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.
