Achieve NIST-traceable accuracy to 1.0 parts per million with our comprehensive laser calibration services. Founded by a former machine operator, Sarkinen Calibrating understands production demands and delivers calibration solutions that eliminate unexpected downtime, verify equipment specifications, and maintain consistent machining accuracy throughout Portland OR and SW Washington.
Comprehensive machine accuracy solutions using advanced laser interferometry, ballbar testing, and precision measurement systems traceable to NIST standards.
Verify precision linear axis accuracy using laser interferometry to 1.0 parts per million. Measure positioning accuracy, repeatability, straightness, and squareness across full travel with NIST-traceable results that exceed 10:1 calibration ratio requirements.
Evaluate CNC machine performance using Renishaw's QC20-W Ballbar system. Quickly identify backlash, servo mismatch, axis reversal errors, and squareness problems while validating service work and supporting maintenance planning with wireless setup.
Determine rotary axis accuracy using Renishaw's Rotary Calibration System. Measure angular positioning accuracy, repeatability, and alignment to identify mechanical wear, setup errors, or encoder issues affecting multi-axis machining performance.
Maintain surface plate consistency through expert leveling and flatness verification including Moody Plot analysis. Ensure accurate reference planes for inspection and layout work by monitoring wear and maintaining measurement reliability.
Identify and correct machine axis errors using Mahr-Federal's Electronic Level. Detect pitch and roll errors in machine beds, guideways, and large structures caused by installation, relocation, or foundation movement.
Hands-on training for laser interferometer, ballbar systems, and machine accuracy principles. Learn proper setup, data interpretation, and troubleshooting techniques tailored to your equipment and team's skill level.
Initial Equipment Assessment and Planning
We begin with a thorough evaluation of your machine tools, production requirements, and calibration history. Our team reviews equipment specifications, discusses performance concerns, and develops a customized testing plan that minimizes disruption to your Portland or SW Washington operations while addressing your specific accuracy needs.

Founder
Larry's journey into precision calibration began on the shop floor as a machine operator, giving him firsthand understanding of how equipment accuracy directly impacts production quality and efficiency. This unique perspective shaped his approach to calibration service—viewing it not merely as equipment maintenance, but as a comprehensive solution for machining operations. His operator background means he speaks your language, understands production pressures, and recognizes how unexpected downtime affects your bottom line. Larry built Sarkinen Calibrating on the principle that calibration should be predictable, minimally disruptive, and focused on preventing problems before they impact production. His commitment to customer service and operational efficiency has made Sarkinen Calibrating the trusted local calibration partner for manufacturers throughout Portland OR and SW Washington. When Larry evaluates your equipment, he sees it through the lens of someone who has operated similar machines and understands what accuracy truly means in real-world production environments.
