Maintain precision and eliminate costly downtime with NIST-traceable laser calibration services for CNC machines and manufacturing equipment. Sarkinen Calibrating uses Renishaw's advanced laser interferometry to verify positioning accuracy to 1.0 part per million, ensuring your machine tools deliver consistent quality and meet specification standards throughout their service life.
Comprehensive machine tool calibration solutions using advanced laser interferometry and precision measurement technology for optimal equipment performance.
Verify positioning accuracy, repeatability, straightness, and squareness across full axis travel using Renishaw laser interferometry with 1.0 PPM accuracy. NIST-traceable measurements exceed the 10:1 calibration ratio, identifying alignment errors and hidden damage before warranty expiration.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's Rotary Calibration System. Identifies mechanical wear, setup errors, and encoder issues affecting multi-axis machining precision.
Evaluate machine circularity and overall health using Renishaw's QC20-W Ballbar. Quickly identifies backlash, servo mismatch, axis reversal errors, and squareness problems. Wireless setup minimizes downtime while validating service work and supporting maintenance planning.
Detect pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal Electronic Level. Identifies alignment issues from installation, relocation, or foundation movement affecting axis geometry and machining stability.
Maintain reference plane accuracy through expert leveling and flatness verification with Moody Plot measurement. Monitors surface wear over time to ensure continued measurement reliability and consistent inspection results in production environments.
Hands-on instruction for Renishaw laser interferometer and ballbar systems. Learn proper setup, data collection, result interpretation, and troubleshooting. Ideal for maintenance teams and quality engineers performing in-house diagnostics.
Manufacturing facilities depend on machine tool accuracy to maintain tight tolerances and consistent part quality. Sarkinen Calibrating delivers laser calibration services with measurements traceable to NIST and International Standards, achieving accuracy to 1.0 part per million—well beyond the 10:1 ratio required for proper calibration. Founded by a former machine operator who understands production pressures, we identify alignment errors, verify new equipment specifications while under warranty, and eliminate unexpected downtime that impacts delivery schedules and customer confidence.
Manufacturing facilities across Portland and SW Washington rely on our calibration expertise for predictable machine performance.
"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's career path from machine operator to calibration service founder gives Sarkinen Calibrating a unique perspective on manufacturing precision. He didn't start in metrology labs or equipment sales—he started on the shop floor, running machines and experiencing firsthand how calibration issues impact production schedules, part quality, and customer relationships. That operator-level understanding shapes every service call. Larry built Sarkinen Calibrating on the principle that calibration isn't just equipment maintenance—it's about looking at complete machining operations and providing solutions that increase production quality and efficiency. His approach focuses on preventing the unexpected downtime and quality inconsistencies that disrupt manufacturing operations. Today, Sarkinen Calibrating serves Portland OR and SW Washington with NIST-traceable measurement capabilities, helping manufacturing facilities maintain the precision accuracy their customers depend on.
What is laser calibration for machine tools?
Laser calibration uses precision laser interferometry to measure positioning accuracy, repeatability, straightness, and squareness of machine tool axes. It verifies that machine movements match programmed commands and identifies errors affecting part quality. Sarkinen Calibrating uses Renishaw laser systems with NIST-traceable accuracy to 1.0 part per million.
