Sarkinen Calibrating delivers NIST-traceable precision level calibration that ensures your CNC machines, surface plates, and manufacturing equipment maintain absolute accuracy. Our electronic leveling services identify and correct pitch, roll, and alignment errors that impact production quality—keeping your Portland OR and SW Washington operations running with predictable accuracy and minimal downtime.
Comprehensive calibration solutions that verify machine accuracy, identify wear patterns, and maintain production consistency with NIST-traceable measurements.
Precise detection and correction of pitch and roll errors using Mahr-Federal Electronic Level technology. Ideal for evaluating machine beds, guideways, and large structures where angular deviations affect accuracy and production consistency.
Expert leveling and flatness verification including Moody Plot analysis to maintain surface plate consistency. Ensures your reference planes remain accurate for inspection and layout work as plates naturally wear over time.
Renishaw Laser Interferometer testing with accuracy to 1.0 parts per million. Measures positioning accuracy, repeatability, straightness, and squareness across full axis travel with NIST-traceable results.
Renishaw Rotary Calibration System verification of angular positioning accuracy, repeatability, and alignment. Identifies mechanical wear, setup errors, and encoder issues affecting multi-axis machining performance.
Renishaw QC20-W Ballbar evaluation of circularity and machine health. Quick wireless testing identifies backlash, servo mismatch, axis reversal errors, and squareness problems to validate service work and plan maintenance.
Hands-on training for Laser Interferometer, Ballbar systems, and CNC operation. Learn proper setup, data interpretation, and troubleshooting techniques to perform in-house diagnostics and understand machine accuracy.
Manufacturing operations in Portland OR and SW Washington depend on equipment that performs predictably. Sarkinen Calibrating provides precision level calibration services that go beyond routine maintenance—we identify hidden alignment issues, verify new machine specifications while under warranty, and deliver measurements traceable to NIST and International Standards. Our local team responds faster than out-of-area providers, minimizing disruption while ensuring your CNC machines, surface plates, and production equipment maintain the accuracy your customers expect.
Serving precision manufacturers across Portland OR and SW Washington with calibration services that maintain production quality.
"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"
"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..."
"This guy knows his stuff. Would definately recommend! Friendly good people!"

Founder
Larry built Sarkinen Calibrating from his experience as a machine operator, bringing a unique perspective that goes far beyond equipment maintenance. He understands that calibration isn't just about numbers on a report—it's about keeping production lines running smoothly, maintaining part quality, and eliminating the unexpected downtime that disrupts manufacturing schedules. Throughout Portland OR and SW Washington, Larry has built lasting relationships with manufacturers who appreciate his practical approach to calibration challenges. His foundation as a machine operator means he looks at each calibration project through the lens of production efficiency, identifying solutions that improve both accuracy and operational workflow. This hands-on background allows Sarkinen Calibrating to deliver calibration services that truly support manufacturing operations rather than simply checking boxes on a compliance form.
What is precision level calibration and why is it important?
Precision level calibration measures and corrects angular deviations in machine beds, guideways, and equipment structures. Even minor pitch or roll errors can significantly impact machining accuracy, part quality, and measurement reliability. Regular calibration ensures your equipment maintains the geometric accuracy necessary for consistent production results.
