Overview

The DMG Mori CTX beta 450 TC is the entry point to the CTX turn-mill lineup, positioned above the CLX TC series and below the CTX beta 1250 TC. Where the CLX TC machines dip their toes into multitasking, the CTX beta 450 TC delivers the full turn-mill experience with a more powerful compactMASTER B-axis spindle, wider angular range, and optional sub-spindle for true 6-sided complete machining.

The main spindle is an ISM 76 integrated motor spindle producing 29 kW (39 hp) at 5,000 RPM with 350 Nm of torque through a 10-inch chuck. Bar capacity is 65 mm (2.6 in). The optional sub-spindle matches the main at 29 kW and 5,000 RPM, enabling done-in-one processing for parts needing backside work.

The compactMASTER turn-mill spindle runs at 12,000 RPM with 18.5 kW (25 hp) and 79 Nm of torque through an HSK-A63 interface. The B-axis swivels through a full 240-degree range (plus/minus 120 degrees) via Direct Drive Motor, giving you simultaneous 5-axis capability that the CLX TC machines simply cannot match.

Axis travels are 260 mm (10.2 in) in X, 200 mm (7.9 in) in Y (plus/minus 100 mm), and 505 mm (19.9 in) in Z. Maximum turning diameter is 400 mm (15.7 in) with a turning length of 450 mm (17.7 in). Rapid traverse hits 36 m/min on X and Y, 40 m/min on Z. The standard disc magazine holds 24 tools, expandable to 48. An optional 12-position lower turret with VDI 40 tooling adds parallel processing. The machine weighs approximately 10,500 kg (23,148 lb) and occupies 3,400 x 2,450 mm. Pricing starts around $350,000, with production configs running $420,000-$500,000.

Strengths & Limitations

Strengths

Full 240-degree B-axis range with Direct Drive Motor matches the CTX beta 1250 TC and NTX series, giving true simultaneous 5-axis capability in a smaller package
18.5 kW compactMASTER milling spindle at 12,000 RPM with HSK-A63 delivers genuine machining center-class milling performance
Optional sub-spindle enables true 6-sided done-in-one processing, eliminating part handling that CLX TC machines require
Optional 12-position lower turret with VDI 40 tooling allows parallel processing to cut cycle times on production runs
200 mm Y-axis travel (plus/minus 100 mm) is double the CLX TC machines, critical for off-center milling and complex contour work
24-to-48 tool magazine handles complex parts with deep tool libraries without manual intervention
CELOS with Siemens 840D sl provides the same programming environment as the larger CTX and NTX machines

Limitations

Starting at $350K, it costs $100K more than the CLX 450 TC for the same basic work envelope (400 x 450 mm)
65 mm bar capacity matches the CLX 450 TC; shops needing larger bar stock should look at the CLX 550 TC or CTX beta 1250 TC
At 10,500 kg, significantly heavier than the CLX 450 TC, requiring more substantial foundations
Programming complexity jumps with the sub-spindle and lower turret options; expect 3-6 months to get operators fully productive
DMG Mori service costs and parts pricing tend to run higher than Japanese competitors for this size class

Best For

Aerospace tier-2 suppliers machining complex turned-and-milled components needing full 5-axis B-axis access in a compact machine Medical device manufacturers producing implants and instruments requiring done-in-one processing with sub-spindle backworking Job shops running high-mix, high-complexity chuck-work parts where the CLX TC limited B-axis range is a bottleneck Precision shops stepping up from live tooling lathes to true turn-mill capability with genuine milling spindle power Production environments needing parallel processing via the lower turret to reduce cycle times

Frequently Asked Questions

01 What does a DMG Mori CTX beta 450 TC cost?

DMG Mori quotes the CTX beta 450 TC per configuration and the spread is wide because most of the capability is optional. The sub-spindle, the 12-position VDI 40 lower turret, the 48-tool magazine over the standard 24, high-pressure through-spindle coolant, bar feed and parts handling, and automation are all separate line items on the quote. HSK-A63 tooling for the compactMASTER milling spindle and VDI 40 holders for the lower turret are a further cost, and installation for a 10,500 kg machine in a 3.4 x 2.45 m footprint is separate again.

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

The CTX beta 450 TC has a more powerful 18.5 kW milling spindle (vs 12 kW), an HSK-A63 interface (vs Capto C4), 240 degrees of B-axis range (vs 110), an optional sub-spindle, an optional lower turret, and 200 mm of Y-axis travel (vs 100 mm). The CLX 450 TC is the value-line machine and is priced a clear step below. If you only need light milling on turned parts the CLX covers it; if you need real B-axis milling or done-in-one, the CTX is the machine.

03 Should I get the CTX beta 450 TC or the CTX beta 1250 TC?

The 1250 TC has a much larger work envelope (600 mm diameter x 1,200 mm length vs 400 x 450 mm), bigger spindles (33 kW vs 29 kW), and 102 mm bar capacity (vs 65 mm). If your parts fit inside the 450 TC envelope there is real money and floor space saved by staying with the smaller machine — and a shorter Z axis is generally the more rigid one.

04 What CAM software supports the CTX beta 450 TC?

Esprit, hyperMILL, and Mastercam with the mill-turn module all support CTX TC programming. Plan on a turn-mill CAM licence plus a machine-specific post and a verified simulation model — with a B-axis milling spindle, an optional sub-spindle and a lower turret sharing the envelope, collision checking is not optional. CAM vendors price per seat and per module, so get that quoted alongside the machine.

05 Can the CTX beta 450 TC cut gears?

Yes. DMG Mori gearSKIVING and gearMILL technology cycles work through the B-axis compactMASTER spindle for spur, helical, and bevel gears.
