Maintain measurement accuracy with professional surface plate flatness verification services. Sarkinen Calibrating uses precision Moody Plot analysis to evaluate your reference surfaces, ensuring consistent inspection results and reliable dimensional control. Whether you're validating new plates or monitoring wear on critical measurement equipment, our NIST-traceable verification service helps protect part quality and prevent costly production errors before they impact your operation.
Comprehensive calibration solutions to maintain your reference surface accuracy and measurement reliability.
Expert flatness measurement using Moody Plot analysis to verify surface plate condition and ensure accurate reference planes. Evaluates wear patterns and dimensional consistency to maintain inspection reliability and support quality control operations.
Precision leveling services to establish proper surface plate orientation and support consistent measurement results. Uses electronic level technology to detect and correct pitch and roll errors that can affect dimensional inspection accuracy.
Thorough evaluation of surface plate wear, damage, and overall condition to determine if your reference surface continues to meet accuracy requirements. Identifies issues before they impact production measurement reliability and part quality.
Surface plates provide the foundation for accurate dimensional inspection, but they wear over time. Sarkinen Calibrating delivers expert flatness verification using proven Moody Plot methodology, identifying wear patterns and deviations that compromise measurement reliability. Our service ensures your reference surfaces continue to support accurate layout work and inspection operations, preventing costly quality issues. With NIST-traceable results and local service availability, we help Portland and SW Washington manufacturers maintain confidence in their measurement systems.
Join manufacturers who rely on our precision calibration to maintain inspection accuracy and production quality.
"I have worked with Mr Sarkinen on a job in Portland He is a Highly Skilled, Knowledgable Professional. I would definitely recomend him for all your Machine Tool Calibration Metrics. Sincerely Curtis Page Naughtellis CNC Service"
"As plant manager at Triad, I am always looking for ways of testing and measuring the condition of our large machines. Our outside repair tech suggested that I have Sarkinen Calibrating run their Ball Bar Test on all of our machines to show if we had any critical wear issues..."
"This guy knows his stuff. Would definately recommend! Friendly good people!"

Founder
Larry started as a machine operator before building a calibration service, so for him, it has always been more than just equipment maintenance. It's about looking at machining operations and providing solutions that will increase production quality and efficiency. His hands-on experience in production environments gives him unique insight into how surface plate accuracy and measurement reliability directly impact manufacturing operations. Larry understands that proper calibration isn't just about meeting specifications—it's about helping customers minimize downtime, eliminate unexpected quality issues, and maintain confidence in their inspection processes. This operator-first perspective shapes Sarkinen Calibrating's approach to every service, from surface plate verification to comprehensive machine calibration. Larry's commitment to customer service and practical problem-solving has helped manufacturers throughout Portland OR and SW Washington maintain accurate, predictable operations.
Do surface plates need to be calibrated?
Yes, surface plates should be regularly verified for flatness. Surface plates wear over time through normal use, and this wear can affect measurement accuracy. Regular flatness verification using Moody Plot analysis ensures your reference surface continues to provide reliable dimensional control and accurate inspection results.
How often should surface plate flatness be verified?
What is a Moody Plot and why is it used?
Can a worn surface plate be repaired or does it need replacement?
How long does surface plate flatness verification take?
What accuracy standards do your measurements meet?
Do you provide on-site surface plate verification?
What documentation do you provide after verification?
