Eliminate unexpected downtime and maintain production quality with precision CNC calibration services built for accuracy. Our NIST-traceable measurements detect alignment errors, mechanical wear, and accuracy drift before they impact your parts. From laser interferometry to ballbar testing, we deliver comprehensive diagnostics that keep your machining operations predictable, efficient, and producing to specification every time.
Comprehensive precision measurement solutions to verify machine accuracy, identify wear patterns, and maintain production quality across your entire facility.
Verify linear axis positioning with NIST-traceable accuracy to 1.0 parts per million. Measure positioning accuracy, repeatability, straightness, and squareness across full travel to detect shipping damage, installation errors, or specification deviations before production impact.
Fast evaluation of machine health using wireless ballbar technology. Identify backlash, servo mismatch, axis reversal errors, and squareness problems. Validate service work, troubleshoot accuracy issues, and support maintenance planning with repeatable circularity diagnostics.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions. Verify proper installation and ongoing calibration to prevent multi-axis machining errors caused by mechanical wear, setup problems, or encoder drift.
Maintain reference plane accuracy through expert leveling and flatness verification with Moody Plot analysis. Ensure consistent inspection results as plates wear over time, preserving measurement reliability and part acceptance confidence for layout work.
Detect pitch and roll errors in machine beds, guideways, and large structures using precision electronic levels. Identify alignment issues from installation, relocation, or foundation movement that affect axis geometry and machining stability.
Hands-on instruction for laser interferometry, ballbar systems, CAM software, and CNC operation. Tailored to your equipment and skill level, empowering teams to perform in-house diagnostics, interpret accuracy data, and maximize machine capability.
Manufacturing success depends on machines that deliver consistent, predictable accuracy. Our comprehensive calibration services go beyond routine maintenance to provide actionable insights into machine health. Using advanced laser interferometry and wireless ballbar technology, we measure positioning accuracy, detect hidden wear patterns, and verify alignment across every critical axis. Each measurement is traceable to NIST standards and exceeds the required 10:1 calibration ratio. Whether validating new equipment under warranty or maintaining production machines, our diagnostics identify problems before they affect part quality, helping Portland-area manufacturers minimize adjustments, eliminate unexpected failures, and maintain customer confidence.
Manufacturing facilities across the region rely on our precision calibration to maintain quality and reduce downtime.
"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 didn't start in calibration—he started on the shop floor as a machine operator, running the equipment that manufactures depend on every day. That hands-on experience shaped how he built Sarkinen Calibrating: not as just another metrology service, but as a partner who understands what keeps production moving and what shuts it down. For Larry, calibration has always been about more than maintaining equipment to specification. It's about looking at the entire machining operation and delivering solutions that increase production quality, eliminate unexpected downtime, and give manufacturing teams confidence in their output. He built Sarkinen Calibrating to serve Portland OR and SW Washington with faster response times and a practical, operator-focused approach to precision measurement. His goal remains simple: provide the best customer service possible while helping manufacturers run predictable, efficient operations that deliver accurate parts every time.
Local calibration service with faster response times for Portland OR and SW Washington, plus extended service availability.
