Overview

The DMG Mori CTX 350 is a compact universal turning center that bridges the gap between the entry-level CLX series and the heavy-duty CTX beta/gamma machines. Built around a rigid 30-degree slant bed with box guideways, the CTX 350 delivers the kind of thermal stability and surface finish quality that shops expect from DMG Mori, but in a footprint that works for smaller facilities. It is the machine you reach for when the CLX 350 does not have enough milling capability and the CTX beta is more machine than you need.

The main spindle delivers 22 kW (29.5 hp) at 5,000 RPM with 350 Nm (258 ft-lb) of torque. That is a meaningful step up from the CLX 350 at 16.5 kW and provides real authority for interrupted cuts in steel and stainless. Bar capacity is 65 mm (2.56 in) through an A2-6 spindle nose, with standard 8-inch or optional 10-inch chucks. Maximum turning diameter reaches 320 mm (12.6 in) with up to 535 mm (21.1 in) of turning length.

What separates the CTX from the CLX is the milling side. The CTX 350 comes standard with a VDI 30 turret but can be configured with DMG Mori’s BMT 45 turret, which puts driven tool motors inside the turret body rather than bolting them externally. This delivers up to 6,000 RPM at the driven tool with 16 Nm of continuous torque, more than enough for cross-drilling, hexes, flats, and keyways. The optional Y-axis adds plus/minus 40 mm of travel for off-center features.

Thermal management on the CTX 350 includes cooled ball screws and a temperature-controlled spindle housing. These features keep dimensional stability across production runs that would cause drift on uncompensated machines. The C-axis provides 0.001-degree indexing for precise angular positioning during milling operations.

The CTX 350 runs CELOS with FANUC or Siemens underneath. Pricing starts around ,000 and can reach 85,000 with Y-axis, sub-spindle, BMT turret, and automation preparation. Used units from 2017-2022 trade between ,000 and ,000. Direct competitors include the Mazak QT-200MSY, Okuma LB2000 EX III MY, and Doosan Puma 2100SY.

Strengths & Limitations

Strengths

22 kW spindle with 350 Nm torque provides meaningful cutting authority for steel and stainless, a 33% power increase over the CLX 350 in the same frame size
BMT 45 turret option places driven tool motors inside the turret body for better rigidity and vibration damping than bolt-on VDI live tooling designs
65 mm bar capacity handles common bar stock sizes for production turning, matching the CLX 450 despite the smaller overall machine envelope
Cooled ball screws and temperature-controlled spindle housing maintain dimensional stability across long production runs without climate-controlled environments
Compact footprint suitable for shops with floor space constraints that still need real milling capability beyond what the CLX series offers
C-axis with 0.001-degree indexing and optional Y-axis enable precise angular positioning for complex milled features on turned parts

Limitations

Starting at K, it costs 40-50% more than a Haas ST-15Y or Doosan Lynx 2600SY that cover similar turning envelopes
320 mm max turning diameter and 535 mm turning length limit workpiece size, and shops regularly exceeding these dimensions should look at the CTX 450 or CTX 550
6,000 RPM driven tool speed on the BMT 45 is lower than the 10,000-12,000 RPM available on larger CTX and NLX machines with BMT 60 turrets
DMG Mori parts and service pricing remains among the highest in the industry, and regional service quality varies based on dealer network coverage

Best For

Job shops producing small-to-mid-size turned parts with milled features that need done-in-one capability to eliminate secondary operations Medical and dental component manufacturers turning and milling precision parts from stainless steel, titanium, and CoCr alloys Automotive suppliers producing bar-fed components up to 65 mm diameter with cross-drilled holes, flats, or hexes Shops upgrading from basic 2-axis lathes to a mill-turn platform without the complexity and cost of a full multitasking machine Production environments planning to scale into Robo2Go automation for unattended turning and milling cycles

Frequently Asked Questions

01 What does a DMG Mori CTX 350 cost?

A new CTX 350 in base configuration starts around ,000. Adding BMT 45 turret, Y-axis, sub-spindle, and automation prep pushes the price to 8,000-85,000. Used CTX 350 machines from 2017-2022 trade between ,000 and ,000 depending on options and condition.

02 What is the difference between the CTX 350 and CLX 350?

The CTX 350 has a more powerful spindle (22 kW / 350 Nm vs 16.5 kW / 232 Nm), larger bar capacity (65 mm vs 51 mm), and the BMT 45 turret option for superior milling. The CLX 350 is a simpler, lower-cost turning center with optional driven tools. Choose the CTX if milling capability is important; the CLX if you primarily do straight turning.

03 What is the BMT 45 turret?

BMT (Built-in Motor Turret) places the driven tool motor inside the turret body rather than externally. The 45 designates the tool interface size. On the CTX 350, BMT 45 provides up to 6,000 RPM and 16 Nm continuous torque at the driven tool. This design delivers better rigidity and less vibration than conventional VDI live tooling setups.

04 How does the CTX 350 compare to the Mazak QT-200MSY?

Both are compact mill-turn centers for similar work envelopes. The DMG Mori has the BMT turret advantage for milling rigidity and the CELOS interface. The Mazak offers MAZATROL conversational programming, which is faster for job shop short-run work. Mazak service is generally rated higher in North America. Pricing is competitive, with the DMG Mori typically -15K higher.

05 Can I add a sub-spindle to the CTX 350?

Yes. The CTX 350 is available with an optional counter-spindle for backworking, enabling complete part machining in a single setup. The sub-spindle adds part pickup, backside turning, and the ability to produce finished parts without manual intervention. This option adds approximately ,000-,000 to the base price.
