Precise definitions and conditions that govern our metrology services and product specifications.
Our reported sub-nanometer values refer to the arithmetic mean roughness (Ra) measured over a 0.8 mm cutoff length on titanium alloy surfaces. The measurement is performed under controlled lab conditions (20 °C ± 1 °C, 45 % RH) using our White Light Interferometry System. Results may vary by up to ±0.3 nm on parts with complex curvature or high-aspect-ratio features.
All roughness topography mapping reports comply with ASME B46.1-2019 for surface texture parameters (Ra, Rz, Rq, Rsk, Rku) and ASME B89.4.22 for the interferometric measurement system itself. We do not certify compliance with ASME Y14.5 for geometric dimensioning and tolerancing unless explicitly requested as a separate service.
Our micro-honing process is validated for Ti-6Al-4V (Grade 5), Ti-6Al-4V ELI (Grade 23), and Ti-3Al-2.5V (Grade 9). For other titanium alloys, including beta‑titanium or high‑interstitial grades, we require a preliminary feasibility test on a sample coupon (minimum 25 mm × 25 mm). The test cost is credited toward the first production batch.
Standard turnaround is 10 business days from receipt of parts and signed service agreement. Expedited service (5 business days) is available at a 40 % surcharge. Both timelines exclude shipping. We do not guarantee specific finish values on parts with pre-existing surface damage deeper than 2 µm.
For polished titanium or other high-reflectivity surfaces, our system automatically reduces the exposure time and applies an anti‑bloom filter. The combined measurement uncertainty (k=2) is ±1.2 nm for Ra values below 10 nm. If the surface reflectivity exceeds 85 %, we recommend applying a thin anti‑reflective coating or using our optional dark‑field measurement mode.
The software suite accepts data in CSV, TXT, and proprietary .WLI formats. Import adapters for Zygo, Bruker, and Polytec instruments are included. For other systems, we provide a free data‑conversion tool upon request. The suite does not support real‑time streaming from non‑PrecisionMet hardware.
Real feedback from engineers and quality managers who rely on sub-nanometer precision for critical joints.

Certified traceability for regulated industriesStraight answers about white light interferometry, micro-honing, and roughness mapping for titanium alloys and precision metal interfaces under ASME compliance.
Our system resolves sub-nanometer vertical features, typically from 0.1 nm up to several millimeters in step height. It handles roughness Ra values from below 1 nm to 10 µm on high-strength titanium alloys and polished metal interfaces, meeting ASME B46.1 requirements for both fine and coarse textures.
Micro-honing uses controlled abrasive media to remove microscopic peaks and valleys on bearing surfaces. By achieving a consistent plateau finish with controlled oil-retention valleys, we lower the coefficient of friction by up to 40% compared to ground or turned surfaces. This directly reduces wear in high-cycle cinematic joints made of Ti-6Al-4V or similar alloys.
Yes. Every micro-honing service includes pre- and post-process 3D surface maps generated by our white light interferometer. The maps show Ra, Rz, Rq, and bearing ratio curves. We deliver a compliance report that compares your part against ASME B46.1 or customer-specified tolerances.
For a standard batch of 50 precision titanium components (e.g., actuator pins or implant stems), we complete micro-honing and full topography mapping within 5 business days. Rush orders with partial batches can be finished in 2 days. Each part is individually measured and documented.
Yes. Our white light interferometry head can be tilted and translated to follow complex geometries. We routinely measure spherical, aspheric, and freeform surfaces on titanium and stainless steel parts. The software stitches multiple overlapping scans to create a unified topography map of the entire interface.
We use automated measurement sequences with fixed illumination settings, stage positioning, and analysis filters. The system prompts the operator only to load the part and confirm alignment. Repeatability tests on a single titanium reference show Ra variation below 0.5 nm across 20 consecutive measurements by three different technicians.
