Productivity Quality, Inc. provides ISO/IEC 17025:2017 accredited machine tool calibration services for milling and turning CNC machine tools. Our services are traceable to NIST and comply with the ASME B5.54:2005 standard. We also can provide services compliant to Boeing CNC calibration requirements upon request. Our services include updates to CNC error compensation to improve machine performance when allowed by the CNC control. Our certifications include both “As Found” and “As Left” data and we provide a trend graph over calibration cycles to help you keep track of machine history.

The PQI Difference
PQI uses Renishaw XL-80 laser interferometers for linear, straightness, squareness, pitch and yaw analysis. The XL-80 can measure up to 80 meters in length with an accuracy of +/- 0.5 ppm and it offers resolution down to a nanometer. When used in conjunction with the XR20-W Rotary Axis calibrator we are able to offer both A and B axis rotary calibration. The XR20-W system allows us to measure rotational axis position to within 1 arc second. We also provide services to measure and correct “center of rotation” errors for 4 and 5 axis systems.
We use the Renishaw QC20-W wireless ballbar system for dynamic machine tool performance diagnosis. The ballbar has a system accuracy of +/- 1.25µm and can be set to calibration from 100 to 600mm radii. We also have the small circle kit with a 50mm radii test. Tests are performed in both clockwise and counterclockwise directions to evaluate error. Additionally, we can provide partial arc testing up to 220 degrees throughout the center pivot axis point.
Finally, when requested, we can perform a complete spindle analysis test to check for vibration, runout, spindle growth and speed with our Lion Precision spindle check system.
It’s not what’s on the front of the report, it’s what's behind it.
All we make are numbers, so they better be right. And that’s why we're measurement enthusiasts: excited when we get a new piece of equipment or a new person with different expertise in the lab. Valid measurement results are critical to manufacturing processes.
- ISO 17025 Accreditation ensures the validity of measurement results.
- Failed measurement results have consequences large and small.
- Hubble Telescope mirror distortion: A $950 million measurement error.
- Failed measurement of heart pacemaker seals: 7 Deaths, $30 million settlement.
Don’t trust the report: trust what’s behind it. Let us show you the AIS difference.
We are happy to prepare a quote for the services you require. Please provide the manufacturer and model of the machine tool, the type of control and its software version and what you would like us to do. We offer a variety of plans and would be happy to discuss how we can help.
Our services are often retained by customers for verification that a newly installed machine tool meets its performance specifications. An accredited certificate of performance provides a conclusive document on meeting performance guarantees.
These CNC install verifications can be expanded to be a component of a full IQ / OQ / PQ qualification process.

Offered AIS Services
Dimensional Inspection
AIS offers dimensional inspection services for all types of manufactured parts. First article inspections, statistical analysis, and capability and gage R&R studies are our specialties. We have over 8 contact CMMs, 6 vision and multi sensor CMMs, 3 portable arm CMMs and a laser tracker with dedicated and experienced experts running them.
CT Scanning
The use of industrial CT scanning systems for metrology is one of the most significant advancements in the industry for the past 50 years: every surface, internal and external, has complete coverage with millions of points in only a few minutes. This point gathering capability is paired with state‑of‑the‑art software to intelligently manage data and report features for fast CAD‑to‑part comparisons, GD&T, and reverse engineering.
Part Digitizing & Reverse Engineering
Part digitizing is not a “one size fits all” exercise. First, an analysis of part characteristics like surface conditions, part details, or required tolerances guides us to one of our scanning technologies: portable arm laser scanning, cabinet laser scanning, structured light, interferometry, optical focus variation and confocal laser scanning.
Surface & Form Metrology
Ever shrinking part sizes and tighter tolerances require more attention than ever to a part's surface and form characteristics. Surface and form metrology requires the ability to work in the realm of nanometers. In 2018 we created a dedicated lab space just for surface and form metrology with + / - 1 degree F temperature controls and special provisions for vibration isolation. Our lab includes contact and non-contact technologies. Our results comply with ASME and ISO standards for surface and form metrology including 3D spatial parameters for surface finish analysis.
Onsite Measurement Services
Sometimes a part is simply too big to move to an offsite inspection area or even take it off the machine that is producing it. Our portable arm, laser tracker, and laser interferometer services allow you to get accredited measurement data right at your site. Dimensional inspection including GD&T, CAD to part comparisons, reverse engineering and machine geometry checks for linear, straightness, squareness, pitch and yaw can all be completed at your site with uncertainties to .000012”.
