Keep your manufacturing operations running at peak performance with comprehensive machine condition monitoring. Sarkinen Calibrating delivers NIST-traceable precision measurements that identify wear, misalignment, and accuracy drift before they impact production quality. Our local expertise minimizes downtime while ensuring your equipment maintains the tight tolerances modern manufacturing demands.
Comprehensive measurement and diagnostic solutions that verify accuracy, identify wear patterns, and prevent unexpected downtime across your precision equipment.
Verify positioning accuracy to 1.0 PPM using Renishaw Laser Interferometry. Measure accuracy, repeatability, straightness, and squareness across full axis travel with NIST-traceable results that identify alignment issues before warranty expiration.
Rapid CNC health assessment using Renishaw QC20-W Ballbar. Evaluate circularity, detect backlash, servo mismatch, axis reversal errors, and squareness problems. Ideal for validating service work and troubleshooting accuracy issues.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's Rotary Calibration System. Identify encoder issues, mechanical wear, and setup errors affecting multi-axis machining precision.
Detect pitch and roll errors using Mahr-Federal Electronic Level. Evaluate machine beds, guideways, and structures to identify alignment issues from installation, relocation, or foundation movement affecting axis geometry.
Maintain reference plane accuracy through expert leveling and flatness verification including Moody Plot analysis. Ensure consistent measurement reliability as wear occurs, preventing accuracy drift in inspection and layout operations.
Hands-on instruction for Renishaw Laser Interferometer and QC20-W Ballbar systems. Learn setup, data collection, result interpretation, and troubleshooting to perform in-house diagnostics and understand machine accuracy data.
Machine accuracy doesn't stay constant—it degrades gradually through normal wear, thermal cycling, and vibration. Without regular condition monitoring, this degradation remains invisible until parts fail inspection or tolerances are suddenly out of spec. Sarkinen Calibrating provides objective, measurable data that reveals exactly how your equipment is performing. Our measurements exceed the 10:1 ratio required for proper calibration and are fully traceable to NIST standards, giving you confidence that accuracy issues are caught early. Whether you're validating new equipment under warranty, troubleshooting quality problems, or planning preventive maintenance, our condition monitoring delivers the evidence you need to make informed decisions.
Manufacturing leaders rely on our precision monitoring to maintain quality and prevent 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!"

Experience built from the shop floor up.
Founder
Larry's journey into precision calibration began not in a lab, but on the production floor as a machine operator. That hands-on experience taught him something most calibration providers miss—equipment maintenance isn't just about meeting specifications on paper. It's about understanding how machines actually perform under production pressure, how small accuracy drifts compound into quality problems, and how unexpected downtime disrupts entire operations. When Larry founded Sarkinen Calibrating, he brought that operator's perspective to every measurement. He saw calibration as a production solution, not just a compliance exercise. Today, that philosophy drives everything the company does—providing NIST-traceable accuracy with the responsiveness and practical insight that comes from truly understanding manufacturing operations. For Larry, every calibration job is about helping customers achieve what he valued as an operator: predictable performance, consistent quality, and the confidence that equipment will deliver exactly what's needed, when it's needed.
How often should I have my CNC machines condition monitored?
Frequency depends on production volume, material hardness, and tolerance requirements. Most facilities benefit from annual monitoring as a baseline, with more frequent checks (quarterly or semi-annually) for high-volume production or tight-tolerance work. New equipment should be verified before warranty expiration, and any machine showing quality inconsistencies should be evaluated immediately.
