USED DMG MORI VERTICAL MATE 125

The DMG MORI Vertical Mate 125 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 Vertical Mate series, it is specifically engineered for industries such as aerospace, energy, automotive, and heavy engineering, where large workpieces like bearing housings, turbine components, and gear assemblies require tight tolerances and superior surface finishes.

The machine offers a swing diameter of 1,250 mm and a maximum grinding diameter of 1,200 mm, with a maximum workpiece height of 600 mm and grinding length of up to 500 mm. These dimensions make it suitable for handling large-diameter components that smaller grinding machines cannot accommodate. Additionally, the machine can support heavy workpieces up to approximately 2,500 kg, highlighting its capability in heavy-duty precision grinding applications.

A key feature of the Vertical Mate 125 is its multi-process functionality, allowing internal diameter (ID), external diameter (OD), and face grinding in a single setup. This significantly reduces setup time and improves overall accuracy by eliminating repositioning errors. The machine is equipped with a 2-position turret and an automatic tool changer (ATC) with up to six tools, enabling flexible machining of complex parts.

The grinding spindle reaches speeds of up to 9,000 rpm, while the work spindle operates up to 100 rpm, ensuring stable and efficient machining of large components. The machine also incorporates advanced features such as scale feedback systems, optional touch probes for in-process measurement, and high-precision dressing systems. Accuracy is a major highlight, with roundness and surface finish reaching approximately 2.0 µm and Ra 0.2 µm respectively.

Overall, the Vertical Mate 125 is a powerful and versatile grinding solution, combining large work capacity, multi-process capability, and high precision in a single platform, making it ideal for manufacturers handling complex, heavy-duty components.

WHY BUY USED DMG MORI VERTICAL MATE 125

Buying a used DMG MORI Vertical Mate 125 is a highly practical decision for manufacturers requiring large-capacity precision grinding without the significant capital investment of a new machine. One of the primary advantages is cost savings. New machines of this size and capability can be extremely expensive due to their heavy-duty construction and advanced grinding technology, while used machines often deliver comparable performance at a much lower price.

Another major benefit is durability. The Vertical Mate 125 is built with a rigid structure designed to support heavy workpieces and maintain stability during grinding. Because grinding operations involve relatively low cutting forces compared to milling or turning, structural wear is minimized. This allows even older machines to retain acceptable accuracy and performance when properly maintained, making them a reliable long-term investment.

Cutting time, or machine hours, plays a crucial role in evaluating a used machine. 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 valuable if they have undergone refurbishment, such as spindle rebuilding, replacement of scale feedback systems, or upgrades to CNC controls. In many cases, maintenance history is more important than the manufacturing year itself.

Another advantage is faster availability. Used machines can often be sourced and installed much more quickly than new equipment, which may involve long lead times. Many used Vertical Mate 125 units also come with tooling, fixtures, or optional measurement systems, reducing additional setup costs and improving operational readiness.

Finally, depreciation works in favor of the buyer. High-end CNC grinding machines lose a significant portion of their value over time while retaining their core functionality. This makes a used Vertical Mate 125 an excellent option for companies looking to expand capacity, enter large-part grinding, or improve production efficiency without a major upfront investment.

HOW MUCH DOES A USED DMG MORI VERTICAL MATE 125 COST?

The cost of a used DMG MORI Vertical Mate 125 varies widely depending on factors such as manufacturing year, machine condition, cutting hours, included tooling, and any retrofits or upgrades. As a large-capacity, high-precision grinding machine, it typically falls into the premium segment of the used CNC 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, control upgrades, or replacement of measurement systems. 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 $100,000 and $220,000. These units often include improved CNC controls and better automation compatibility. Cutting time becomes a major pricing factor in this category—machines with lower hours or recent refurbishments tend to command higher prices due to better accuracy and reliability.

For newer machines manufactured between 2010 and 2025, prices can range from $250,000 to $500,000 or more, especially for machines with low cutting hours, advanced automation features, and in-process measurement systems. These machines are ideal for high-precision and high-volume production environments where uptime and consistency 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 consider costs such as installation, tooling, and potential retrofits. Overall, the Vertical Mate 125 represents a high-value investment, offering large capacity, precision, and long-term reliability in demanding industrial applications.
