Granite Surface Plate Calibration Now Available Across 7 Midwest States

ISO/IEC 17025 Accredited On-Site Calibration, Wet Lap Resurfacing, and NIST-Traceable Certification Now Scheduling at Manufacturing Facilities Across IL, WI, IN, MI, IA, MO, and MN

Chicago, IL - Surface Plate Calibration Pros (https://surface-plate-calibration.com) has launched, making on-site granite surface plate calibration, wet lap resurfacing, and ISO/IEC 17025 accredited certification available to manufacturing facilities across Illinois, Wisconsin, Indiana, Michigan, Iowa, Missouri, and Minnesota.

The service addresses a persistent challenge in Midwest manufacturing: maintaining the flatness and accuracy of granite surface plates - the precision measurement foundation used in quality control, inspection, and certification processes across aerospace, automotive, medical manufacturing, and defense industries.

On-Site Calibration Eliminates Shipping and Downtime

Granite surface plates can weigh thousands of pounds, making off-site calibration expensive and impractical. Through Surface Plate Calibration, the entire process - cleaning, surface mapping, wet lap resurfacing, and certification - is performed directly on the shop floor. Calibration data and certificates are documented on-site the same day, minimizing production downtime and keeping facilities audit-ready.

Every calibration is performed using Hilger-Watts autocollimators and the Moody Method in a standardized Union Jack pattern, capturing flatness measurements across all axes. When plates are found out of tolerance, the wet lap resurfacing method is used to restore Grade AA, A, or B flatness per Federal Specification GGG-P-463c - without generating the airborne silica dust associated with dry lapping techniques.

"Precision measurement is the foundation of quality control in manufacturing," said Zach, founder of Surface Plate Calibration. "When a granite surface plate drifts out of tolerance, every measurement taken on it becomes suspect. The goal is to make sure that facilities across the Midwest have access to accredited, traceable calibration performed on-site by people who know what they are doing."

ISO/IEC 17025 Accreditation and NIST Traceability

All calibration work is ISO/IEC 17025 accredited through A2LA or ANAB, with NIST-traceable measurement results documented on every certificate. This level of accreditation satisfies audit requirements for ISO 9001, AS9100, and other quality management standards required across aerospace, automotive,
defense, and medical manufacturing sectors.

Each technician performing the work is individually A2LA-certified - meaning personal competencies, instruments, and calibration methods have been independently verified and accredited. Measurement uncertainty is reported on every certificate, providing the depth of documentation that auditors and
quality managers require.

Serving 7 States and 39 Metro Areas

Surface Plate Calibration currently covers 39 cities (https://surface-plate-calibration.com/services/) across the Midwest, including major manufacturing hubs in Chicago, Milwaukee, Indianapolis, Grand Rapids, Des Moines, St. Louis, and Minneapolis. Service areas span the full industrial corridor from Minnesota through Missouri, covering facilities of all sizes - from machine shops running a single plate to large-scale operations maintaining dozens of granite assets.

Appointments are typically scheduled within 5 business days, with emergency and urgent scheduling available for facilities facing audit deadlines or equipment concerns.
