USED DMG MORI CVG 9

The DMG MORI CVG 9 is a high-performance CNC vertical multi-process grinding machine designed for precision machining of medium to large components with complex geometries. As part of the CVG series developed by Taiyo Koki under DMG MORI, it integrates internal (ID), external (OD), and face grinding into a single setup, significantly improving productivity and accuracy. This machine is widely used in industries such as aerospace, automotive, energy, and heavy engineering, where large components require high precision and process consolidation.

The CVG 9 offers a swing diameter of 950 mm and a maximum grinding diameter of 900 mm, along with a maximum workpiece height of 700 mm and grinding length up to 600 mm. These specifications make it suitable for handling larger components compared to models like the CVG 6, while still maintaining a compact vertical footprint. It can accommodate workpieces weighing up to approximately 2,500 kg, highlighting its capability for heavy-duty applications. The work spindle operates at speeds up to 250 rpm, while the grinding spindle reaches up to 9,000 rpm, ensuring stable and efficient material removal.

A key strength of the CVG 9 is its vertical design, which enhances rigidity and minimizes workpiece deflection, particularly when machining heavy parts. The machine features a turret-type wheelhead with indexing positions and optional continuous B-axis control, allowing precise angular adjustments for complex grinding operations. Additionally, the optional C-axis with direct drive enables high-precision profile grinding for applications such as cams and curvic couplings.

The CVG 9 is also designed for productivity, with features such as a 2-pallet automatic pallet changer (APC) that reduces non-cutting time and enables unattended operation. Other enhancements include an automatic tool changer (ATC), touch probes for in-process measurement, and linear scale feedback systems for improved accuracy. Overall, the CVG 9 is a powerful and versatile grinding solution for manufacturers requiring high precision, automation, and efficiency in medium-to-large component production.

WHY BUY USED DMG MORI CVG 9

Buying a used DMG MORI CVG 9 is a highly practical choice for manufacturers looking to acquire advanced multi-process grinding capability without the high capital cost of a new machine. One of the most significant advantages is cost efficiency. New machines in this category are expensive due to their precision engineering, automation capabilities, and heavy-duty construction, but used machines often retain the same functional performance at a significantly reduced price.

Another key benefit is durability. DMG MORI machines are known for their robust design and long service life, and the CVG 9 is built to handle heavy workpieces while maintaining precision. Because grinding processes involve lower cutting forces than milling or turning, structural wear is minimized. This allows even older machines to remain operational and accurate when properly maintained.

Cutting time, or machine hours, is one of the most important factors when evaluating a used CVG 9. Machines with lower grinding hours typically offer better spindle condition, improved axis accuracy, and longer service life. However, even machines with higher usage can still be a strong investment if they have undergone refurbishment, such as spindle rebuilding, encoder replacement, or CNC upgrades. In many cases, a well-maintained high-hour machine can outperform a poorly maintained low-hour one.

Another advantage is faster availability. Used machines can often be delivered and installed much more quickly than new equipment, which may involve long lead times. Many used CVG 9 machines also come with automation features such as pallet changers, tooling, and measurement systems, which adds immediate value and reduces additional setup costs.

Finally, depreciation works in favor of the buyer. High-end CNC grinding machines lose value over time while retaining their precision capabilities. This makes a used CVG 9 an excellent option for companies looking to expand capacity, improve efficiency, or enter high-precision grinding without a major upfront investment.

HOW MUCH DOES A USED DMG MORI CVG 9 COST?

The cost of a used DMG MORI CVG 9 varies significantly depending on factors such as manufacturing year, machine condition, cutting hours, automation features, and included tooling. As a large-capacity vertical multi-process grinding machine, it typically falls into the premium segment of the used CNC grinding market.

For machines manufactured before 2000, prices generally range from $50,000 to $120,000. These machines often have high 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 typically range between $110,000 and $220,000. These units often include improved CNC controls and may feature early automation options such as pallet changers. Cutting time becomes a key pricing factor in this category—machines with lower hours or recent refurbishments tend to command higher prices due to better reliability and performance.

For newer machines manufactured between 2010 and 2025, prices can range from $250,000 to $500,000 or more, especially for units equipped with advanced features such as automatic pallet changers, in-process measurement systems, and low cutting hours. These machines are ideal for high-precision, high-volume production environments where uptime and automation are critical.

Cutting time remains 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 consider costs such as installation, tooling, and potential retrofits. Overall, the CVG 9 represents a high-value investment, offering large capacity, advanced automation, and long-term reliability in demanding industrial applications.
