Overview
The DMG Mori CTX 450 is a universal CNC turning center engineered for high precision and flexibility in the machining of small to medium-sized rotational components. Built on a slant-bed design with a thermally symmetric cast-iron base, the CTX 450 maintains dimensional accuracy over extended production runs by minimizing thermal drift — a critical requirement for aerospace and medical part tolerances.
With a maximum swing of 450 mm and between-centers distance options up to 1,000 mm, the CTX 450 accommodates a broad range of shaft and chucked parts. The main spindle offers up to 4,500 rpm with 17 kW of power and 300 Nm of torque, handling both aluminum and steel workpieces efficiently. An optional counter spindle and Y-axis capability transform the CTX 450 into a turn-mill center capable of completing complex parts in a single clamping.
The BMT (Built-in Motor Turret) or VDI tool turret options provide driven tool capability for milling, drilling, and threading operations off the main centerline, supporting complete machining without secondary setups. The machine's chip management system and coolant circuits are engineered for production environments requiring continuous operation.
Controlled via CELOS with a Siemens 840D sl or Fanuc 31i control, the CTX 450 offers intuitive programming and process monitoring. Its compact footprint and broad capability range make it a versatile addition to any precision machining facility producing components for aerospace, automotive, hydraulics, or general engineering.

Strengths & Limitations
Strengths
- Thermally symmetric slant-bed structure minimizes thermal drift for consistent dimensional accuracy
- Optional counter spindle and Y-axis enable complete part machining in a single clamping
- BMT driven turret supports milling and drilling without leaving the turning center
- Compact footprint relative to capability; suitable for smaller precision shops
Limitations
- 65 mm bar capacity is moderate — larger bar work requires a higher-capacity turning center
- Y-axis and counter spindle are options that add significantly to the base machine price
- 4,500 rpm main spindle speed is conservative for high-speed aluminum turning applications

Frequently Asked Questions
01
The CTX 450 has a 65 mm spindle bore, accommodating bar stock up to 65 mm in diameter. For larger bar work requiring through-spindle feeding, a higher-capacity turning center such as the CTX 650 or CTX 800 would be more appropriate.
02
Yes. With the optional BMT or VDI driven tool turret, the CTX 450 can perform milling, drilling, tapping, and off-center operations using live tools at up to 6,000 rpm. Adding the optional Y-axis further extends this capability to full off-centerline milling for complex prismatic features.
03
The CTX 450 is available with either a Siemens 840D sl or Fanuc 31i control, both integrated with the CELOS operator interface for app-based process management, tool management, and machine condition monitoring.
