Precision machine performance shouldn't be a guessing game. Our Renishaw QC20-W Ballbar testing delivers fast, reliable diagnostics that identify critical wear issues, verify service work, and keep your CNC machines running at peak accuracy. With NIST-traceable measurements and same-day reporting, we help manufacturing facilities across Portland and SW Washington eliminate unexpected downtime before it impacts production quality.
Comprehensive machine accuracy evaluation services using Renishaw's industry-leading diagnostic tools to keep your production equipment performing at specification.
Fast circularity testing using Renishaw's QC20-W Ballbar identifies backlash, servo mismatch, axis reversal errors, and squareness problems. Wireless setup minimizes downtime while delivering repeatable results that validate service work and support maintenance planning.
Precision verification using Renishaw's Laser Interferometer with accuracy to 1.0 part per million. Measures positioning accuracy, repeatability, straightness, and squareness across full axis travel to identify alignment errors and hidden damage.
Accurate rotary axis evaluation using Renishaw's Rotary Calibration System verifies angular positioning, repeatability, and alignment of rotary tables and trunnions. Identifies mechanical wear, setup errors, and encoder issues affecting multi-axis machining.
Precise pitch and roll error detection using Mahr-Federal's Electronic Level evaluates machine beds, guideways, and large structures. Identifies alignment issues from installation, relocation, or foundation movement that affect axis geometry.
Expert leveling and flatness verification including Moody Plot analysis ensures surface plates maintain accurate reference planes. Monitors wear patterns that affect part accuracy and measurement reliability in production inspection environments.
Hands-on training for Renishaw Laser Interferometer and QC20-W Ballbar systems covers setup, data collection, result interpretation, and troubleshooting. Ideal for maintenance teams and quality engineers performing in-house diagnostics.
Pre-Test Consultation & Scheduling
We discuss your specific accuracy concerns, recent service history, and production requirements. As a local Portland-area provider, we schedule testing to minimize disruption to your manufacturing operations and can typically respond faster than out-of-area calibration services.

Founder
Larry founded Sarkinen Calibrating with a unique perspective that sets the company apart in the precision calibration industry. Starting his career as a machine operator, Larry experienced firsthand the production challenges that come from equipment inaccuracy and unexpected downtime. This operator-level understanding shaped his approach to calibration services—it's never been just about equipment maintenance for Larry. Instead, he built Sarkinen Calibrating around a philosophy of looking at complete machining operations and providing solutions that genuinely increase production quality and efficiency. Larry's background gives him insight into what manufacturing facilities truly need: predictable accuracy, minimal disruption, and calibration services that support real production goals rather than just checking compliance boxes. His commitment to customer service and operational excellence continues to guide every diagnostic service Sarkinen Calibrating provides across Portland OR and SW Washington.
