Precision manufacturing demands precision calibration. Sarkinen Calibrating delivers NIST-traceable measurement services that verify equipment accuracy, eliminate unexpected downtime, and ensure your CNC machines, surface plates, and rotary axes perform exactly as specified. Our comprehensive calibration solutions go beyond maintenance—we identify hidden errors before they impact production quality, helping Portland-area manufacturers maintain consistent output and meet the tightest tolerances with confidence.
Comprehensive precision measurement and machine performance verification solutions that ensure accuracy, eliminate downtime, and maintain production quality across your manufacturing operations.
Verify CNC machine positioning accuracy to 1.0 part per million using Renishaw's Laser Interferometer. NIST-traceable measurements evaluate positioning accuracy, repeatability, straightness, and squareness across full axis travel—ideal for warranty verification and ongoing quality assurance.
Quick machine health diagnostics using Renishaw's QC20-W Ballbar to identify backlash, servo mismatch, axis reversal errors, and squareness problems. Wireless testing minimizes downtime while providing reliable circularity evaluation and performance validation.
Maintain inspection accuracy through expert leveling and flatness verification with Moody Plot analysis. Continuous monitoring prevents wear-related measurement drift that compromises part accuracy and quality control confidence.
Measure angular positioning accuracy, repeatability, and alignment using Renishaw's Rotary Calibration System. Identify mechanical wear, setup errors, or encoder issues affecting multi-axis machining performance before they impact production.
Detect and correct pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal's Electronic Level. Precise angular measurement identifies alignment issues from installation, relocation, or foundation movement.
Hands-on instruction for Renishaw measurement systems, CAM software, and CNC operation. Practical training covers proper setup, data interpretation, and troubleshooting techniques tailored to your equipment and team skill level.
Founded by a machine operator who understands production floors firsthand, Sarkinen Calibrating approaches calibration as more than equipment maintenance—it's about protecting your production quality and operational efficiency. Our NIST-traceable measurements exceed industry-required 10:1 accuracy ratios, providing definitive proof that your machines deliver as promised. Whether verifying new equipment under warranty or diagnosing unexpected quality issues, we identify hidden errors before they become costly problems. With faster local response times than out-of-area providers, we keep Portland and SW Washington manufacturers running predictably with minimal disruption.

Founder
Larry's journey from machine operator to calibration service founder gives Sarkinen Calibrating a unique perspective in the precision measurement industry. Unlike providers who view calibration as purely technical maintenance, Larry understands the real-world pressures of production environments—the consequences of unexpected downtime, the importance of consistent quality output, and the need for equipment that performs exactly as promised. This operator-first philosophy shaped the company's approach: delivering solutions that don't just verify accuracy but actively increase production quality and efficiency. Larry built Sarkinen Calibrating on the principle that effective calibration service requires understanding machining operations holistically, identifying potential issues before they disrupt production, and providing manufacturers with the confidence that their equipment will deliver reliable results every time. His hands-on background continues to inform every aspect of how the company serves Portland OR and SW Washington manufacturers.
What does manufacturing calibration service include?
Manufacturing calibration services verify that your precision equipment performs within specified tolerances. This includes laser interferometer measurements for linear axis accuracy, ballbar testing for machine circularity and performance, surface plate flatness verification, rotary axis calibration, and electronic leveling for machine structures. All measurements are NIST-traceable and documented with detailed reports.
