USED DMG MORI DMC 340 U (FD)

The DMG MORI DMC 340 U (FD) is a high-performance 5-axis portal machining center designed for complete machining of large, heavy, and highly complex components in a single setup. It belongs to the DMC U Portal series, which is known for its rigid construction, precision, and advanced multi-process capabilities. The machine offers axis travels of approximately 3,400 mm (X), 2,800 mm (Y), and 1,600 mm (Z), providing a large working envelope suitable for industries such as aerospace, energy, automotive, and heavy engineering. It can accommodate workpiece weights of up to 12,000 kg (or lower in FD configuration), ensuring stable machining of heavy-duty parts.

A key highlight of the DMC 340 U (FD) is its FD (mill-turn) capability. Equipped with a DirectDrive rotary table, the machine enables both high-precision turning and full 5-axis simultaneous milling in one setup. This eliminates the need for multiple machines, reduces handling time, and significantly improves overall productivity. In advanced configurations, grinding operations can also be integrated, allowing true multi-process machining within a single platform.

The machine’s portal design ensures exceptional rigidity and thermal stability. Features such as water-cooled feed drives, temperature-controlled guideways, and active spindle growth compensation help maintain consistent accuracy even during long machining cycles. Positioning accuracy remains in the micron range, making the machine suitable for high-precision applications.

From a performance standpoint, the DMC 340 U (FD) offers powerful spindle options, including motor spindles for high-speed machining and gear spindles for high-torque operations. Feed rates of up to 60 m/min and large tool magazine capacities (often exceeding 200 tools) support efficient multi-stage machining. Equipped with advanced CNC systems such as Siemens or HEIDENHAIN and CELOS integration, the machine enables real-time monitoring, simulation, and process optimization, making it a premium solution for large-part manufacturing.

WHY BUY USED DMG MORI DMC 340 U (FD)

Buying a used DMG MORI DMC 340 U (FD) is a strategic decision for manufacturers who require large-scale 5-axis machining with integrated mill-turn capability at a lower capital cost. One of the biggest advantages is depreciation. Machines in this category are highly expensive when new due to their size, complexity, and advanced engineering, but their value decreases significantly after initial use. This allows buyers to access high-end machining technology at a more affordable price.

Another key advantage is cutting time efficiency relative to cost. The DMC 340 U (FD) is designed for complete machining, combining milling, turning, and even grinding in one setup. Even used machines retain strong performance due to their rigid portal structure and high-quality components. This reduces setup changes, minimizes downtime, and improves cycle efficiency, ultimately lowering cost per part and increasing productivity.

Durability is a major strength of this machine. Its heavy-duty construction, advanced cooling systems, and high-quality guideways are built for long-term operation under demanding conditions. Machines with moderate cutting time (typically under 15,000–25,000 spindle hours) generally still offer excellent accuracy and reliability. Even machines with higher cutting hours can remain productive if properly maintained, although servicing of spindles, rotary tables, and drive systems may be required over time.

Another important benefit is process integration. Many used machines come equipped with FD tables, large tool magazines, probing systems, and automation-ready configurations. These features provide immediate operational value and reduce additional investment requirements.

Cutting time (spindle hours) is more important than manufacturing year when evaluating a machine. A lower-hour older machine may outperform a newer high-hour unit. For manufacturers focused on ROI, flexibility, and efficiency, a used DMC 340 U (FD) offers excellent value and advanced machining capability.

HOW MUCH DOES A USED DMG MORI DMC 340 U (FD) COST?

The cost of a used DMG MORI DMC 340 U (FD) varies significantly depending on manufacturing year, configuration, machine condition, and most importantly, cutting time (spindle hours). As a large 5-axis portal machine with mill-turn capability, it falls into the premium price segment, and even used machines require a substantial investment. Machines with low spindle hours and strong maintenance records command higher prices, while heavily used machines are more affordable due to wear on critical components.

For machines built before 2000, direct DMC 340 U (FD) models are not available, but comparable large portal or gantry machining centers typically range from $150,000 to $400,000. These machines often have very high cutting hours and older control systems, making them suitable for basic large-part machining rather than advanced multi-process applications.

Machines from the 2000–2010 period generally range from $400,000 to $900,000 depending on condition and usage. Units with moderate cutting time (around 20,000–40,000 spindle hours) are considered good value for heavy-duty machining environments where large work envelopes are required.

For actual DMC 340 U (FD) machines manufactured between 2010 and 2025, prices typically range from $900,000 to $2,200,000 or more depending on configuration. Machines with low cutting hours (under 10,000–15,000 hours), FD turning capability, advanced spindle options, and large tool magazine capacities command the highest prices.

Cutting time is one of the most critical valuation factors. A newer machine with excessive spindle hours may be priced similarly to an older machine with lower usage. Therefore, buyers should prioritize machine condition, service history, and real machining performance rather than relying solely on manufacturing year to ensure a cost-effective and high-value investment.
