Flatness Verification
Precise measurement of surface plate flatness using advanced techniques including Moody Plot analysis to ensure your reference surface meets required tolerance specifications and provides accurate measurement results.
Surface plates are the foundation of accurate inspection and layout work in precision manufacturing. Over time, wear and environmental factors affect flatness and reliability, compromising measurement integrity. Sarkinen Calibrating delivers expert surface plate leveling, flatness verification, and Moody Plot analysis to restore and maintain the reference accuracy your operations depend on—keeping your inspection results consistent and your production quality high.

Comprehensive solutions to maintain surface plate accuracy and extend the life of your precision reference surfaces.
Precise measurement of surface plate flatness using advanced techniques including Moody Plot analysis to ensure your reference surface meets required tolerance specifications and provides accurate measurement results.
Expert leveling services to establish proper orientation and eliminate angular deviations that compromise measurement accuracy. Proper leveling ensures consistent reference plane performance across the entire surface.
Thorough evaluation of surface plate condition to identify wear patterns, damage, and accuracy degradation. Our assessment provides clear documentation of current performance and recommendations for maintenance or restoration.
Surface plates naturally wear over time, and even minor deviations in flatness can significantly impact part accuracy and measurement reliability. Sarkinen Calibrating provides comprehensive surface plate maintenance that goes beyond basic verification. We evaluate flatness using Moody Plot analysis, perform precision leveling, and document surface condition to ensure your inspection reference remains dependable. With measurements traceable to NIST and International Standards, we help Portland and SW Washington manufacturers maintain the measurement integrity their quality processes demand.

Founder
Larry's journey from machine operator to calibration service founder gives him a unique perspective that goes far beyond equipment maintenance. Having operated CNC machines firsthand, he understands the real-world production challenges manufacturers face daily—the frustration of unexpected downtime, the cost of scrap from axis errors, and the pressure to maintain tight tolerances. This operator-level experience drives his approach to calibration: it's not just about verifying numbers, it's about delivering solutions that genuinely increase production quality and efficiency. Larry built Sarkinen Calibrating on the principle that precision calibration should eliminate problems before they disrupt operations, providing manufacturers with the confidence that their equipment will perform exactly as promised. His hands-on background means he approaches every calibration with practical insight into how machine accuracy directly impacts your production floor, helping you achieve highly predictable operation with minimal disruption.
Calibration frequency depends on usage intensity and criticality of measurements. High-volume inspection environments typically require annual calibration, while less frequently used plates may be calibrated every 2-3 years. ISO standards and customer requirements may dictate specific intervals.
