Surface Plate Calibration Pros has launched, making on-site granite surface plate calibration, wet lap resurfacing, and ISO/IEC 17025 accredited certification available to manufacturing companies across Illinois, Wisconsin, Indiana, Michigan, Iowa, Missouri, and Minnesota. Through the service, NIST-traceable calibration and certification are available directly at each facility, eliminating the need to ship heavy granite surface plates off-site and keeping production schedules on track.

Why it matters

Granite surface plates are the foundation of quality control in aerospace, automotive, defense, and medical manufacturing. Over time, everyday wear from tools, instruments, and equipment degrades plate flatness, putting every precision measurement and inspection process at risk. Because plates can weigh thousands of pounds, off-site calibration is both expensive and impractical. Through Surface Plate Calibration Pros, the entire process—cleaning, surface mapping, wet lap resurfacing, and accredited certification—is performed directly on the shop floor.

The details

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

  • Surface Plate Calibration Pros launched in February 2026.

What they’re saying

“Precision measurement is the foundation of quality control in manufacturing. The guys who run machine shops, manage quality for aerospace companies, or oversee defense contracts—they need to know their surface plates are traceable, accredited, and calibrated by people who know what they're doing.”

— Zach, Founder (EINPresswire.com)

The takeaway

Surface Plate Calibration Pros is providing a critical service to Midwest manufacturers by offering on-site granite surface plate calibration, resurfacing, and accredited certification, eliminating the need for costly and impractical off-site calibration and keeping production schedules on track.
