Maintain precision inspection and layout accuracy with professional surface plate calibration throughout Oregon. Sarkinen Calibrating provides expert leveling, flatness verification, and Moody Plot analysis to ensure your granite and cast iron surface plates deliver consistent reference planes. Our NIST-traceable measurements address Oregon's diverse manufacturing environment, from moisture-sensitive aerospace facilities to demanding machine shop operations requiring reliable measurement standards.
Comprehensive calibration solutions to maintain measurement accuracy and confidence in your inspection results.
Expert flatness measurement using Moody Plot analysis to verify your surface plate maintains proper reference plane accuracy. We evaluate condition and wear patterns to ensure continued measurement reliability for precision inspection and layout work.
Professional leveling services to restore and maintain optimal surface plate performance. Proper leveling eliminates angular errors that compound across measurement operations, ensuring consistent results and extended plate service life.
NIST-traceable verification confirming your surface plate meets Grade A or Grade B specifications. Detailed certification documentation supports quality audits and validates measurement system capability for production and inspection environments.
Surface plates wear over time, and even minor flatness deviations can significantly compromise part accuracy and inspection confidence. Sarkinen Calibrating's expert calibration service evaluates your surface plate condition, verifies flatness with precision Moody Plot analysis, and ensures proper leveling. Our measurements are fully traceable to NIST standards, providing the documentation you need for quality audits while maintaining the reference plane accuracy critical for Oregon's precision manufacturing operations. With local service throughout Portland, SW Washington, and Oregon, we deliver faster response times and minimize disruption to your measurement operations.
Delivering precision calibration and reliable measurement solutions for production facilities across the Pacific Northwest.
"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"
"This guy knows his stuff. Would definately recommend! Friendly good people!"
"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..."

Founder
Larry founded Sarkinen Calibrating after years of hands-on experience as a machine operator, giving him a unique perspective that goes far beyond typical equipment maintenance. He understands the daily realities of production operations and knows that calibration isn't just about meeting specifications—it's about preventing downtime, maintaining part quality, and supporting efficient manufacturing workflows. This operator-first perspective shapes every service Sarkinen Calibrating provides throughout Oregon and SW Washington. Larry built the company on the principle that calibration should deliver practical solutions that increase production quality and efficiency, not just generate paperwork. His experience troubleshooting measurement issues on the shop floor translates directly into calibration services that identify problems before they impact production. Whether verifying new equipment meets promised specifications or maintaining existing measurement standards, Larry's approach focuses on keeping Oregon manufacturing operations running accurately and predictably. That real-world foundation has made Sarkinen Calibrating the trusted choice for precision facilities throughout the Pacific Northwest.
What is the difference between Grade A and Grade B surface plate?
Grade A surface plates have tighter flatness tolerances than Grade B, making them suitable for more precise inspection work. Grade A is typically used for high-precision applications and calibration laboratories, while Grade B provides adequate accuracy for general inspection and layout operations. The grade selection depends on your measurement tolerance requirements and the level of accuracy needed for your specific manufacturing processes.
