Precision CNC calibration that eliminates unexpected downtime and ensures your machines deliver consistent accuracy. Sarkinen Calibrating provides NIST-traceable testing to verify positioning, identify hidden wear, and maintain production quality. Founded by a former machine operator who understands what precision manufacturing demands, we deliver faster response times and comprehensive diagnostics that keep your operation running predictably.
Comprehensive precision calibration solutions ensuring your CNC equipment maintains NIST-traceable accuracy and minimizes unexpected downtime.
Verify positioning accuracy to 1.0 parts per million using Renishaw Laser Interferometer. Measure positioning accuracy, repeatability, straightness, and squareness across full axis travel. Identify alignment errors from shipping, installation, or wear before warranty expiration.
Fast CNC health assessment using Renishaw QC20-W Ballbar. Evaluate circularity and identify backlash, servo mismatch, axis reversal errors, and squareness problems. Validate service work and support maintenance planning with wireless setup that minimizes downtime.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's Rotary Calibration System. Identify mechanical wear, setup errors, or encoder issues affecting multi-axis machining accuracy.
Detect pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal Electronic Level. Identify alignment issues from installation, relocation, or foundation movement affecting axis geometry and machining stability.
Maintain reference plane accuracy through expert leveling and flatness verification including Moody Plot measurement. Monitor wear over time to ensure consistent inspection and layout work reliability in production environments.
Hands-on training for laser interferometer, ballbar systems, CAM software, and CNC operation. Learn proper setup, data interpretation, and troubleshooting techniques tailored to your equipment and skill level for in-house diagnostics.
Manufacturing precision demands more than routine maintenance—it requires calibration expertise rooted in production reality. Our founder started as a machine operator, so we understand that every micron matters when quality and delivery schedules are on the line. We deliver measurements traceable to NIST and International Standards, exceeding the required 10:1 ratio. From identifying hidden shipping damage before warranty expiration to diagnosing mysterious accuracy drift, our comprehensive diagnostics give you proof your machines can deliver as promised, every time.
Leading manufacturers trust Sarkinen Calibrating to keep their CNC operations accurate and predictable.
"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 founded Sarkinen Calibrating after years of hands-on experience as a machine operator, giving him a unique perspective that goes far beyond typical equipment maintenance. He understands firsthand the frustration of unexpected machine errors, the pressure of tight production schedules, and the critical importance of maintaining consistent accuracy. This operational background shapes every calibration service Sarkinen provides—it's not just about testing equipment, it's about delivering solutions that increase production quality and efficiency. Larry built the company on the principle that precision calibration should minimize downtime, eliminate surprises, and give manufacturers confidence their machines will perform as promised every single time. His commitment to customer service and comprehensive diagnostics has made Sarkinen Calibrating the trusted local provider for Portland OR and SW Washington manufacturing operations that demand NIST-traceable accuracy with minimal disruption.
What is CNC machine error testing and why is it important?
CNC machine error testing uses precision measurement systems to verify positioning accuracy, repeatability, straightness, and squareness of machine axes. It's critical because even minor errors from shipping, installation, wear, or misalignment can significantly impact part quality and cause unexpected production downtime. Regular testing identifies issues before they affect your bottom line.
