USED DMG MORI IGV-1N

The DMG MORI IGV-1N is a compact, high-precision CNC vertical internal grinding machine designed for small components requiring tight tolerances and superior surface finishes. Developed by Taiyo Koki under DMG MORI, the IGV series is known for its rigidity, thermal stability, and ability to perform high-speed internal grinding with excellent accuracy. The IGV-1N is widely used in industries such as automotive, bearing manufacturing, precision engineering, and tooling, where small parts demand consistent quality and high repeatability.

The machine features a swing diameter of approximately 200 mm and a maximum grinding diameter of around 150 mm, with a maximum workpiece height of about 150 mm. It is designed to handle smaller workpieces, typically weighing up to 50–80 kg, making it ideal for precision internal grinding applications. The work spindle operates at speeds up to 1,500 rpm, while the internal grinding spindle can reach very high speeds of up to 40,000 rpm, enabling fine surface finishes and efficient material removal even on small diameters.

A key advantage of the IGV-1N is its vertical design, which improves rigidity and minimizes workpiece deflection during grinding. This configuration also enhances chip evacuation and coolant flow, contributing to stable machining conditions. The machine is equipped with a high-speed grinding spindle and precision linear guideways, ensuring smooth axis movement and consistent accuracy.

The IGV-1N also incorporates features such as automatic dressing systems, optional in-process measurement, and user-friendly CNC controls for efficient operation. Its compact footprint allows easy integration into production lines, while its high-speed capability makes it suitable for high-volume manufacturing of precision parts such as bearing races, bushings, and small cylindrical components.

Overall, the IGV-1N is a reliable and efficient internal grinding solution, offering high precision, compact design, and strong performance for small-part manufacturing environments.

WHY BUY USED DMG MORI IGV-1N

Buying a used DMG MORI IGV-1N is a practical and cost-effective option for manufacturers seeking high-precision internal grinding capability without the expense of a new machine. One of the main advantages is cost savings. New internal grinding machines with high-speed spindles and advanced controls can be expensive, but used units offer similar functionality at a significantly reduced price, making them accessible for smaller operations or expanding production lines.

Another important benefit is durability. Machines built by DMG MORI are known for their quality construction and long service life. The IGV-1N, with its rigid vertical design and precision components, is capable of maintaining accuracy over time. Because internal grinding involves relatively low cutting forces, structural wear is limited, allowing older machines to remain effective if they have been properly maintained.

Cutting time, or machine hours, is a critical factor when evaluating a used IGV-1N. Machines with lower grinding hours typically offer better spindle condition, improved axis precision, and longer remaining life. However, machines with higher usage can still be a good investment if they have undergone refurbishment, such as spindle rebuilding, replacement of bearings, or updates to the CNC control system. Maintenance history often provides a better indication of machine condition than age alone.

Another advantage is quick availability. Used machines can often be sourced and installed much faster than new ones, which may have long lead times. Many used IGV-1N machines also come with tooling, fixtures, or measurement systems, reducing additional setup costs and allowing faster production startup.

Depreciation further benefits the buyer. High-end grinding machines lose value over time while retaining their performance capabilities. This makes a used IGV-1N an excellent option for companies looking to improve precision or increase capacity without a major capital investment.

HOW MUCH DOES A USED DMG MORI IGV-1N COST?

The cost of a used DMG MORI IGV-1N varies depending on factors such as manufacturing year, machine condition, cutting hours, and included tooling or upgrades. As a compact internal grinding machine, it generally falls into the lower-to-mid price range of the used CNC grinding market, making it accessible compared to larger multi-process machines.

For machines manufactured before 2000, prices typically range from $15,000 to $40,000. These machines often have high cutting hours and may require refurbishment, such as spindle rebuilding, replacement of bearings, or upgrades to CNC controls. However, they can still be suitable for less demanding applications or lower production volumes if properly maintained.

Machines from the 2000–2010 period generally range between $35,000 and $80,000. These units often include improved CNC systems and better spindle technology. Cutting time becomes a key pricing factor—machines with lower hours or recent maintenance tend to command higher prices due to better reliability and accuracy.

For newer machines manufactured between 2010 and 2025, prices can range from $80,000 to $160,000 or more, particularly for units with low cutting hours, upgraded controls, and additional features such as in-process measurement systems or automation integration. These machines are ideal for high-precision and high-volume production environments.

Cutting time remains one of the most important factors influencing 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 consider costs such as tooling, installation, and potential retrofits. Overall, the IGV-1N offers strong value in the used market, providing reliable high-speed internal grinding capability at a relatively affordable cost.
