USED DMG MORI DMU 340 P (FD)

The DMG MORI DMU 340 P (FD) is a large-scale, high-performance 5-axis portal machining center designed for complete machining of heavy and complex components in a single setup. It is part of the DMU Portal series, known for its rigid bridge-type construction and ability to deliver high precision and dynamic performance for industries such as aerospace, energy, automotive, and mold & die. The machine offers axis travels of approximately 3,400 mm (X), 3,400 mm (Y), and up to 2,000 mm (Z), providing a large working envelope for oversized components. It can handle workpieces weighing up to 20,000 kg (around 7,000 kg in FD configuration), making it suitable for demanding large-part machining applications.

A key highlight of the DMU 340 P (FD) is its FD (mill-turn) capability. Equipped with a DirectDrive rotary table, the machine enables both milling and turning in a single setup, significantly reducing setup time and improving productivity. It also supports grinding integration, allowing complete multi-process machining within one platform.

The machine’s portal design ensures excellent rigidity and thermal stability. Features such as water-cooled feed drives, cooled linear guideways, and active spindle growth control help maintain consistent positioning accuracy even during long machining cycles. Accuracy can reach as low as 12–15 microns depending on configuration, making it suitable for high-precision applications.

From a performance perspective, the DMU 340 P (FD) offers powerful spindle options, including motor spindles up to 1,000 Nm and gear spindles up to 1,800 Nm. Feed speeds of up to 40 m/min and high feed forces enable both heavy roughing and high-speed finishing. Large tool magazine capacities (up to 243 tools) and advanced control systems such as Siemens and HEIDENHAIN with CELOS integration ensure efficient programming, monitoring, and process optimization. Overall, it is a premium solution for large, complex, and high-value component manufacturing.

WHY BUY USED DMG MORI DMU 340 P (FD)

Buying a used DMG MORI DMU 340 P (FD) is a strategic investment for manufacturers requiring large-scale 5-axis machining combined with mill-turn capability at a reduced capital cost. One of the biggest advantages is depreciation. Machines in this category are extremely expensive when new due to their size, portal construction, and multi-process integration, but their value drops significantly after initial use. This allows buyers to access advanced machining technology at a fraction of the original investment.

Another major advantage is cutting time efficiency relative to cost. The DMU 340 P (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 structure and high-quality components. This reduces setup changes, minimizes idle time, and improves overall cycle efficiency, leading to lower cost per part and higher productivity.

Durability is a key strength of this machine. Its heavy-duty portal construction, thermosymmetrical design, and advanced cooling systems ensure long-term stability under demanding machining conditions. Machines with moderate cutting time (typically under 15,000–30,000 spindle hours) generally still offer excellent accuracy and reliability. Even machines with higher cutting hours can remain productive, 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 add immediate operational value and reduce the need for additional investment.

Cutting time (spindle hours) is more important than manufacturing year when evaluating a machine. A lower-hour older machine may perform better than a newer machine with heavy usage. For manufacturers focused on ROI, flexibility, and complete machining capability, a used DMU 340 P (FD) offers excellent value and performance.

HOW MUCH DOES A USED DMG MORI DMU 340 P (FD) COST?

The cost of a used DMG MORI DMU 340 P (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 represent 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 DMU 340 P (FD) models are not available, but comparable large portal or gantry machining centers typically range from $120,000 to $350,000. 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 $350,000 to $800,000 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 DMU 340 P (FD) machines manufactured between 2010 and 2025, prices typically range from $800,000 to $2,000,000 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 high-value and cost-effective investment.
