Universal turning center for complete 6-sided machining

DMG MORI has introduced the CTX 450 4A, a new universal turning center designed for flexible, high-precision complete machining with up to four axes, dual spindles, and multiple turret configurations for demanding production environments.

Machine concept and positioning
The CTX 450 4A extends DMG MORI’s latest generation of universal turning centers, combining a compact footprint of 10.8 m² with a configuration aimed at six-sided complete machining. The machine supports workpieces up to Ø 430 × 700 mm and is designed to serve applications where flexibility, accuracy, and automation are required, including subcontract manufacturing and component production for demanding industries.

Up to 36 tool positions are available across two tool carriers. These can operate independently or simultaneously on the main and counter spindle, enabling parallel machining strategies that reduce cycle times and improve throughput.

Accuracy and mechanical design
The machine’s rigid structure is complemented by an integrated cooling concept and Magnescale position measuring systems on both X-axes, the Y-axis, and optionally the Z-axis. This configuration supports a positioning accuracy of 6 µm (12 arcseconds), providing the precision required for tight-tolerance turning and milling operations.

The Y-axis offers a travel range of ±65 mm, extending the scope of off-center milling and drilling operations within the same setup.

Spindle and turret configurations
In its standard configuration, the CTX 450 4A is equipped with two motor spindles. The left spindle (ISM 80) delivers up to 4,500 rpm and 280 Nm, while the right spindle (ISM 65) provides up to 5,500 rpm and 171 Nm. Optional spindle variants extend the machine’s capability for heavy-duty machining, including an ISM 102 spindle with 3,500 rpm and 620 Nm.

The bar capacity of up to Ø 102 mm positions the CTX 450 4A at the upper end of its class for bar-fed turning applications.

Turret options further enhance flexibility. The upper turret supports 12 or 16 VDI 40 tool stations, while the lower turret accommodates 12 stations. Both turrets enable milling and drilling at up to 12,000 rpm with 38 Nm. Optional VDI 30 turrets increase tool capacity to up to 20 stations on the upper turret and 16 on the lower, supporting high tool density for complex parts.




Automation and digital integration
To increase machine utilization, DMG MORI offers integrated automation options. An unloading device is available ex works for handling parts up to Ø 100 × 350 mm and 4 kg. Additional automation can be implemented using Robo2Go Turning, extending the system toward unattended or lights-out production.

Digital connectivity is supported via the CELOS X platform, available with Siemens SINUMERIK ONE or MAPPS control environments. App-based workflows enable monitoring, setup assistance, and integration into broader digital manufacturing systems. Technology cycles such as the tool balancing assistant and Multi-Threading Pro are intended to reduce programming effort and stabilize machining processes.

Resource efficiency and sustainability
The CTX 450 4A incorporates DMG MORI’s GREENMODE measures, which focus on reducing energy and resource consumption without compromising productivity. Depending on the application, energy consumption can be reduced by more than 30% through measures such as low-friction linear guides, high-efficiency cooling units, demand-based coolant supply using Adaptive Coolant Flow, and automatic air leakage monitoring.

These features address both operational cost reduction and sustainability requirements, which are increasingly relevant in machine tool investment decisions.

Application perspective
By combining compact design, high tool capacity, dual spindles, and integrated automation, the CTX 450 4A targets manufacturers seeking to consolidate processes into a single machine. The platform is positioned to support flexible batch sizes, complex geometries, and increasing demands for automation and digital integration in modern turning operations.
