USED DOOSAN DNM 350/5AX 2016

The DOOSAN DNM 350/5AX 2016 is a 5-axis CNC vertical machining center designed for manufacturers that need simultaneous multi-axis machining, complex contouring, and reduced setup times. Manufactured by Doosan Machine Tools, now part of DN Solutions, the DNM 350/5AX belongs to the DNM series of high-performance vertical machining centers.

The machine is designed around a compact 5-axis configuration that allows manufacturers to machine complex components in fewer setups. This is particularly valuable when machining parts with multiple angled surfaces, deep cavities, compound contours, and difficult-to-reach features.

The DNM 350/5AX is well suited to aerospace, automotive, medical, mold and die, energy, defense, and precision engineering applications. The machine’s 5-axis capability can reduce the need for multiple fixtures and repositioning, improving consistency between different features of a component.

A 2016 machine can have different spindle, control, rotary table, probing, coolant, and tool-magazine configurations, so the exact machine should be checked using its serial number and original factory build sheet before confirming every specification.

DOOSAN DNM 350/5AX 2016 – AXIS

The compact work envelope is designed around 5-axis machining rather than simply providing long linear-axis travel. This allows the machine to access multiple surfaces of a component without repeatedly removing and repositioning the workpiece.

DOOSAN DNM 350/5AX 2016 – WORK ENVELOPE

The integrated rotary table is the key feature of the DNM 350/5AX. It allows the workpiece to be tilted and rotated during machining, providing access to multiple faces and complex geometries.

DOOSAN DNM 350/5AX 2016 – SPINDLE

The spindle configuration can vary on used DNM 350/5AX machines. Buyers should verify the actual spindle speed, motor power, taper, and coolant package from the machine’s documentation.

For a used 5-axis machine, spindle condition is particularly important. The spindle should be checked for runout, bearing noise, vibration, temperature rise, tool retention, and performance throughout the available RPM range.

DOOSAN DNM 350/5AX 2016 – 5-AXIS ROTARY SYSTEM

The integrated 5-axis system allows machining operations to be performed from multiple orientations. This can reduce setup time and improve positional consistency because multiple features can be completed without removing the workpiece.

DOOSAN DNM 350/5AX 2016 – TOOL CHANGER

The automatic tool changer enables the machine to perform complex multi-operation programs with minimal operator intervention.

For used-machine buyers, the ATC should be tested through repeated tool-change cycles. Tool-change errors, arm movement, drawbar operation, tool-pocket condition, and spindle orientation should all be inspected.

DOOSAN DNM 350/5AX 2016 – FEEDRATES

Actual rapid and cutting-feed rates depend on the specific 2016 machine configuration and control package.

DOOSAN DNM 350/5AX 2016 – CONTROL SYSTEM

The control system provides the interpolation and motion management required for simultaneous 5-axis machining. Exact control model and software options should be confirmed from the machine’s serial number.

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

Through-spindle coolant and chip evacuation are particularly useful for deep-hole drilling, pocket machining, and complex 5-axis work where chips can accumulate in difficult-to-access areas.

DOOSAN DNM 350/5AX 2016 – PRECISION AND RIGIDITY

The machine’s rigid construction is important when machining hard materials and complex geometries. In a used 5-axis machine, rotary-axis condition is just as important as the linear axes.

DOOSAN DNM 350/5AX 2016 – GENERAL INFORMATION

Individual 2016 machines may differ in spindle, control, rotary table, ATC, coolant, probing, and automation specifications. These should be verified before publishing a final machine listing.

INDUSTRIES THAT USE DOOSAN DNM 350/5AX 2016

Typical operations include 5-axis contouring, face milling, pocketing, drilling, tapping, boring, profiling, chamfering, engraving, and multi-sided machining.

WHY CHOOSE DOOSAN DNM 350/5AX 2016

The biggest advantage of the DOOSAN DNM 350/5AX 2016 is its integrated 5-axis capability. Instead of machining a component in several separate setups, the machine can position the workpiece to reach multiple surfaces and features.

This can reduce setup time, improve feature-to-feature accuracy, and reduce the possibility of errors caused by repeatedly removing and repositioning a component.

The machine is particularly valuable for complex aerospace, medical, mold, die, and automotive components. Parts with angled holes, compound surfaces, deep pockets, and multiple machining orientations can benefit significantly from 5-axis machining.

The DNM platform is also known for providing a practical combination of rigidity, productivity, and relatively compact machine dimensions.

WHY BUY USED DOOSAN DNM 350/5AX 2016

Buying a used DOOSAN DNM 350/5AX 2016 can provide a manufacturer with access to 5-axis machining capability at a substantially lower cost than purchasing a new 5-axis machining center.

A used machine can be particularly attractive when it has low spindle hours, accurate rotary axes, good linear-axis condition, a functional automatic tool changer, and a complete maintenance history.

The ability to complete several operations in a single setup can also improve productivity and reduce fixture requirements. This can be especially valuable when producing complex components in small and medium production runs.

When evaluating a used DNM 350/5AX, buyers should inspect the main spindle, spindle taper, drawbar, X/Y/Z ballscrews, linear guides, rotary A/C axes, rotary-table bearings, backlash, rotary positioning accuracy, tool changer, CNC control, coolant system, chip conveyor, lubrication system, electrical cabinet, and probing system.

A full 5-axis test cut and rotary-axis calibration check should be performed before purchase whenever possible.

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

The price of a used DOOSAN DNM 350/5AX 2016 depends on the machine’s spindle hours, rotary-axis condition, control, spindle specification, ATC capacity, probing, coolant system, chip conveyor, tooling, and location.

Five-axis machines can have a considerably wider price range than comparable 3-axis VMCs because the condition and accuracy of the rotary system have a major impact on value.

For used-equipment listing purposes, a reasonable working estimate for a used DOOSAN DNM 350/5AX 2016 is approximately $70,000 to $110,000 USD, depending heavily on machine condition, hours, configuration, tooling, and included accessories.

A low-hour machine with a healthy spindle, accurate A/C rotary axes, strong geometric accuracy, functional ATC, probing, through-spindle coolant, chip conveyor, and complete maintenance records can command a premium.

Before establishing the final selling price, buyers should verify spindle hours, cutting hours, spindle runout, spindle bearing condition, X/Y/Z-axis accuracy, ballscrew backlash, linear-guide condition, A/C rotary-axis accuracy, rotary backlash, ATC operation, drawbar condition, control functionality, probing, coolant system, chip conveyor, lubrication system, electrical condition, tooling, and overall 5-axis machine geometry.
