In excellent condition and ready for use, this CNC machining center offers high-quality performance and versatility that makes it suitable for a wide range of applications.
The Doosan Daewoo DNM 650 II features a very generous work area: the X-axis travel reaches 1270 mm , the Y-axis travel 670 mm , and the Z-axis travel 625 mm . These measurements allow you to machine large workpieces with maximum precision. The table measures 1300 x 670 mm and has a load capacity of up to 1000 kg , so it can handle heavy and bulky workpieces without problems.
One of the most interesting features of this machine is the spindle with an ISO SK 40 connection , which reaches a maximum speed of 8000 rpm 18.5 kW spindle motor (for 15 minutes), this machining center offers excellent performance even for machining operations that require high speeds. The tool changer can accommodate up to 30 tools , ensuring quick changes and greater operational efficiency, especially in series production.
The Doosan Daewoo DNM 650 II is particularly versatile and can be used to machine various materials such as steel, aluminum, and other metals. It is equipped with a HEIDENHAIN , known for its precision and ease of programming, ideal for complex and high-precision machining.
The machine is also equipped for a fourth axis, with the addition of a Nikken for the fourth and fifth axes, enabling even more complex machining operations on three-dimensional parts. This makes the Doosan Daewoo DNM 650 II a perfect solution for companies operating in sectors such as automotive, aerospace, or precision engineering.
To optimize the operation of the Doosan Daewoo DNM 650 II , it is essential to calculate the ideal cutting parameters. For example, the cutting speed ( Vc ) can be calculated using the formula:
Vc=π⋅D⋅n1000Vc = \frac{\pi \cdot D \cdot n}{1000}
Where:
Furthermore, the feed per tooth ( fz ) is calculated as:
fz=Vfn⋅zfz = \frac{Vf}{n \cdot z}
Where:
By using these formulas, you can ensure that your machine performs optimally, improving the quality of your machining and reducing tool wear.
Regular maintenance is essential to keep the Doosan Daewoo DNM 650 II in tip-top condition. Regularly checking the cooling system and chip conveyor is essential to ensure smooth operation and prevent blockages. The machine also features a built-in cooling system, which ensures temperature control during intensive operations.
This machining center complies with CE safety regulations, but as with any used machine, it is important to verify the correct functioning of all safety systems, such as emergency buttons and physical protections.
The Doosan Daewoo DNM 650 II is perfect for a variety of industries, including industrial automation, mechanical parts manufacturing, aerospace, and automotive. Buying a used machine is an excellent opportunity, as it allows you to obtain a high-performance machine at a much lower price than a new one. For €75,000 , you can get a complete, tested, and ready-to-use CNC machining center, without having to wait for long delivery times. Furthermore, since it's a used but well-maintained machine, the risk of malfunctions is minimal, and you can leverage your investment immediately.
In conclusion, the Doosan Daewoo DNM 650 II , with its excellent technical features, reliability, and ability to process large workpieces, is an excellent option for those looking to expand their production capacity without the expense of a new machine.
