USED DMG MORI DMF 300-11 (FD) LINEAR

The DMG MORI DMF 300|11 (FD, linear) is a high-precision 5-axis gantry-style machining center designed for long and large workpieces requiring exceptional accuracy and surface quality. Built on a monolithic moving-column design with linear drive technology, it offers high dynamic performance, reduced friction, and superior positioning accuracy, making it ideal for aerospace, automotive, die & mold, and large structural component manufacturing.

The machine features an extended working envelope with approximately 3,000 mm in X, 1,100 mm in Y, and 900 mm in Z travel, allowing machining of large and elongated components in a single setup. The rigid machine bed and gantry-style construction ensure excellent stability even during high-speed machining operations. Linear motors in key axes enable high acceleration and rapid traverse speeds, significantly improving productivity and reducing cycle times.

A defining feature of the DMF 300|11 (FD, linear) is its FD (mill-turn) capability, which integrates turning operations into the machining process through a DirectDrive rotary table. This allows combined milling and turning in a single setup, eliminating repositioning and improving geometric accuracy. It is particularly beneficial for complex aerospace and mold components where multiple operations are required.

The machine is typically equipped with high-speed spindles capable of up to 18,000 RPM or more, with strong torque output for both roughing and finishing operations. Tool magazine capacities are large, often exceeding 60 tools, supporting complex multi-process machining without interruption.

Thermal stability is a critical aspect of the machine design, with cooled linear drives, temperature-controlled structural components, and advanced compensation systems ensuring consistent micron-level accuracy during long machining cycles. CNC control systems such as Siemens SINUMERIK 840D sl or Heidenhain TNC platforms provide advanced programming, simulation, and process monitoring capabilities.

Overall, the DMF 300|11 (FD, linear) is a highly dynamic, precise, and versatile machining solution designed for long-part machining with integrated mill-turn functionality and superior surface finish requirements.

WHY BUY USED DMG MORI DMF 300-11 (FD) LINEAR

Buying a used DMG MORI DMF 300|11 (FD, linear) is a smart choice for manufacturers requiring large-format 5-axis machining with high precision and speed at a significantly reduced cost compared to new equipment. Its robust gantry-style construction and linear drive technology ensure long-term performance, even in machines with moderate usage.

One of the main advantages is cost efficiency. New DMF linear machines are positioned in the premium segment due to their advanced linear drive systems, large working envelope, and integrated mill-turn functionality. In the used market, buyers can access the same advanced technology at a much lower investment, improving return on investment while maintaining high machining capability.

Another key benefit is faster availability. New machines often come with long lead times due to customization and manufacturing schedules, whereas used machines are typically available for quicker installation. This is especially beneficial for companies needing immediate production expansion.

The DMF 300|11 (FD, linear) is designed for durability and precision. Machines with cutting hours in the range of 5,000 to 20,000 hours can still deliver excellent performance when properly maintained. Even higher-hour machines remain viable due to the reduced mechanical wear associated with linear drive systems compared to traditional ball screw designs.

From a productivity perspective, the machine enables complete machining of long and complex parts in a single setup. The FD capability further enhances efficiency by combining milling and turning operations, reducing setup time and increasing throughput.

Depreciation is another key advantage. High-end CNC machines lose a significant portion of their value in the early years, meaning used buyers can avoid this depreciation while still benefiting from advanced machining technology. This makes the DMF 300|11 (FD, linear) a cost-effective and low-risk investment for precision manufacturing operations.

HOW MUCH DOES A USED DMG MORI DMF 300-11 (FD) LINEAR COST?

The cost of a used DMG MORI DMF 300|11 (FD, linear) depends on several factors including year of manufacture, configuration (FD mill-turn option), spindle condition, control system, and especially cutting time (spindle hours). As a large-format linear-drive machining center, it commands strong demand in the used CNC market.

For older machines (2008–2012 range), prices typically range between $180,000 and $300,000, depending on condition and usage. Machines with higher cutting hours (25,000–45,000+ hours) are generally priced lower due to expected maintenance requirements such as spindle servicing or alignment checks.

For mid-generation machines (2012–2018 range), pricing usually falls between $300,000 and $500,000. These machines often include improved control systems, better thermal compensation, and upgraded spindle options. Units with lower spindle hours (under 20,000 hours) and well-maintained FD functionality are positioned at the higher end.

For recent models (2018–2025 or lightly used machines), prices can range from $500,000 to $800,000+, especially when equipped with advanced CNC controls (Siemens SINUMERIK ONE or Heidenhain TNC7), automation integration, and high-capacity tool magazines. These machines retain strong resale value due to their precision, speed, and versatility.

Cutting time is one of the most critical pricing factors. Lower-hour machines typically require minimal refurbishment and deliver near-new performance, while higher-hour machines may require spindle rebuilding, calibration, or maintenance of linear drive systems.

In conclusion, the DMF 300|11 (FD, linear) sits in the premium segment of the used CNC market. With proper evaluation of machine condition, configuration, and usage history, it offers excellent long-term value for manufacturers requiring high-precision, large-format 5-axis machining with integrated mill-turn capability.
