Used 5-Axis CNC Machining Center — Buying Criteria

A used 5-axis machining center is one of the most rewarding investments in metal cutting — provided you know what to look for. A new Hermle C 42 U or DMG Mori DMU 80 eVo runs 350 000-700 000 EUR. On the German second-hand market, the same models from 2016-2020 appear at 120 000-280 000 EUR. The savings are substantial, but only when you buy with the right knowledge.

As procurement agents, Hutnia reviews 5-axis listings on Maschinensucher, Surplex and in direct insolvency liquidations every day. Below we share the criteria we apply to every transaction.

Kinematics: Trunnion, Head/Table or Head/Head?

The kinematic configuration defines the machining envelope and long-term stability of the machine.

Trunnion (table/table) — e.g. Hermle C 22 U, DMG Mori DMU 50. A and C axes are realized via a swivel rotary table. Excellent rigidity but limited workpiece size. Used (2015-2019): 85 000-180 000 EUR.

Head/table — e.g. DMG Mori DMU 80 P duoBLOCK, Mazak Variaxis i-600. B axis in the head, C axis in the table. Larger workpieces possible, higher price. Used: 140 000-320 000 EUR.

Head/head — gantry solutions (Waldrich Coburg, FPT). Rarely available second-hand, prices above 400 000 EUR. Too specialized for most job shops.

Rule of thumb: for workpieces up to 500 mm, a trunnion configuration is sufficient and cheaper to maintain. Above 800 mm, look at head/table machines.

Control: Heidenhain TNC 640 vs. Siemens 840D sl

The control is the second most important factor after kinematics. Two systems dominate the used 5-axis market:

Heidenhain TNC 640 (and the newer TNC7) — standard on Hermle, Grob, Heller. Conversational programming, cycle machining, intuitive 3D simulation. Spare parts: control electronics module approx. 8 000-12 000 EUR as exchange unit.

Siemens Sinumerik 840D sl — standard on DMG Mori, optional on Mazak and Okuma. ShopMill interface, ISO/G-code. NCU module: 6 000-10 000 EUR.

Machines with Fanuc 31i-B5 (Mazak, Makino) are less common on the German market but attractively priced — high Asian adoption pushes European used prices down by 10-15 %.

Bottom line: the control must match your team's skills and your CAM software. Retrofitting a different control on a used machine costs 25 000-40 000 EUR plus downtime — usually uneconomical.

Spindle: Operating Hours and Measurement Protocols

The spindle is the heart of any 5-axis machine. Replacing an HSK-A63 spindle on a Hermle costs 12 000-18 000 EUR (parts + labor). That is why we require the following at every inspection:

• Spindle hour counter — below 15 000 h is good condition, 15 000-25 000 h requires price negotiation, above 25 000 h a revision or replacement is necessary.
• Runout measurement protocol — acceptable radial runout on HSK-A63: max 0.003 mm. Values above 0.005 mm indicate worn bearings.
• Thermal test — 30 min warm-up under load with deviation measurement. Drift above 0.015 mm signals cooling system issues.

If the seller cannot provide a measurement protocol, that is a warning sign. Hutnia arranges an independent measurement by a certified technician for every transaction above 50 000 EUR.

Additional Equipment: What Adds Value?

Not every factory option retains its value on the used market. These features increase real value:

• Tool magazine 60+ pockets — standard is 30-40. Extended magazine (HSK-A63, double chain): +5 000-10 000 EUR value.
• Laser tool measurement (Blum, Renishaw) — saves setup time. Worth 3 000-5 000 EUR.
• Touch probe Renishaw OMP60 — if functional: +4 000-7 000 EUR.
• Through-spindle coolant (TSC) — 70 bar minimum for steel machining. Without TSC, the machine loses 15-20 % of its value.
• Oil mist separator — mandatory in many countries. Retrofit cost: 3 000-6 000 EUR.

Features that do not significantly increase value: pallet pool (if automation is not needed), additional table axes (rarely utilized in practice).

Common Pitfalls When Buying from Germany

From Hutnia's experience — the most frequent mistakes foreign buyers make:

1. No geometry verification — a laser measurement (Renishaw XL-80 or API) costs 800-1 500 EUR but reveals linear guide wear. Guide replacement (THK/Rexroth) on the X axis of a DMU 80: 18 000-25 000 EUR.

2. Underestimated transport costs — a DMU 80 class 5-axis machine weighs 8-12 t. Lowloader transport from Bavaria to Poland: 2 500-4 000 EUR. Dismounting the swivel table and securing axes: additional 1 500-2 500 EUR. Total: 4 000-6 500 EUR that buyers frequently overlook.

3. Buying a post-crash machine — hidden head damage after a collision can cost 30 000-80 000 EUR. We always ask for crash history and check the control alarm logs (Heidenhain stores the last 10 000 events).

4. Missing CE documentation — machines manufactured before 2006 may lack full documentation per Machinery Directive 2006/42/EC. Compliance retrofit: 3 000-8 000 EUR (audit + guard modifications).
