Buying used Zeiss coordinate measuring machines gives production departments fast access to high-precision metrology without new machine budgets. You gain calibrated performance for quality control and reverse engineering while reducing environmental impact.
This guide covers key models, pricing factors, reliability checks, and what to verify before a purchase. You can use the summary table to compare leading options at a glance.
| Model | Measuring Range (mm) | Max Speed (mm/s) | Sensor Type | Used Price Range (USD) |
|---|---|---|---|---|
| Zeiss CONTURA G2 | 500 x 1000 x 700 | 600 | Touch probe + 5-axis scanning | 110,000–180,000 |
| Zeiss COMET L3D | 250 x 250 x 200 | N/A | Structured blue light | 35,000–60,000 |
| Zeiss PRISMO plus | 1000 x 2000 x 1000 | 400 | Touch probe with scanning options | 200,000–350,000 |
| Zeiss METROTOM 1500 | 1500 x 1000 x 1200 | 500 | CT scanning + probing | 280,000–450,000 |
Understanding the Used Market for Zeiss CMMs
The secondary market for Zeiss coordinate measuring machines is active because many plants upgrade optics and controllers while well-maintained frames remain serviceable. You will find entry-level scanning arms and large bridge CMMs, each suited to different volume and tolerance needs.
Price depends on measuring range, sensor capability, year of manufacture, and local service availability. Target machines with full service history, original calibration logs, and current controller software to reduce integration risk.
Evaluating Accuracy and Performance Specifications
Accuracy figures on used Zeiss CMMs vary with length, temperature stability, and probe system. Always request single-point length measurement uncertainty and volumetric probing error (VPE) values rather than generic lab figures.
Check air-bearing condition, linear encoders, and compensation tables, because worn air filters or uneven floors can shift results beyond stated tolerances in daily use.
Inspection and Servicing Before Purchase
Pre-purchase verification reduces surprises and supports fair pricing. Arrange on-site validation or a short trial run with your parts to confirm repeatability, probe compatibility, and controller responsiveness.
- Review service records and hours on air and linear encoders.
- Inspect guideways, bearings, and air supply for leaks or pressure drops.
- Verify controller I/O, software licenses, and available spare parts.
- Run geometric accuracy tests with gauges or sphere arrays to match reported specs.
Integration, Software, and Support Considerations
Older Zeiss controllers may need updated drivers or network setup to fit current QA environments. Confirm that the software version on the machine supports your CAD formats, scripting needs, and data exchange workflows.
Factor in local service agreements, training for operators, and lead times for replacement probes or electronics to keep the line moving after installation.
Final Recommendations for Selecting Used Zeiss Coordinate Measuring Machines
Use structured checks and real-part validation to align machine capability with your quality goals and budget constraints.
- Define your tolerance, part size, and throughput requirements before shortlisting models.
- Verify accuracy with calibrated artifacts and document measured uncertainty.
- Inspect mechanical condition, encoder health, and air-bearing performance on-site.
- Confirm controller specs, software support, and available service options to protect your investment.
FAQ
Reader questions
What measuring range and accuracy should I look for in a used Zeiss CMM for small precision parts?
For small precision parts, a model like the CONTURA G2 with 500 x 1000 x 700 mm range and sub-3 µm single-point accuracy is often sufficient, provided the machine has recent calibration and probing error within your process tolerance.
How can I verify that a used Zeiss COMET L3D structured light scanner is still reliable?
Run scan checks on spheres or stepped targets, compare repeatability across multiple positions, and validate software version compatibility with your CAD and reporting tools before committing to the purchase.
What should I check regarding the controller and software when buying a used Zeuss metrology machine?
Confirm controller model, available memory, I/O configuration, current software patches, and license status to avoid integration delays and ensure support for your existing NC routines and reporting systems.
Are large bridge CMMs like the Zeiss PRISMO plus a good fit for low-volume, high-mix production?
Yes, if your parts justify the larger footprint and investment; the PRISMO plus offers long measuring range, heavy load capacity, and flexible probing, but you should confirm service history and floor layout compatibility first.
