Sarkinen Calibrating delivers NIST-traceable precision calibration services across Washington and Oregon, ensuring your CNC machines and manufacturing equipment maintain the accuracy Portland-area production demands. From laser interferometry to ballbar testing, we eliminate unexpected downtime and verify that every axis, surface plate, and rotary component performs exactly as specified—keeping your operations predictable and your parts within tolerance.
Comprehensive machine accuracy solutions from laser interferometry to electronic leveling, all NIST-traceable and designed to minimize production disruptions.
Verify CNC linear axis positioning accuracy, repeatability, straightness, and squareness using Renishaw Laser Interferometer. Measurements to 1.0 PPM ensure new machines meet warranty specs and identify hidden damage before production impact.
Rapidly evaluate CNC machine health with Renishaw QC20-W Ballbar. Identifies backlash, servo mismatch, axis reversal errors, and squareness issues. Validates service work and supports maintenance planning with minimal setup time.
Maintain reference plane accuracy through expert leveling and flatness verification using Moody Plot analysis. Monitors wear patterns to preserve inspection reliability and measurement consistency across production environments.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions. Identifies mechanical wear, encoder issues, and setup errors affecting multi-axis machining precision on modern machine tools.
Detect and correct pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal Electronic Level. Ideal for identifying alignment issues from installation, relocation, or foundation movement.
Hands-on training for CAM software, CNC operation, laser interferometer, and ballbar systems. Tailored sessions help operators, programmers, and technicians maximize machine capability and interpret calibration data effectively.
Pre-Service Consultation & Equipment Assessment
We begin with a detailed discussion of your machining operations, production requirements, and any accuracy concerns. Understanding your facility's needs—whether you're in Portland's aerospace sector or a SW Washington job shop—allows us to recommend the right calibration approach and schedule service with minimal production disruption.

Calibration expertise built on real production experience.
Founder
Larry founded Sarkinen Calibrating after years of hands-on experience as a machine operator, giving him a unique perspective that goes far beyond technical specifications. He understands that calibration isn't just about maintaining equipment—it's about solving real production challenges, reducing scrap, and keeping operations running smoothly. That operator's viewpoint shaped the company's entire approach: focusing on practical solutions that increase production quality and efficiency rather than simply checking boxes on a service report. Larry built the business to serve manufacturers throughout Portland, SW Washington, and the surrounding region with the kind of responsive, knowledgeable service that comes from someone who has stood at the machine and dealt with the same accuracy issues his customers face every day. His commitment to minimizing downtime and maximizing machine capability drives every calibration service Sarkinen provides.
What is precision in calibration?
Precision in calibration refers to the measurement system's ability to consistently reproduce the same reading under identical conditions. Our services deliver accuracy to 1.0 parts per million (one millionth of an inch per inch), with measurements traceable to NIST and International Standards, well exceeding the 10:1 ratio required for proper calibration.
