90,000 to $160,000 USD, depending on condition, hours, options, tooling, and location.

Machines with low spindle hours, accurate rotary axes, FANUC 31i-B5 control, probing, tool presetting, through-spindle coolant, chip conveyor, and filtration can command a premium. Machines requiring rotary-axis repair, spindle work, control repairs, or major mechanical refurbishment can be worth considerably less.

Before determining the final market value, buyers should run the machine under power and check 5-axis interpolation, A/C-axis positioning, rotary backlash, spindle vibration, spindle temperature, tool changer operation, axis accuracy, probing, coolant delivery, chip conveyor, and machine geometry.
