Spindle Head

Spindle Max. Speed:

12,000 r/min (direct-coupled spindle option minimizes noise and vibration and reduces spindle start/stop time.)

2-Face Locking Tool System (B1G PLUS)

The 2-face locking tool system offers longer tool life, higher power, and more precise machining by making dual contact with both the spindle surface and tool holder flange surface, as well as the spindle taper and tool holder taper shank.

Taper Contact

Flange Contact

Thermal Displacement Compensation System

Y, Z Displacement:

Thermal error is minimized with the thermal deviation displacement compensation system.

75 algorithms are used to calculate Y/Z axis heat displacement caused by specific spindle improvement running conditions (r/min and time).

Drain Catcher

Removes moisture in the compressed air in solenoid valves and cylinders, extending the service life of the pneumatic system.

Spindle Head Cooling System

Option for 8,000 r/min, standard for 12,000 r/min.

The Spindle Head Cooling System is offered for long, continuous operation. The system circulates cooled oil around the spindle bearing to prevent thermal displacement and guarantee high-accuracy cutting.

High Rigidity Roller-Type LM Guide

The ball-type LM Guide is replaced with a roller-type LM Guide to improve cutting performance and surface roughness.

Service life is also extended to more than double compared to ball-type LM Guides.

Rigidity and feed rates are improved with the roller-type LM Guide and coupling.

Wide Cutting Area

Various shapes can be processed across different models:

DNM 4000: X-axis 762 mm (30 in), Y-axis 435 mm (17 in), Z-axis 510 mm (20 in)

DNM 5000: X-axis 1020 mm (40 in), Y-axis 540 mm (21 in), Z-axis 510 mm (20 in)

DNM 6500: X-axis 1270 mm (50 in), Y-axis 670 mm (26 in), Z-axis 625 mm (25 in)

Static Rigidity

The highly rigid body raises the static stiffness by 30% compared to the previous model.

Dynamic Rigidity

Frequency response and vibration attenuation performance have been improved. The high frequency has increased by 35% compared to the previous models.

Designed with FEM (Finite Element Method) to implement a stable machine structure.

Improved Usability

Easy Operation Package:

Doosan’s easy operation software package is customized to provide fast and easy operation for tooling, workpiece, and program setup.

These features maximize productivity by minimizing time lost during process setup.

Data Registry Table

Provides tool information for 2D graphics to guide the operator for troubleshooting in case of emergency stops or abnormal operation of the ATC.

Tool Load Monitoring

Damage to tools is minimized by monitoring the axis and spindle load during cutting operations.

Operator Panel

The operator panel is integrated for convenient usage. Additionally, customized function switches can be attached to maximize operator convenience.

USB Port Swiveling Operating Console:

The operation panel can be rotated by up to 90 degrees for convenient operator position. The control panel supports a wide selection of detailed alarm messages, which makes fault-finding easier.

Fixture Clamp/Unclamp Button:

Easily accessible for quick workpiece adjustments.

Portable MPG (Manual Pulse Generator):

Portable MPG buttons can be placed on the panel to set a workpiece easily, with partitions between all buttons to prevent unintended presses.
