Sarkinen Calibrating delivers NIST-traceable precision calibration for CNC machines, rotary axes, and measurement equipment across manufacturing facilities. Founded by a former machine operator, we understand production realities—our laser interferometry and diagnostic services verify accuracy to one millionth of an inch, eliminate unexpected downtime, and ensure your equipment meets specifications every time. From new machine warranty verification to ongoing performance monitoring, we keep your operations predictable and your parts precise.
Comprehensive calibration solutions for CNC machines, rotary systems, and precision measurement equipment with NIST-traceable accuracy.
Verify positioning accuracy, repeatability, straightness, and squareness across full axis travel using Renishaw's system. Achieve 1.0 part per million accuracy—ideal for warranty validation and identifying shipping damage before production begins.
Quickly evaluate CNC machine health with Renishaw's QC20-W Ballbar. Identify backlash, servo mismatch, and squareness issues to validate service work and support maintenance planning with minimal downtime.
Measure angular positioning accuracy and alignment of rotary tables using Renishaw's system. Detect mechanical wear, setup errors, and encoder issues affecting multi-axis machining precision.
Detect pitch and roll errors in machine beds and guideways using Mahr-Federal's system. Identify alignment issues from installation or foundation movement affecting large machine accuracy.
Maintain reference plane accuracy through expert leveling and flatness measurement using Moody Plot analysis. Monitor wear over time to ensure consistent inspection results.
Hands-on instruction for CAM software, CNC operation, laser interferometry, and ballbar systems. Empower your team to perform diagnostics and understand machine accuracy data.
Initial Equipment Assessment
We evaluate your machine's current condition, operational history, and specific accuracy requirements. For Portland-area manufacturers, we schedule assessments to minimize production disruption and identify priority measurement areas based on your part tolerances and recent machining issues.

Founder
Larry's journey from machine operator to calibration specialist gives Sarkinen Calibrating a unique perspective on manufacturing accuracy. Having experienced firsthand the frustrations of unexpected downtime and quality issues, he built a calibration service focused on practical solutions rather than just equipment maintenance. Larry understands that calibration isn't about hitting technical specifications—it's about keeping production running smoothly and delivering parts that meet customer expectations every time. His operator background allows him to quickly diagnose the real-world impact of machine errors and recommend adjustments that improve both accuracy and efficiency. Under Larry's leadership, Sarkinen has become the go-to calibration provider for Portland OR and SW Washington manufacturers who need NIST-traceable accuracy delivered with minimal disruption to their operations.
Who is qualified to perform calibration?
Qualified calibration technicians must have specialized training in metrology, precision measurement systems, and the specific equipment being calibrated. At Sarkinen Calibrating, our team is trained on Renishaw laser interferometry, ballbar systems, and electronic leveling equipment, with all measurements traceable to NIST and International Standards. Our founder's background as a machine operator provides additional practical expertise in understanding how calibration affects real-world production.
