USED DMG MORI DMU 340 GANTRY

The DMG MORI DMU 340 Gantry is a large-format, high-performance 5-axis machining center designed for machining extremely large and heavy components with exceptional precision and dynamics. It is part of DMG MORI’s Gantry series, which focuses on combining massive work envelopes with advanced machining capabilities for industries such as aerospace, energy, automotive, and heavy engineering. The machine offers axis travels of approximately 6,000 mm (X), 2,800 mm (Y), and 1,500 mm (Z), enabling the machining of very large components in a single setup. It supports workpiece weights of up to 30,000 kg, making it suitable for structural parts, molds, and large mechanical assemblies.

A key strength of the DMU 340 Gantry is its rigid gantry design with a thermosymmetrical machine structure, which ensures high stability and consistent accuracy even during long machining cycles. The vertically moving cross beam with hydraulic weight compensation enhances rigidity while maintaining dynamic performance. Advanced cooling systems, including water-cooled feed drives and cooled linear guideways, help minimize thermal deformation and ensure long-term precision.

The machine is equipped with powerful spindle options, including motor spindles and gear spindles with torque up to 1,800 Nm, allowing both heavy roughing and high-speed finishing. Feed speeds of up to 40,000 mm/min and high feed forces enable efficient material removal while maintaining surface quality.

From a productivity standpoint, the DMU 340 Gantry is designed to maximize cutting time and minimize downtime. It supports large tool magazines with up to 243 tools, advanced automation integration, and modern control systems such as HEIDENHAIN and CELOS. These features enable efficient programming, real-time monitoring, and seamless integration into digital manufacturing environments. Overall, the DMU 340 Gantry is a premium solution for manufacturers requiring large-scale, high-precision machining with advanced automation capabilities.

WHY BUY USED DMG MORI DMU 340 GANTRY

Buying a used DMG MORI DMU 340 Gantry is a strategic decision for manufacturers needing large-capacity 5-axis machining without the extremely high capital investment required for a new machine. One of the biggest advantages is depreciation. Machines in this category are among the most expensive CNC systems due to their size, complexity, and advanced engineering, but their value decreases significantly after initial use. This allows buyers to access top-tier gantry machining technology at a substantially lower cost.

Another important factor is cutting time efficiency relative to investment. The DMU 340 Gantry is designed for heavy-duty machining and complex geometries, and even used machines retain strong performance due to their rigid structure and high-quality components. For industries such as aerospace or energy, where machining cycles are long and precision is critical, a well-maintained used machine can deliver performance very close to a new unit. This results in lower cost per part and improved return on investment.

Durability is a major strength of the DMU 340 Gantry. Its heavy-duty construction, thermally stable design, and advanced guideway systems are built for long-term operation under demanding conditions. Machines with moderate cutting time (typically under 15,000–30,000 spindle hours) generally still offer excellent performance and accuracy. Even machines with higher cutting hours can remain productive, although they may require servicing of key components such as spindles, drives, and guideways.

Additionally, used machines often include valuable extras such as large tool magazines, advanced spindle heads, or automation systems. Evaluating a machine based on cutting time rather than manufacturing year is critical, as spindle hours provide a more accurate indication of wear. For manufacturers requiring large-scale machining capabilities, a used DMU 340 Gantry offers exceptional value, performance, and capacity.

HOW MUCH DOES A USED DMG MORI DMU 340 GANTRY COST?

The cost of a used DMG MORI DMU 340 Gantry varies significantly depending on manufacturing year, configuration, machine condition, and most importantly, cutting time (spindle hours). As a large 5-axis gantry machine, it falls into the highest price segment of CNC equipment, and pricing reflects its size, capability, and advanced technology. Machines with low spindle hours and strong maintenance history command premium prices, while heavily used machines are more affordable due to wear on critical systems.

For machines built before 2000, direct DMU 340 Gantry models are not available, but comparable large gantry or bridge-type machining centers typically range from $100,000 to $300,000. These machines often have very high cutting hours and older control systems, making them suitable for basic large-part machining rather than high-precision applications.

Machines from the 2000–2010 period generally range from $300,000 to $800,000 depending on condition and usage. Units with moderate cutting time (around 25,000–40,000 spindle hours) are considered good value for heavy machining applications. These machines are commonly used in industries requiring large work envelopes without investing in new equipment.

For actual DMU 340 Gantry machines manufactured between 2010 and 2025, prices typically range from $800,000 to $2,000,000 or more depending on configuration, spindle type, and automation level. Machines with low cutting hours (under 10,000–15,000 hours), advanced 5-axis heads, and large tool magazine capacities are priced at the higher end.

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