Doosan has many series of vertical machining centers, among which the DNM series compact high productivity vertical machining centers are the most popular series with higher productivity, more reliable configuration and structure. The DNM series adopts the design concept of high rotation and high rigidity, and is equipped with direct-connected spindle and roller guideway to provide customers with a good machining experience.The DNM series has a wide range of specifications in the lineup, which can be machined in a wide range to cope with diversified and high-efficiency machining.

The most popular models of the DNM series are these: DNM4505, DNM5705, DNM6705. These models have the following 6 advantages:

1. Highly rigid structure

• Highly Stable Body Structure

DNM adopts finite element stress analysis method to analyze the bed structure. Thickening and widening the key structure to increase the stability of the bed while the overall volume remains unchanged.

• Stable and fast axis feed structure

All axes are equipped with roller-type linear guides, which are lubricated with environmentally friendly grease. Roller type linear guide is characterized by high rigidity and high efficiency. It has obvious advantages in terms of load bearing and service life. The acceleration of all axis feed systems has been increased by 50% compared to previous models.

• More size options

The DNM series is available in three different sizes to meet the machining needs of parts in a wide range of industries. Expanded table size and maximum load capacity provide more machining space.

2. High Performance Spindles

• High-speed, high-performance spindle

Equipped with a high-performance direct-connected spindle, this spindle improves machining accuracy by dramatically reducing the vibration and thermal errors that occur during high-speed machining of the spindle. Acceleration and deceleration times have been reduced by 70% compared to previous models.

• Spindle cooling system

The 12000r/min (optional) spindle is equipped with a spindle oil cooler as standard to ensure continuous operation of the spindle at high speeds for long periods of time. The cooled oil is circulated to the spindle bearings and the built-in motor to minimize thermal errors and ensure highly accurate cutting.

• Double-sided tool clamping system

Tool rigidity is increased by tightly clamping the spindle, while tool life cycle and cutting surface roughness are improved by reducing vibration with double-sided locking.

Rico supplies DN machining spindle accessories, such as DN spinlde draw bar, draw bar, ball screw, ballscrew, ball bearing, spring disc, etc.

3. Highly reliable tool changer

• ATC (Automatic Tool Changer)

The improved ATC makes tool change faster, shortens non-cutting time, and dramatically increases productivity. Tool change time has been reduced by 20% and chip cutting time by 14%.

• Large-capacity tool magazine

The large-capacity tool magazine allows multiple tools to be clamped at one time, eliminating the need to make up tools during machining and dramatically saving cutting time. The tool magazine is available in 24, 30 and 40 positions.

There are many sizes tool pot/tool pocket for DNM sereis, such as BT40, DIN40, BT50, DIN50 tool pot.

4. Ease of use

• Easy-to-use operation panel

The rotary operation console is extremely easy to use and can be rotated from 0-90 degrees.

• 10.4" color TFTLCD monitor

Wide display shows more information to the operator. Customized pages make installation, operation and monitoring of the machine condition easy.

• PCMCIA Card

The PCMCIA card can upload and download NC programs, NC parameters, tool information and ladder programs, and also supports DNC operation.

• USB Port

Allows uploading and downloading of NC software programs, NC parameters, tool information, and ladder programs using a USB drive, but does not support DNC operation.

• Portable MPG

Allows customers to set up workpieces easily and fundamentally. 

There are MPG and MPG encoders supplied here.

5. Good machining capability

Carbon Steel Surface Milling

Carbon Steel Drilling

Carbon Steel Tapping

6. Various optional configurations

• Chip conveyors and chip conveyors

• Grease Lubrication Systems

• Skimmers

• Chip handling systems

As more and more customers use DNM series machines, the supply of supporting accessories will be more and more, Rico, as a one-stop supplier of accessories, can provide all kinds of accessories for DN solution, please contact us for more information.
