USED DMG MORI IGH-10NT

The DMG MORI IGH-10NT is a high-capacity CNC internal grinding machine designed for precision grinding of longer and heavier components while maintaining exceptional accuracy and surface finish. As the largest model in the IGH horizontal grinding series, it is widely used in industries such as aerospace, automotive, spindle manufacturing, and heavy precision engineering, where long shafts, bearing components, and internal geometries must meet stringent tolerance requirements.

The IGH-10NT features a swing diameter of 300 mm, a maximum grinding diameter of 275 mm, and a grinding length of up to 600 mm. It can accommodate workpieces up to 1,000 mm in length, making it ideal for larger and longer parts compared to smaller IGH models. The work spindle operates at speeds up to 500 rpm, and the machine has a substantial weight of approximately 9,500 kg, ensuring high rigidity and stability during grinding operations.

One of the key features of the IGH-10NT is its turret-type wheelhead equipped with both internal and external grinding spindles. This configuration allows ID, OD, face, and taper grinding to be performed in a single clamping, significantly improving efficiency and accuracy by eliminating repositioning errors. The machine also includes an NC-controlled swivel table capable of ultra-fine angular adjustments down to 0.0001°, enabling precise taper grinding and complex geometries.

The IGH-10NT is typically equipped with a FANUC CNC control system, ensuring high programmability, repeatability, and compatibility with automation features such as NC loaders and automatic measurement systems. Its robust construction minimizes vibration, which is critical when grinding long components where deflection can impact accuracy.

Overall, the IGH-10NT is a powerful and versatile internal grinding solution, specifically designed for manufacturers who require high-precision machining of longer workpieces with consistent quality and reduced setup time.

WHY BUY USED DMG MORI IGH-10NT

Buying a used DMG MORI IGH-10NT is a highly practical decision for manufacturers looking to access large-capacity internal grinding capabilities without the high investment required for a new machine. One of the biggest advantages is cost efficiency. New CNC grinding machines of this size and precision level can be extremely expensive, but used machines often retain their core functionality and accuracy while being available at a significantly lower price.

Another major benefit is the machine’s durability. DMG MORI machines are known for their robust construction and long service life, and the IGH-10NT is no exception. Its heavy structure and rigid design ensure long-term stability and accuracy, even after years of operation. Since grinding involves relatively low cutting forces compared to milling, structural wear is minimized, allowing older machines to continue delivering reliable performance if properly maintained.

Cutting time, or machine hours, is a critical factor when evaluating a used IGH-10NT. Machines with lower grinding hours typically offer better spindle condition, improved axis precision, and longer service life. However, even higher-hour machines can still be a worthwhile investment if they have undergone refurbishment, such as spindle rebuilding, encoder replacement, or CNC control upgrades. In many cases, maintenance history is more important than the machine’s manufacturing year.

Another advantage is faster availability. Used machines can often be sourced and installed much more quickly than new equipment, which may have long lead times. Additionally, many used IGH-10NT machines come with tooling, fixtures, or automation features already installed, reducing setup costs and improving productivity from day one.

Finally, depreciation works strongly in favor of the buyer. High-end CNC grinding machines lose value over time, but their precision capabilities remain intact. This makes a used IGH-10NT an excellent choice for companies expanding capacity or entering high-precision grinding without committing to a large capital investment.

HOW MUCH DOES A USED DMG MORI IGH-10NT COST?

The cost of a used DMG MORI IGH-10NT varies significantly depending on factors such as manufacturing year, machine condition, cutting hours, and included tooling or upgrades. As the largest and most capable model in the IGH series, it generally commands higher prices than smaller models due to its extended capacity and ability to handle long workpieces.

For machines manufactured before 2000, prices typically range between $35,000 and $80,000. These machines often have higher cutting hours and may require refurbishment, such as spindle rebuilding, replacement of feedback systems, or CNC control upgrades. However, they can still be suitable for less demanding applications or lower production volumes if properly maintained.

Machines from the 2000–2010 period generally fall within the $70,000 to $140,000 range. These units often feature improved CNC controls and enhanced automation compatibility. Cutting time becomes a key pricing factor in this category, with lower-hour machines or recently refurbished units commanding higher prices due to better reliability and accuracy.

For newer machines manufactured between 2010 and 2025, prices can range from $130,000 to $250,000 or more. These machines typically have lower cutting hours, better accuracy retention, and may include advanced features such as automatic measurement systems and loading automation. They are ideal for high-precision, high-volume production environments where consistency and uptime are critical.

Cutting time is one of the most important determinants of price. A low-hour machine with a strong maintenance record will command a premium, while a high-hour machine may require additional investment in repairs or calibration. Buyers should also factor in costs such as installation, tooling, and potential retrofits. Overall, the IGH-10NT represents a high-value investment in precision grinding, with pricing reflecting its size, capability, and long-term reliability.
