USED DMG MORI CVG 13

The DMG MORI CVG 13 is a large-capacity CNC vertical multi-process grinding machine designed for high-precision machining of heavy and oversized components. As the largest model in the CVG series developed by Taiyo Koki under DMG MORI, it combines advanced grinding capabilities with automation and process integration, making it ideal for industries such as aerospace, energy, automotive, and heavy engineering. The machine is particularly suited for large components like turbine casings, bearing housings, and gear assemblies that require tight tolerances and high surface quality.

The CVG 13 features a swing diameter of 1,350 mm and a maximum grinding diameter of 1,300 mm, with a maximum workpiece height of 700 mm and grinding length up to 600 mm. It is capable of handling extremely heavy workpieces, with a maximum load capacity of up to 3,000 kg, making it one of the most powerful machines in its category. The work spindle operates at speeds up to 100 rpm, while the grinding spindle reaches up to 9,000 rpm, ensuring stable and efficient material removal even on large components.

A key advantage of the CVG 13 is its vertical design, which enhances rigidity and reduces workpiece deflection, especially when machining heavy parts. The machine is equipped with a turret-type wheelhead with multiple indexing positions, along with optional continuous B-axis control for precise angular adjustments. Additionally, the optional C-axis with direct drive enables profile grinding of complex shapes such as cams and curvic couplings with high precision.

The CVG 13 also supports advanced automation features, including a 2-pallet automatic pallet changer (APC), which reduces non-cutting time and allows for extended unattended operation. Other features such as a 6-tool automatic tool changer (ATC), touch probes for in-process measurement, and linear scale feedback systems further enhance productivity and accuracy. Overall, the CVG 13 is a high-performance grinding solution designed for large-scale precision applications requiring reliability, flexibility, and process efficiency.

WHY BUY USED DMG MORI CVG 13

Buying a used DMG MORI CVG 13 is a highly strategic decision for manufacturers requiring large-capacity precision grinding without the substantial capital investment of a new machine. One of the most significant advantages is cost efficiency. New machines of this size and capability can be extremely expensive due to their advanced engineering, automation features, and heavy-duty construction, while used machines often retain similar performance at a much lower price.

Another important factor is durability. DMG MORI machines are known for their robust construction and long service life, and the CVG 13 is specifically designed to handle heavy workpieces while maintaining precision. Because grinding processes involve relatively low cutting forces compared to milling or turning, structural wear is minimized. This allows even older machines to maintain acceptable accuracy and reliability when properly maintained.

Cutting time, or machine hours, plays a crucial role in determining the value of a used CVG 13. 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 viable investment if they have undergone refurbishment, such as spindle rebuilding, replacement of feedback systems, or CNC control upgrades. In many cases, maintenance history is more important than the machine’s manufacturing year.

Another advantage is immediate availability. Used machines can often be sourced and installed much faster than new equipment, which may involve long lead times. Many used CVG 13 units also come equipped with automation features such as pallet changers, tooling, and measurement systems, which adds immediate value and reduces additional setup costs.

Finally, depreciation benefits the buyer. High-end CNC grinding machines lose a significant portion of their value over time while retaining their functional capabilities. This makes a used CVG 13 an excellent option for companies looking to expand capacity, handle large-part grinding, or improve productivity without a major upfront investment.

HOW MUCH DOES A USED DMG MORI CVG 13 COST?

The cost of a used DMG MORI CVG 13 varies significantly depending on factors such as manufacturing year, machine condition, cutting hours, automation features, and included tooling. As one of the largest and most advanced vertical grinding machines in the CVG series, it typically falls into the premium segment of the used CNC grinding market.

For machines manufactured before 2000, prices generally range from $60,000 to $150,000. 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 $140,000 and $300,000. These units often include improved CNC controls and may feature early automation options such as pallet changers. Cutting time becomes a key pricing factor—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 $350,000 to $700,000 or more, especially for units equipped with advanced features such as automatic pallet changers, in-process measurement systems, and low cutting hours. In fact, some newer vertical grinding machines in this category have been reported in the market at close to $700,000 depending on configuration and condition, indicating the premium nature of this equipment.

Cutting time remains one of the most critical 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 13 represents a high-value investment, offering unmatched capacity, precision, and long-term reliability in demanding industrial applications.
