Precision calibration services that keep your CNC machines, surface plates, and rotary equipment performing to exact specifications. Sarkinen Calibrating delivers NIST-traceable accuracy to 1.0 parts per million, helping Portland OR and SW Washington manufacturers minimize unexpected downtime, maintain production quality, and verify equipment meets promised specifications. Founded by a former machine operator who understands real production challenges.
Comprehensive calibration solutions from linear accuracy to rotary positioning, all traceable to NIST standards with faster local response times.
Verify precision to 1.0 part per million using Renishaw's Laser Interferometer. Measure positioning accuracy, repeatability, straightness, and squareness across full axis travel to ensure new machines meet warranty specifications and identify shipping or installation errors.
Fast machine health evaluation using Renishaw's QC20-W Ballbar. Identifies backlash, servo mismatch, axis reversal errors, and squareness problems. Ideal for validating service work and troubleshooting accuracy issues with minimal downtime.
Expert leveling and flatness verification including Moody Plot measurement. Maintain accurate reference planes for inspection and layout work, ensuring part accuracy and measurement reliability as surface plates wear over time.
Verify angular positioning accuracy and repeatability using Renishaw's Rotary Calibration System. Identify mechanical wear, setup errors, or encoder issues affecting multi-axis machining before they impact production quality.
Detect and correct pitch and roll errors using Mahr-Federal's Electronic Level. Evaluate machine beds, guideways, and structures where angular deviations affect accuracy, especially after installation, relocation, or foundation movement.
Hands-on training for laser interferometry, ballbar systems, CAM software, and CNC operation. Tailored instruction helps maintenance teams and quality engineers perform in-house diagnostics and understand machine accuracy data.
Manufacturing precision depends on equipment that performs exactly as programmed. Sarkinen Calibrating provides measurements that exceed the required 10:1 ratio for proper calibration, with accuracy to 1.0 parts per million—fully traceable to NIST and International Standards. Founded by a former machine operator, we understand that calibration isn't just equipment maintenance; it's about preventing unexpected downtime, eliminating adjustment cycles, and delivering proof to your customers that machines can perform as promised, every time.
Delivering predictable, accurate calibration services that keep production running smoothly across the Pacific Northwest.
"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..."
"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"
"This guy knows his stuff. Would definately recommend! Friendly good people!"

Founder
Larry started his career as a machine operator on the production floor, where he experienced firsthand the frustrations of equipment failures and unexpected downtime. That hands-on experience shaped his perspective that calibration should be more than routine equipment maintenance—it should be a strategic solution that increases production quality and operational efficiency. After years of operating machines and understanding what manufacturers truly need, Larry founded Sarkinen Calibrating to deliver precision services from an operator's perspective. His approach focuses on preventing problems before they disrupt production, verifying that equipment performs exactly as promised, and providing manufacturers with the confidence that their machines will deliver consistent accuracy. Under Larry's leadership, Sarkinen Calibrating has grown to serve the Portland OR and SW Washington area with NIST-traceable calibration services, while maintaining the responsive, customer-focused service that comes from understanding production realities.
What does NIST-traceable calibration mean?
NIST-traceable calibration means our measurements are directly linked to standards maintained by the National Institute of Standards and Technology through an unbroken chain of comparisons. This provides legal proof that your equipment meets specified accuracy requirements and ensures measurements are recognized internationally for quality compliance.
