CNC Lathes
CNC lathes are the most-traded segment in MBR's portfolio — from simple basic lathes to fully equipped turn-mill centers with sub-spindle and Y-axis. What separates a good used machine from an expensive mis-investment?
Categories and configurations
Basic CNC lathes (X/Z, no driven tools)
Simplest configuration: main spindle, turret without driven tools, two linear axes. For standard turn parts without milling or drilling, economical and low-maintenance. Typical examples: Mazak Quick Turn 200, DMG Mori CTX 310 eco, Gildemeister CTX 400 E.
2026 market position: Mazak QT 200 (built 2010–2015) and DMG Mori CTX 310 eco (built 2012–2016, Fanuc 0i) sit in the entry segment.
Turn-mill centers (driven tools, ±Y-axis)
Driven tools in the turret allow milling, drilling and tapping off the lathe axis. With Y-axis, eccentric operations can be performed at full precision — decisive for complex turn parts with cross-holes, slots and milled surfaces.
Relevant models: DMG Mori NLX 2500SY, Mazak Quick Turn 350 My II, INDEX C200 / C400, Doosan Puma 2600SY.
2026 market position: DMG Mori NLX 2500SY/700 (built 2016–2019) sits in the upper segment, Mazak QT 350 My II (built 2015–2018) in mid-to-upper segment.
Turn-mill centers with sub-spindle
The sub-spindle takes over the workpiece after front-side machining for back-side machining — without re-fixturing. That enables complete-part machining in one setup and is the decisive productivity advantage in series production.
On the used market the sub-spindle commands a measurable premium and lifts the machine into a higher market segment versus comparable machines without one. Important: check sub-spindle condition separately — in operation it's often less intensively maintained than the main spindle.
Large lathes (Ø >500 mm, length >2 m)
For shafts, rings and large parts in energy, shipbuilding and heavy machine-building. Typical examples: DMG Mori NLX 4000 / 6000, Mazak Quick Turn Nexus 450 / 550, Weiler Praktikant / Centor. Used market is tighter — fewer offers, more complex logistics, smaller buyer base. Prices are negotiation-dependent.
Manufacturer comparison
DMG Mori (NLX series)
Most-traded turn-mill centers in MBR's portfolio. Fanuc 31i/32i controller, broad buyer base, good export-market suitability. SY variants (sub-spindle + Y-axis) are the most liquid models overall. Strengths: service network, controller robustness, spare-parts supply.
Mazak (Quick Turn)
Mazatrol controller with conversational programming interface — intuitive for experienced Mazak operators. Smooth controller generation (from 2014) clearly preferred. My II variant with Y-axis is the preferred export model. Strengths: Mazak service quality, programming ergonomics, wide distribution in contract manufacturing.
INDEX (C series)
High-end German turn-mill centers for demanding series production. INDEX C200, C400, G200 with Siemens 840D controller. Less liquid on the used market than DMG Mori or Mazak, but technically excellent and sought in precision shops. Strengths: rigidity, precision, multi-spindle concepts.
Gildemeister / Mori Seiki (legacy models)
Before the DMG-Mori merger (2013), Gildemeister produced robust CTX lathes (Siemens 840D) and Mori Seiki the high-end SL series (Fanuc/MSX controller). High quality, but spare parts for older MSX controllers can become scarce. Clarify before purchase.
Inspection points on CNC lathes
- Main-spindle hours: Guideline for A-grade machines: under 8,000 h. Above 15,000 h acceptable with documented maintenance. Test spindle at various RPM (500 / 2,000 / max) — running quality, noise, temperature.
- Sub-spindle hours (separately): Often 30–50% less used than the main spindle. Still check condition — sub-spindle repair is expensive (€3,000–10,000+).
- Turret accuracy: Run all positions, measure positioning accuracy, check for backlash and latching errors. Turret wear is a frequent and underestimated cost factor.
- Alarm history: Controller: read out all stored alarms for the last 12–24 months. Recurring servo, temperature or NC alarms are warning signs.
- Coolant system: Pressure, flow, pump condition. Check coolant condition (concentration, contamination).
- Bar-feeder interface: If bar-feeder exists or is planned — interface condition, available conversion parts, compatibility with planned bar-feeder.
What MBR offers on CNC lathes
- Acquisition: MBR buys turn-mill centers directly — with clear valuation in 24–48 h. Focus: machines with sub-spindle and Y-axis from DMG Mori, Mazak and INDEX.
- Sourcing: Looking for a specific model? MBR searches the European dealer and industry network — not just public exchanges.
- Inspection: Spindle tests (main + sub), turret check, alarm history, complete written report.
- Export: Turn-mill centers are the most-exported segment from MBR's portfolio — particularly to Turkey and MENA. Full export documentation included.
Frequently asked
What does a used CNC lathe cost? +
Basic CNC lathes from €15,000. Turn-mill centers with Y-axis and sub-spindle (Mazak QT My II, NLX SY): €55,000–115,000. Key price factors: sub-spindle (+€15,000–30,000), Y-axis (+€10,000–20,000), Smooth/Fanuc controller vs. older platform.
Is the sub-spindle premium worth it? +
Yes — if your parts need back-side machining. The sub-spindle eliminates re-fixturing, reduces setup times and enables complete-cycle parts. On runs over 100 units the premium pays back fast. On front-side-only parts it brings no advantage.
What to watch for on used turn-mill centers? +
Check spindle hours on both spindles separately, measure turret accuracy, read alarm history for the last 12 months. Most common expensive surprises: worn turret (€1,500–4,000) and neglected sub-spindle (€3,000–10,000).
