Overview

The DMG Mori CTX 450 is the mid-range workhorse in DMG Mori’s universal turning lineup, offering a bigger work envelope and more spindle authority than the CTX 350 while staying below the heavy-duty CTX 550 and CTX beta machines. It is the machine most shops land on when they need legitimate milling capability on a turning platform without jumping to a full multitasking center. The combination of 400 mm (15.7 in) turning diameter, 1,100 mm (43.3 in) turning length, and BMT turret technology makes it a genuine mill-turn workhorse.

The main spindle pushes 25.5 kW (34.2 hp) at 4,000 RPM with 450 Nm (332 ft-lb) of torque through an A2-8 spindle nose. That is serious authority for interrupted cuts in stainless, Inconel, and other tough materials. Bar capacity is 65 mm (2.56 in) with a standard 10-inch chuck. The optional sub-spindle enables backworking for complete part processing from bar stock without manual intervention.

The milling side is where the CTX 450 earns its keep. The BMT 55 turret option spins driven tools at up to 10,000 RPM with 30 Nm of continuous torque, enough for cross-drilling, pocketing, hex machining, and keyways in steel. The Y-axis provides plus/minus 52.5 mm of travel for off-center features. Combined with the C-axis at 0.001-degree indexing, the CTX 450 handles most mill-turn work that would otherwise require a second operation on a machining center.

Thermal compensation includes cooled ball screws, spindle temperature management, and DMG Mori’s bed temperature control system. Box guideways on the Z-axis and roller guideways on the X-axis provide a balance of damping and speed. The 12-station turret keeps tool changes fast, and the CELOS interface with FANUC or Siemens underneath provides the same workflow management found across the lineup.

Pricing starts around 60,000 and can reach 30,000 with Y-axis, sub-spindle, BMT turret, and automation preparation. Used CTX 450 machines from 2016-2022 trade between 5,000 and 40,000. Direct competitors include the Mazak QT-250MSY, Okuma LB3000 EX II MY, and Doosan Puma 2600SY.

Strengths & Limitations

Strengths

25.5 kW spindle with 450 Nm torque provides serious cutting authority for interrupted cuts and heavy roughing in stainless, Inconel, and hardened steels
BMT 55 turret spins driven tools at up to 10,000 RPM, delivering real milling capability that eliminates second operations for cross-holes, flats, and pockets
400 mm turning diameter and 1,100 mm turning length cover a wide range of shaft and chuck work without stepping up to larger, more expensive machines
Thermal compensation system with cooled ball screws and spindle temperature management holds tolerances across production shifts in non-climate-controlled shops
Y-axis with plus/minus 52.5 mm travel enables off-center milling and drilling that would otherwise require transferring parts to a machining center
CELOS interface provides unified workflow across DMG Mori’s entire lineup, reducing training time for operators moving between machines

Limitations

65 mm bar capacity is adequate but falls short of the NLX 2500’s 105 mm, limiting bar-fed work to smaller stock diameters
4,000 RPM max spindle speed is slower than the CTX 350’s 5,000 RPM, which can limit surface footage on smaller-diameter aluminum parts
Starting at 60K, it costs 30-40% more than a Mazak QT-250M or Doosan Puma 2600 for similar turning capacity
12-station turret limits tool positions for complex multi-operation parts compared to competitors offering 16 or 24 stations
DMG Mori service and parts costs remain among the highest in the industry, impacting total cost of ownership

Best For

Job shops handling a mix of shaft and chuck work that regularly needs milled features done in one setup Automotive and hydraulic component suppliers producing parts from bar stock up to 65 mm diameter Aerospace subcontractors machining Inconel, titanium, and stainless components that demand torque and thermal stability Production environments planning to add Robo2Go or gantry loader automation for unattended mill-turn cycles Shops standardized on DMG Mori CELOS wanting a mid-size turning platform that matches their existing workflow

Frequently Asked Questions

01 What does a DMG Mori CTX 450 cost?

A new CTX 450 starts around 60,000. Adding BMT 55 turret, Y-axis, sub-spindle, and Robo2Go prep pushes the price to 10,000-30,000. Used machines from 2016-2022 sell between 5,000 and 40,000.

02 What is the difference between the CTX 450 and CLX 450?

The CTX 450 is designed as a mill-turn platform with the BMT 55 turret option (10,000 RPM driven tools), larger Y-axis stroke, and higher spindle torque (450 Nm vs 426 Nm). The CLX 450 is a turning-first machine with optional driven tools via VDI 40 turret.

03 How does the CTX 450 compare to the Mazak QT-250MSY?

Both are mid-size mill-turn centers. The DMG Mori has the BMT turret advantage (10,000 RPM driven tools vs typical 6,000 RPM), better thermal compensation, and larger Y-axis stroke. The Mazak offers MAZATROL conversational programming and generally better North American service.

04 What is the BMT 55 turret?

BMT integrates the driven tool motor inside the turret body. The 55 designates the turret size. On the CTX 450, BMT 55 delivers up to 10,000 RPM and 30 Nm continuous torque, providing superior rigidity during milling.

05 Can I automate the CTX 450?

Yes. The CTX 450 supports Robo2Go collaborative robot loading, integrated bar feeders, and gantry loaders. CELOS includes automation management apps for robot routines.
