Maintain production accuracy and eliminate unexpected downtime with NIST-traceable calibration services designed for manufacturing environments. From laser interferometry to ballbar testing, our precision measurement solutions verify equipment performance to 1.0 parts per million, ensuring consistent part quality and reducing costly rework. Founded by a former machine operator who understands production floor challenges, we deliver comprehensive calibration that keeps your operations running predictably.
Comprehensive precision measurement solutions to verify equipment accuracy, identify wear patterns, and maintain production consistency across your facility.
Verify precision to 1.0 parts per million using laser interferometry. Measure positioning accuracy, repeatability, straightness, and squareness across full axis travel. Ideal for validating new machine specifications and identifying hidden damage before production impact.
Quick machine health assessment using wireless Renishaw QC20-W Ballbar. Evaluate circularity and identify backlash, servo mismatch, axis reversal errors, and squareness issues. Perfect for validating service work and troubleshooting accuracy problems.
Maintain reference plane accuracy through expert leveling and flatness verification with Moody Plot measurement. Monitor surface wear over time to preserve measurement reliability and ensure consistent inspection results throughout production operations.
Measure angular positioning accuracy, repeatability, and alignment using Renishaw's Rotary Calibration System. Identify mechanical wear, setup errors, or encoder issues affecting multi-axis machining on modern machine tools with rotary tables and trunnions.
Detect and correct pitch and roll errors on machine beds, guideways, and large structures. Identify alignment issues from installation, relocation, or foundation movement that affect axis geometry and machining stability on long-travel equipment.
Hands-on instruction for CAM software, CNC operation, laser interferometry, and ballbar systems. Learn proper setup, data collection, result interpretation, and troubleshooting techniques to perform in-house diagnostics and maximize machine capability.
Production environments demand predictable equipment performance. Our calibration services go beyond routine maintenance to provide comprehensive accuracy verification that eliminates guesswork. With measurements traceable to NIST standards and accuracy to one millionth of an inch per inch, we help you verify new machine specifications while under warranty, identify hidden damage from shipping and installation, and monitor ongoing performance to prevent quality issues. Founded by a former machine operator, we understand production floor realities and deliver solutions that increase efficiency while minimizing disruption.
Manufacturing facilities across the region rely on our calibration expertise to maintain precision and minimize 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.
Calibration in quality control is the process of verifying and adjusting measurement equipment to ensure it provides accurate, reliable readings that meet specified standards. For production environments, this means testing CNC machines, inspection equipment, and measurement tools against NIST-traceable standards to confirm they can deliver the precision required for consistent part quality. Proper calibration identifies errors before they cause production problems and provides documented proof that equipment performs as promised.
