Sarkinen Calibrating delivers NIST-traceable precision calibration services throughout Washington with accuracy to one millionth of an inch. Our founder's machine operator background means we understand production realities—not just equipment specs. We serve SW Washington manufacturers with faster local response times, comprehensive calibration solutions, and the expertise to eliminate unexpected downtime while maximizing machine accuracy and production quality.
Comprehensive machine accuracy verification and calibration solutions for Washington manufacturing operations, all traceable to NIST standards.
Laser interferometer verification of linear axis positioning accuracy, repeatability, straightness, and squareness with 1.0 PPM precision. Fully NIST-traceable measurements identify hidden damage and alignment errors before they impact production quality.
Quick circularity analysis using Renishaw QC20-W wireless ballbar to identify backlash, servo mismatch, axis reversal errors, and squareness issues. Validates service work and provides fast machine health snapshots for preventive maintenance planning.
Precision measurement of angular positioning accuracy, repeatability, and alignment for rotary tables and trunnions using Renishaw's Rotary Calibration System. Ensures multi-axis machining accuracy matches programmed commands.
Expert leveling and flatness verification including Moody Plot analysis to maintain accurate reference planes. Monitors surface plate wear to ensure consistent inspection results and measurement reliability in production environments.
Mahr-Federal electronic level detection of pitch and roll errors in machine beds, guideways, and large structures. Identifies alignment issues from installation, relocation, or foundation movement affecting machining stability.
Hands-on instruction for laser interferometry, ballbar systems, CAM software, and CNC operation. Empowers maintenance teams and quality engineers to perform in-house diagnostics and understand machine accuracy data.
Built by a former machine operator who understands production realities, Sarkinen Calibrating delivers precision calibration services that go beyond equipment maintenance. We serve Washington manufacturers with NIST-traceable measurements exceeding 10:1 calibration ratios, faster local response times than out-of-area providers, and comprehensive solutions that verify new machine warranties, troubleshoot accuracy problems, and eliminate the unexpected downtime that disrupts production schedules and customer commitments.
Washington manufacturers rely on Sarkinen Calibrating for precision calibration services that keep production running accurately.
"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"
"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..."
"This guy knows his stuff. Would definately recommend! Friendly good people!"

We combine machine operator experience with NIST-traceable precision to deliver calibration services that maximize uptime and production quality.
SW Washington service area means faster response times and more predictable scheduling than out-of-area calibration providers.
Measurements accurate to 1.0 PPM (one millionth of an inch per inch), fully traceable to NIST and International Standards.
Founded by a machine operator who understands production operations, not just equipment specifications and maintenance schedules.
Verify new machines meet manufacturer specifications while under warranty, identifying shipping damage and installation errors early.
Precision calibration services built on real production experience.
Founder
Larry didn't start in calibration—he started on the production floor as a machine operator, running equipment and understanding firsthand how machine accuracy impacts part quality, production efficiency, and customer satisfaction. That operator perspective became the foundation for Sarkinen Calibrating when Larry recognized that calibration should be more than routine equipment maintenance. It should solve real production problems. Today, Larry brings that practical manufacturing experience to every calibration service, looking beyond measurements to understand how machine performance affects operations. His approach focuses on identifying issues before they become problems, verifying that equipment delivers as promised, and helping Washington manufacturers maintain the predictable, accurate operations that keep production schedules on track and customers confident. For Larry, precision calibration isn't about equipment specs—it's about keeping production running right.
