Overview
The DMG Mori CLX 750 is the flagship of the CLX compact CNC turning center family, designed to handle large shaft components up to 1,290 mm (50.8 in) turning length within the smallest machine footprint available at this capacity class. The CLX series philosophy — delivering production turning capability in a compact, affordable, and highly accessible package — reaches its fullest expression in the CLX 750, which extends the CLX family's turning length far beyond the CLX 550 and CLX 450 to address shaft and bar work that smaller CLX models cannot touch.
With a maximum turning diameter of 400 mm (15.7 in) and turning length of 1,290 mm (50.8 in), the CLX 750 handles camshafts, crankshafts, long spindles, pump shafts, and hydraulic cylinder rods that are standard output for automotive tier suppliers, hydraulics manufacturers, and general industrial shops. The 18.5 kW (24.8 hp) spindle at 3,500 RPM provides the balanced combination of speed and torque appropriate for the diameter range. The A2-6 spindle nose takes a standard 10-inch (254 mm) chuck.
The CLX series uses slant-bed construction with linear guideways for fast rapid traverse. The Z-axis rapid traverse reaches 40 m/min (1,575 ipm), enabling fast tool positioning across the full 1,290 mm travel length. The 12-position turret is available in VDI 40 configuration with optional driven tools up to 5,000 RPM and 20 Nm, enabling basic milling, drilling, and threading operations on turned parts without a secondary machine setup.
Control runs CELOS with Siemens 840D solutionline or Fanuc 31i-B as standard options. The CELOS interface provides DMG Mori's production monitoring, tool management, and connectivity tools that match the CLX 750 to Industry 4.0 connected shop environments. Bar capacity of 65 mm (2.6 in) accommodates standard bar stock sizes common in automotive and general industrial production.
For shops that consistently machine shaft components in the 600-1,290 mm length range and need a production turning center that fits into a standard shop floor without special foundation work, the CLX 750 delivers capable, reliable performance at a price point well below the NLX or CTX gamma series. It competes with the Mazak Quick Turn 350MY, Okuma LB3000EX II, and Doosan Puma 2600M. Specs sourced from DMG Mori published data.

Strengths & Limitations
Strengths
- 1,290 mm turning length addresses long shaft work — camshafts, pump shafts, and cylinder rods — that smaller CLX models cannot accommodate
- Compact footprint for a 1,290 mm turning length machine enables installation on standard shop floors without overhead crane requirements
- CLX series value pricing at $120K-$200K delivers DMG Mori quality and CELOS controls at a price accessible to smaller shops
- Linear guideways and 40 m/min Z-rapid provide fast cycle times on long-shaft production runs
- CELOS with Siemens 840D solutionline provides full connectivity and tool management on a mid-range production machine
- Optional driven tooling enables basic milling, drilling, and threading on turned parts without secondary machine transfer
- 5,200 kg machine weight is manageable with standard rigging, no special foundation typically required
Limitations
- 400 mm maximum turning diameter limits the CLX 750 to medium-diameter shaft work — large flanged components and big chucking work need the NLX 4000 or larger
- 18.5 kW spindle power is modest compared to NLX or CTX series — aggressive material removal in tough alloys requires conservative parameters
- 5,000 RPM driven tools at 20 Nm are adequate for basic live tooling but limited for productive milling operations on complex parts
- No Y-axis option means complex off-center features require secondary machining center operations
- Linear guideways, while fast, provide less rigidity than box guideways on NLX machines during heavy interrupted cuts
- 65 mm bar capacity is the maximum for this class, limiting bar-fed applications to standard bar sizes below 65 mm

Frequently Asked Questions
01
A new CLX 750 starts around $120,000 in base configuration with Fanuc control. Adding Siemens 840D solutionline, driven tooling, and additional options pushes pricing to $160,000-$200,000. Used CLX 750 machines from 2016-2022 typically sell for $55,000-$110,000 depending on condition and options.
02
The CLX 750 extends turning length from 850 mm (CLX 550) to 1,290 mm, enabling longer shaft work. Maximum turning diameter increases from 380 mm to 400 mm. The CLX 750 also adds a larger 10-inch chuck (versus 8-inch on the CLX 550) and higher Z-rapid traverse. Choose the CLX 750 when you routinely machine parts longer than 850 mm.
03
The CLX 750 does not offer a Y-axis. For off-center milling capability with turning length in this range, consider the NLX 4000 Y which provides Y-axis travel with significantly more spindle power. The CLX 750 is a straight turning center (with optional live tooling) focused on efficient shaft production.
04
Yes. The 65 mm bar capacity is suitable for standard bar stock in common sizes. A bar feeder can be fitted for automated bar-fed production. For bar work exceeding 65 mm diameter, consider the NLX 4000 with 102 mm bar capacity.
05
The CLX 750 is available with either Siemens 840D solutionline with CELOS or Fanuc 31i-B with CELOS. Siemens is recommended for shops already using Siemens controls or those wanting full CELOS X app capability. Fanuc is preferred in shops with Fanuc programming expertise or those prioritizing lowest total cost of ownership.
