USED DMG MORI CTX 350 4A

The DMG MORI CTX 350 4A is a high-productivity CNC turning center designed for complete machining of complex parts in a compact footprint. Unlike the standard CTX 350, the 4A version is built with dual turrets and dual spindles, enabling simultaneous machining and significantly improving cycle times. It is widely used in industries such as automotive, medical, precision engineering, and subcontract manufacturing where efficiency and multi-operation capability are critical.

The machine is capable of handling workpieces up to approximately 320 mm in diameter and 530 mm in length, with a bar capacity of up to 65 mm. A key advantage of the CTX 350 4A is its ability to perform full 6-sided machining in a single setup, thanks to its synchronized main and counter spindle configuration.

One of the most defining features is the dual-turret system, which allows both turrets to operate on either spindle independently or simultaneously. This dramatically increases cutting time efficiency by enabling parallel machining operations. The upper turret includes a Y-axis (±50 mm to 100 mm travel depending on configuration), allowing milling, drilling, and off-center machining.

The machine is equipped with integrated motor spindles, with the main spindle reaching speeds of around 5,500 rpm and the counter spindle up to 6,000 rpm. Live tooling speeds can reach up to 12,000 rpm, enabling high-speed milling operations within the turning center.

Built with a rigid structure and direct measuring systems, the CTX 350 4A ensures high positioning accuracy (around 6 microns) and excellent thermal stability. It is available with Siemens or MAPPS Fanuc controls, along with DMG MORI’s CELOS interface, simplifying programming and shopfloor integration.

Designed for maximum cutting time utilization, the machine integrates well with automation systems such as bar feeders and robotic loading. Overall, the CTX 350 4A delivers a powerful combination of speed, flexibility, and precision, making it ideal for high-efficiency production environments.

WHY BUY USED DMG MORI CTX 350 4A

Buying a used DMG MORI CTX 350 4A is a strong strategic move for manufacturers seeking high-productivity turning with multi-tasking capability at a reduced investment. Machines with dual turrets and dual spindles represent a significant capital cost when new, but in the used market, they offer exceptional value relative to their productivity.

One of the main advantages is cost efficiency. A new CTX 350 4A with full options—dual turrets, Y-axis, live tooling, and automation—can be a major investment. Purchasing used allows businesses to access these advanced capabilities at a significantly lower price, making it easier to scale production capacity.

Cutting time (spindle hours) is the most important factor when evaluating a used CTX 350 4A. Because this machine is designed for simultaneous machining, it often accumulates higher utilization than standard lathes. Machines with lower cutting hours will typically have better spindle condition, turret alignment, and guideway accuracy. For example, a machine from the early 2010s with moderate usage may provide better long-term reliability than a newer machine used in 24/7 production.

Another advantage is productivity. The dual-turret configuration allows overlapping operations, meaning even a used machine can significantly reduce cycle times compared to single-turret machines. This is especially valuable in high-volume production where efficiency directly impacts profitability.

Additionally, DMG MORI’s strong global service network and parts availability reduce the risks associated with purchasing used equipment. Maintenance support, spare parts, and technical expertise remain accessible even for older machines.

From a financial standpoint, buying used enables faster return on investment. With lower upfront costs and the ability to maintain high cutting time utilization, a used CTX 350 4A can quickly contribute to increased throughput and profitability.

HOW MUCH DOES A USED DMG MORI CTX 350 4A COST?

The cost of a used DMG MORI CTX 350 4A depends on manufacturing year, machine configuration, condition, and most importantly, cutting time (spindle hours). Because of its dual-turret, dual-spindle architecture, it typically commands higher prices than standard CTX or CLX models.

Machines built before 2000 (or earlier-generation twin-turret turning centers with similar capability) generally range from $20,000 to $60,000. These machines are the most affordable but may include outdated controls and higher wear levels. Cutting time is especially critical—machines with high spindle hours may require turret rebuilds or spindle servicing.

Models produced between 2000 and 2010 typically range from $60,000 to $130,000. This segment often provides the best balance between price and performance, offering improved CNC controls, better spindle technology, and enhanced reliability. Units with low to moderate cutting time are particularly desirable, as they can deliver strong performance with manageable maintenance costs.

Machines from 2010 to 2025 generally range from $130,000 to $280,000 or more, depending on configuration, automation integration, and overall condition. Machines equipped with full Y-axis capability, high-speed live tooling, and robotic automation command premium prices due to their high productivity.

Cutting time remains the most critical pricing factor. A newer machine with excessive spindle hours—especially one used for simultaneous machining—may be less valuable than an older unit with lower usage. Buyers should carefully evaluate spindle condition, turret synchronization accuracy, maintenance records, and control system performance to determine true value and ensure long-term operational reliability.
