Transform your manufacturing capabilities with precision CNC machining calibration that ensures every custom part meets exact specifications. Sarkinen Calibrating delivers NIST-traceable accuracy to 1.0 parts per million, helping Portland OR and SW Washington manufacturers eliminate unexpected downtime and maintain production quality. Our founder's machine operator background means we understand your challenges and provide solutions that increase efficiency, not just equipment maintenance.
Comprehensive calibration solutions ensuring your CNC machines deliver consistent accuracy and quality for every custom part.
Verify positioning accuracy to 1.0 parts per million using Renishaw's Laser Interferometer. Measure accuracy, repeatability, straightness, and squareness across full axis travel with NIST-traceable results that identify issues before they impact production.
Quickly evaluate machine health with Renishaw's QC20-W Ballbar. Identify backlash, servo mismatch, axis reversal errors, and squareness problems to validate service work, troubleshoot accuracy issues, and plan future maintenance.
Ensure accurate angular positioning, 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 precision.
Maintain reference plane accuracy through expert leveling and flatness verification with Moody Plot analysis. Monitor surface plate wear to ensure consistent inspection results and measurement reliability in production environments.
Detect pitch and roll errors on machine beds, guideways, and large structures using Mahr-Federal's Electronic Level. Identify alignment issues from installation, relocation, or foundation movement to support stable machining performance.
Hands-on training for CAM software, CNC operation, laser interferometry, and ballbar systems. Tailored instruction helps operators, programmers, and technicians improve efficiency, reduce errors, and maximize machine capability.
Initial Assessment and Planning
We begin with a thorough evaluation of your CNC equipment, production requirements, and quality goals. Our team reviews machine history, identifies critical measurement points, and develops a customized calibration plan that minimizes disruption to your Portland or SW Washington production schedule while addressing your specific accuracy needs.

Founder
Larry's journey into precision calibration began on the machine shop floor, where he gained firsthand understanding of the challenges manufacturers face in maintaining accuracy and minimizing downtime. His experience as a CNC machine operator gave him unique insight into how calibration directly impacts production quality, efficiency, and profitability. This perspective shaped his vision for Sarkinen Calibrating—a service that goes beyond routine equipment maintenance to provide comprehensive solutions for machining operations. Larry built the company around the principle that calibration should deliver predictable, reliable performance with minimal disruption to production. His operator background allows him to communicate effectively with shop floor teams, understand real-world production constraints, and identify accuracy issues that others might overlook. Today, Larry leads a calibration service trusted by Portland OR and SW Washington manufacturers who need NIST-traceable precision delivered by someone who truly understands their business.
What is the difference between CNC and precision machining?
CNC (Computer Numerical Control) refers to the automated control system that operates machining equipment, while precision machining describes the level of accuracy achieved in the manufacturing process. Precision CNC machining combines computer-controlled automation with tight tolerances and exact specifications to produce custom parts with consistent accuracy. Our calibration services ensure your CNC machines maintain the precision needed for high-quality custom parts.
