Sarkinen Calibrating delivers NIST-traceable precision calibration services across Washington and Oregon, ensuring your CNC machines and manufacturing equipment maintain the accuracy Portland-area production demands. From laser interferometry to ballbar testing, we eliminate unexpected downtime and verify that every axis, surface plate, and rotary component performs exactly as specified—keeping your operations predictable and your parts within tolerance.
Comprehensive machine accuracy solutions from laser interferometry to electronic leveling, all NIST-traceable and designed to minimize production disruptions.
Verify CNC linear axis positioning accuracy, repeatability, straightness, and squareness using Renishaw Laser Interferometer. Measurements to 1.0 PPM ensure new machines meet warranty specs and identify hidden damage before production impact.
Rapidly evaluate CNC machine health with Renishaw QC20-W Ballbar. Identifies backlash, servo mismatch, axis reversal errors, and squareness issues. Validates service work and supports maintenance planning with minimal setup time.
Maintain reference plane accuracy through expert leveling and flatness verification using Moody Plot analysis. Monitors wear patterns to preserve inspection reliability and measurement consistency across production environments.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions. Identifies mechanical wear, encoder issues, and setup errors affecting multi-axis machining precision on modern machine tools.
Detect and correct pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal Electronic Level. Ideal for identifying alignment issues from installation, relocation, or foundation movement.
Hands-on training for CAM software, CNC operation, laser interferometer, and ballbar systems. Tailored sessions help operators, programmers, and technicians maximize machine capability and interpret calibration data effectively.
We begin with a detailed discussion of your machining operations, production requirements, and any accuracy concerns. Understanding your facility's needs—whether you're in Portland's aerospace sector or a SW Washington job shop—allows us to recommend the right calibration approach and schedule service with minimal production disruption.
Hear from Pacific Northwest manufacturers who rely on our precision calibration services to maintain production quality and eliminate unexpected downtime.
"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.
Precision in calibration refers to the measurement system's ability to consistently reproduce the same reading under identical conditions. Our services deliver accuracy to 1.0 parts per million (one millionth of an inch per inch), with measurements traceable to NIST and International Standards, well exceeding the 10:1 ratio required for proper calibration.
