Master the precision skills that manufacturing employers demand. Sarkinen Calibrating offers hands-on CNC maintenance technician training that combines real-world calibration expertise with NIST-traceable measurement techniques. Whether you're starting your career or advancing your technical capabilities, our comprehensive certification programs teach you to diagnose machine issues, perform accurate measurements, and maintain equipment that meets industry standards—skills that translate directly to higher earning potential and job security in today's precision manufacturing environment.
Comprehensive hands-on training programs designed to build real-world skills in CNC calibration, measurement, and machine maintenance.
Master Renishaw's Laser Interferometer for NIST-traceable linear calibration. Learn proper setup, data collection, and interpretation of positioning accuracy, repeatability, straightness, and squareness measurements to verify machine performance with precision to one millionth of an inch.
Learn to use Renishaw's QC20-W Ballbar system to quickly assess CNC machine health. Identify backlash, servo mismatch, axis reversal errors, and squareness issues through circularity testing—one of the most effective diagnostic tools in modern machine maintenance.
Gain practical skills in CNC milling machine operation and CAM software programming. Understand how machine geometry and calibration directly affect part quality, while learning setup procedures, operation best practices, and error reduction techniques for real production environments.
Develop expertise in surface plate leveling, flatness verification, and Moody Plot interpretation. Learn to maintain the accuracy of inspection reference planes and understand how surface wear impacts measurement reliability in production settings.
Master rotary axis accuracy verification using Renishaw's Rotary Calibration System. Learn to measure angular positioning, repeatability, and alignment of rotary tables and trunnions, identifying mechanical wear and setup errors that affect multi-axis machining precision.
Train with Mahr-Federal's Electronic Level to detect and correct pitch and roll errors in machine beds, guideways, and large structures. Learn to identify alignment issues from installation, relocation, or foundation movement that compromise machining accuracy.
Founded by Larry, a former machine operator who built a calibration service from the ground up, Sarkinen Calibrating delivers training that goes beyond theory. Our programs focus on practical application, real troubleshooting scenarios, and the kind of problem-solving skills that reduce downtime in actual production environments. You'll learn NIST-traceable measurement techniques, interpret calibration data like a professional, and understand how machine accuracy directly impacts part quality—knowledge that makes you invaluable to employers across the Portland and SW Washington manufacturing sector.
Join technicians who've advanced their careers through our certification programs trusted by leading manufacturers.
"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 & Lead Instructor
Larry's journey in precision manufacturing started on the shop floor as a machine operator, where he developed a deep understanding of the challenges that affect production quality and efficiency. That hands-on experience became the foundation for Sarkinen Calibrating, a service built not just to maintain equipment, but to solve real operational problems that impact manufacturing success. Over the years, Larry expanded his expertise to include advanced calibration techniques, NIST-traceable measurement systems, and comprehensive machine diagnostics. His approach to training reflects his operator background—practical, results-oriented, and focused on skills that immediately improve job performance. Larry understands what it takes to succeed in precision manufacturing because he's been there himself, and he's committed to helping the next generation of technicians build careers on a foundation of accuracy, reliability, and professional excellence.
