Overview

The DMG Mori CTX beta 1250 TC is a highly capable mill-turn center designed to complete complex turned and milled components in a single setup. The machine combines a powerful turning spindle with a fully interpolating B-axis milling head, enabling 5-axis simultaneous machining of complex geometries that would otherwise require multiple machines and setups.

The CTX beta 1250 TC features a main spindle rated at 5,000 rpm and a counter spindle that mirrors the main spindle's capabilities, allowing full front and back machining of bar-fed parts without operator intervention. The integrated Y-axis and B-axis milling head positions tooling at any angle from 0° to 180°, enabling undercuts, angled bores, and complex contours to be machined with a single tool path.

Driven by a Siemens SINUMERIK ONE or DMG Mori's own CELOS control platform, the CTX beta 1250 TC leverages digital twin technology to simulate machining operations offline before cutting the first chip. This capability reduces programming errors and shortens setup times significantly, which is critical when machining expensive workpiece materials or tight-tolerance aerospace components.

With a maximum turning diameter of 500 mm and a turning length of 1,250 mm, the CTX beta 1250 TC addresses a broad range of complex prismatic and rotational components. It is a leading choice for aerospace, medical device, and high-precision automotive suppliers seeking to reduce work in process and eliminate re-fixturing error.

Strengths & Limitations

Strengths

Full 5-axis simultaneous machining via B-axis and Y-axis eliminates multiple setups for complex parts
Counter spindle enables complete front-and-back part machining in one continuous cycle
SINUMERIK ONE digital twin dramatically reduces programming time and costly machining errors
High-torque main spindle handles heavy roughing in titanium, Inconel, and hardened steel
CELOS app-based control interface simplifies setup documentation and process repeatability

Limitations

Premium price point places it out of reach for smaller job shops without steady complex part volumes
Programming complexity of 5-axis mill-turn requires skilled CAM programmers and experienced operators
Large machine footprint and significant installation requirements (foundation, coolant, utilities)

Best For

Aerospace manufacturers producing complex structural parts, shafts, and housings in one setup Medical device manufacturers machining implants and surgical instruments from titanium and cobalt-chrome High-precision automotive suppliers eliminating re-fixturing error on critical rotating parts Defense contractors requiring complete complex parts from expensive billet material with minimal scrap

Frequently Asked Questions

01 What is the B-axis swivel range on the CTX beta 1250 TC?

The B-axis milling head swivels from −30° to +210°, providing full angular access for undercuts, angled bores, and complex contour milling without repositioning the workpiece.

02 Can the CTX beta 1250 TC machine parts completely from bar stock?

Yes. With a bar loader attached to the main spindle and the counter spindle handling backworking operations, the CTX beta 1250 TC can fully machine front and back features of bar-fed parts in a single automated cycle.

03 What does the CELOS control add over a standard Siemens control?

CELOS is DMG Mori's app-based control layer that runs on top of SINUMERIK ONE. It provides digital job management, maintenance apps, tool management, and connectivity to DMG Mori's cloud services, making it easier to document setups, track performance, and integrate into Industry 4.0 environments.

04 How does the CTX beta 1250 TC compare to dedicated turning centers for pure turning work?

For high-volume pure turning, a dedicated turning center will typically be more cost-effective. The CTX beta 1250 TC's value is maximized on complex parts that combine significant turning and milling requirements, where eliminating secondary setups reduces cost per part and re-fixturing errors.

05 What materials is the CTX beta 1250 TC best suited for?

The machine handles steel, stainless steel, aluminum, titanium, Inconel, and cobalt-chrome alloys. Its high-torque spindle and rigid construction make it particularly effective for difficult-to-machine aerospace and medical materials.
