Washington's aerospace, manufacturing, and precision machining sectors demand exacting standards. Sarkinen Calibrating delivers NIST-traceable CNC calibration services throughout SW Washington and the Greater Portland area, ensuring your equipment meets specification and operates predictably. From laser interferometry to ballbar testing, we minimize unexpected downtime and maximize production quality with faster response times than out-of-area providers.
Comprehensive machine accuracy verification using industry-leading Renishaw and Mahr-Federal systems, all with measurements traceable to NIST and International Standards.
Verify positioning accuracy to 1.0 parts per million using laser interferometry. Full linear axis measurement for positioning accuracy, repeatability, straightness, and squareness ensures your machine meets manufacturer specifications and maintains production quality standards.
Fast machine health assessment using Renishaw's QC20-W Ballbar to evaluate circularity and identify backlash, servo mismatch, axis reversal errors, and squareness problems. Ideal for validating service work and troubleshooting accuracy issues.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's Rotary Calibration System. Identifies mechanical wear, setup errors, and encoder issues affecting multi-axis machining performance.
Expert leveling and flatness measurement using Moody Plot methodology ensures your surface plates provide accurate reference planes for inspection and layout work. Maintains measurement consistency and reliability in production environments.
Detect pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal's Electronic Level. Identifies alignment issues from installation, relocation, or foundation movement that affect machining stability.
Hands-on training for CAM software, CNC operation, and Renishaw calibration equipment. Tailored sessions help operators, programmers, and technicians improve efficiency, reduce errors, and perform in-house diagnostics with confidence.

Experience-driven calibration service built from the machine floor up.
Founder
Larry's journey into precision calibration began on the machine floor, where he worked as a machine operator and saw firsthand how equipment accuracy directly impacts production quality and efficiency. Frustrated by unexpected downtime and the limitations of traditional calibration approaches that focused only on equipment maintenance, Larry founded Sarkinen Calibrating with a different philosophy: calibration should be a comprehensive solution that keeps operations running predictably. His operator's perspective drives the company's focus on practical, results-oriented service. Larry understands production schedules, quality pressures, and the real cost of machine inaccuracy. This background shapes every aspect of Sarkinen Calibrating's service delivery—from flexible scheduling that minimizes disruption to detailed reporting that helps customers prove their machines deliver as promised. Under Larry's leadership, Sarkinen Calibrating has become the trusted local calibration partner for Washington and Portland-area manufacturing facilities seeking NIST-traceable accuracy delivered by professionals who truly understand production operations.
Why is CNC machine calibration necessary?
CNC machines lose accuracy over time due to normal wear, thermal changes, mechanical drift, and component aging. Regular calibration verifies that your machine still meets manufacturer specifications and identifies issues before they affect part quality. Calibration is especially critical after machine relocation, major repairs, or when producing high-precision components.
