High-precision metrology and dimensional inspection
ZEDCE Metrology: The Backbone of Quality
At ZEDCE, metrology is not an auxiliary service; it is the backbone of our quality. Every part that leaves our workshops undergoes a level of inspection tailored to the client's needs, ranging from simple calipers to coordinate measuring machines.
Manual Measurements
For routine production checks, our operators use 3D machines, snap gauges, micrometers, dial indicators, thread plugs, and pneumatic inspection systems.
These in-process checks ensure the required quality levels are met.
The result: less scrap, maintained tolerances, and secure production.

Coordinate Measuring Machine
With CMM, precision becomes measurable, repeatable, and controlled.
‍
For all types of parts and tight tolerances, we use coordinate measuring machines (CMM) from:
-Mitutoyo Strato-Apex 574, with a measurement uncertainty of ±0.7µm
-Mitutoyo Crysta-Apex 574, with a measurement uncertainty of ±1.7µm
-Mitutoyo Strato-Apex 7106, with a measurement uncertainty of ±0.9µm
This is the key tool for components in the aerospace, medical, automotive, defense, and robotics sectors, as well as any parts with high functional requirements.
Contour Measuring Machine
It is the ideal tool for analyzing radii, angles, complex shapes, and profile deviations.
ZEDCE uses contour measuring machines to inspect surface finish and functional geometry, ensuring the reliability of critical parts (sealing, guidance, friction) before delivery.
Our metrology department includes:
‍
-Mitutoyo Contracer C-3200
-Mitutoyo Formtracer Avant C-3200
-Mitutoyo Contracer C-4500
Used to measure profiles, radii, chamfers, and grooves as required.
If you are looking for a subcontractor capable of precisely documenting your profile requirements, ZEDCE’s contour measurement services ensure compliance from the very first parts and minimize the risk of non-conformity in production runs.

Surface finish measurement
ZEDCE performs surface finish measurement to validate that a part is not only "within tolerance" but also compliant regarding the factors that drive real-world performance: friction, sealing, noise/vibration, and long-term durability.
Depending on the function of the inspected area, we monitor roughness criteria (e.g., Ra/Rz) and, if necessary, profiles (radii) to document compliance in the quality file and secure both initial parts and series production.
This metrology and traceability approach reduces non-compliance risks and ensures reliable assemblies for high-demand parts (hydraulics, engine components, high-precision applications, robotics, medical, vacuum technology).
Our measurement equipment includes 2 high-performance machines:
‍
-Form Talysurf Laser (Taylor Hobson): Laser profilometer for measuring roughness/form/contour (including included angle) with measurement possible in the normal direction, resolution up to 0.3 nm, and form precision < 0.20 µm.
Form measurement
ZEDCE performs form measurement to verify that a part's actual geometry corresponds to its function (circularity, harmonics, straightness, coaxiality, etc.).
Our measurement equipment includes 3 high-performance devices:
‍
-Talyrond 585H Pro (Taylor Hobson): Radial precision for this Talyrond range is ± 0.01 µm.
-Talyrond 290
-Talyrond 265

Non-contact measurement
ZEDCE offers non-contact measurement to quickly check sensitive dimensions and geometries without marking the part, while ensuring excellent repeatability.
This approach relies primarily on industrial vision (optical inspection) for flatness.
Non-contact measurement is particularly relevant for fragile parts that require high precision and speed.
We use an Altisurf 500 station: Z-axis resolution stated at < 2 nm.
ISO 16232 cleanliness testing
ZEDCE performs cleanliness tests to ensure that a part is delivered free of critical contaminants (residual chips, particles, process-related traces), thereby securing assembly, reliability, and quality compliance. This approach is part of a rigorous final inspection process.
In the most sensitive sectors (particularly medical, automotive, vacuum technology, etc.), cleanliness becomes a functional criterion in its own right and is part of enhanced control and monitoring requirements.
At ZEDCE, we have a dedicated cleanliness laboratory:
-Dedicated washing tank
-Controlled-flow rinsing pump
-Desiccator
-Analytical balance ± 0.01 mg (for gravimetric analysis)
-Scanner + software for particle counting.

Hardness, structure, and defect detection
ZEDCE integrates hardness testing into its quality control process to verify that a part possesses the expected mechanical properties following material selection and/or heat treatment.
This inspection helps ensure wear resistance and fatigue strength.
To guarantee part compliance and reliability, we perform:
-Magnetic particle inspection: Detection of surface cracks invisible to the naked eye.
‍
-Hardness testing: HRC for overall validation, Vickers for detailed analysis and treated layers, and Brinell when necessary.
‍
-Nital etch test (or chemical test): Identification of tempering or softened zones.

By combining manual measurements, CMM, hardness testing, surface finish analysis, non-contact measurement, and cleanliness testing, ZEDCE offers comprehensive dimensional control, from operator checks to detailed metrological reports.
This high standard reduces uncertainty: we invest in the right tools and inspect at the right time to maintain micron-level tolerances consistently for parts destined for the automotive, aerospace, hydraulic, or medical industries.
