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.
"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!"
"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..."

Founder
Larry's journey from machine operator to calibration service founder gives him a unique perspective that goes far beyond equipment maintenance. Having operated CNC machines firsthand, he understands the real-world production challenges manufacturers face daily—the frustration of unexpected downtime, the cost of scrap from axis errors, and the pressure to maintain tight tolerances. This operator-level experience drives his approach to calibration: it's not just about verifying numbers, it's about delivering solutions that genuinely increase production quality and efficiency. Larry built Sarkinen Calibrating on the principle that precision calibration should eliminate problems before they disrupt operations, providing manufacturers with the confidence that their equipment will perform exactly as promised. His hands-on background means he approaches every calibration with practical insight into how machine accuracy directly impacts your production floor, helping you achieve highly predictable operation with minimal disruption.
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.
