Sarkinen Calibrating delivers NIST-traceable machine tool laser calibration and alignment services with accuracy to 1.0 parts per million. From laser interferometry to ballbar testing, we verify your CNC equipment meets specifications and maintains peak performance. Our founder's experience as a machine operator means we understand your production demands and deliver solutions that minimize downtime while maximizing quality.
Complete laser calibration and alignment solutions for CNC machines, rotary axes, and precision equipment with NIST-traceable accuracy.
Verify positioning accuracy, repeatability, straightness, and squareness across full axis travel using Renishaw Laser Interferometry. Achieve 1.0 ppm accuracy with NIST-traceable measurements that exceed 10:1 calibration ratios and identify hidden damage or installation errors.
Evaluate CNC machine health quickly using Renishaw QC20-W Ballbar to measure circularity and identify backlash, servo mismatch, axis reversal errors, and squareness problems. Wireless setup minimizes downtime while validating service work and supporting maintenance planning.
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 before they impact part quality.
Detect and correct 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 that affect axis geometry and machining stability.
Maintain surface plate consistency through expert leveling and flatness verification with Moody Plot analysis. Ensure your reference planes remain accurate for inspection and layout work as wear naturally occurs over time in production environments.
Learn hands-on operation of Renishaw Laser Interferometer, QC20-W Ballbar, CAM software, and CNC milling machines. Gain practical skills in setup, data collection, result interpretation, and troubleshooting to perform in-house diagnostics and improve machine capability.
Initial Consultation & Machine Assessment
We begin by understanding your production requirements, machine history, and accuracy concerns. Our team evaluates your equipment type, age, and operating conditions to recommend the most appropriate calibration services. With faster local response times than out-of-area providers, we schedule service that minimizes production disruption.

Founder
Larry's journey into precision calibration began on the shop floor as a machine operator, giving him firsthand understanding of how equipment accuracy directly impacts production quality and efficiency. This unique perspective shaped his approach when he founded Sarkinen Calibrating—building a service that goes beyond routine maintenance to deliver real solutions for manufacturing operations. Larry recognized that calibration isn't just about meeting specifications on paper; it's about helping machine shops and production facilities eliminate unexpected downtime, verify new equipment meets promised performance while still under warranty, and maintain the predictable operation that keeps production schedules on track. His operator experience means he understands the frustration of accuracy problems that slow production and the value of having local support that responds quickly when issues arise. Today, Larry leads a team that serves Portland OR and SW Washington with NIST-traceable measurements, comprehensive diagnostics using Renishaw and Mahr-Federal equipment, and the kind of practical advice that only comes from years of working with machines in real production environments.
