Maintain inspection accuracy and measurement reliability with professional granite surface plate calibration services throughout Northern California. Sarkinen Calibrating provides NIST-traceable flatness verification, expert leveling, and comprehensive condition evaluation to ensure your surface plates continue delivering precision reference planes. Our region-specific service minimizes downtime with faster response times than distant providers, helping Bay Area and Northern California manufacturers maintain the measurement consistency critical for quality production.
Comprehensive calibration solutions ensuring your surface plates maintain accuracy and reliability for critical inspection and layout work.
Precise flatness measurement using Moody Plot analysis to verify your surface plate maintains proper reference plane geometry. NIST-traceable measurements identify wear patterns and accuracy drift before they compromise part quality.
Professional leveling services ensure your surface plate provides a true horizontal reference. Proper leveling eliminates errors caused by foundation movement, relocation, or installation issues that affect measurement consistency.
Thorough assessment of surface plate condition including wear analysis, damage detection, and accuracy certification. Comprehensive reporting helps you plan maintenance and replacement cycles to maintain inspection confidence.
Surface plates are the foundation of dimensional inspection—when they lose accuracy, every measurement becomes suspect. Sarkinen Calibrating provides expert granite surface plate calibration throughout Northern California, using precision measurement equipment to verify flatness and proper leveling. As surface plates wear from daily use, undetected accuracy drift can compromise production quality and create costly scrap. Our calibration service identifies these changes early, providing documented proof that your reference planes meet specifications. With faster regional response times and comprehensive reporting, we help Bay Area manufacturers maintain the measurement reliability that quality production demands.
Northern California companies rely on our calibration expertise to maintain measurement 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"
"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 with a unique perspective—he started as a machine operator before building a calibration service business. For Larry, calibration has never been just about equipment maintenance and checking off compliance boxes. It's about understanding real machining operations from the operator's perspective and providing practical solutions that genuinely increase production quality and efficiency. This hands-on background allows him to see calibration challenges the way his customers do—as critical factors affecting daily production, part accuracy, and customer confidence. Larry built Sarkinen Calibrating to serve Northern California manufacturers with the kind of calibration service he wished existed when he was running machines: responsive, knowledgeable, and focused on minimizing disruption while maximizing accuracy. His approach combines technical precision with operational practicality, helping customers maintain equipment accuracy without unnecessary downtime or complexity.
How often should a granite surface plate be calibrated?
Industry standards typically recommend annual calibration for most production environments, though high-use facilities may require semi-annual or quarterly calibration. Frequency depends on usage intensity, criticality of measurements, and whether you're meeting customer quality requirements or ISO compliance. We can help establish an appropriate calibration schedule based on your specific operational needs.
