Eliminate unexpected downtime and maximize production quality with NIST-traceable calibration services accurate to 1.0 parts per million. Founded by a former machine operator, Sarkinen Calibrating delivers comprehensive precision engineering solutions that go beyond equipment maintenance—ensuring your CNC machines, surface plates, and rotary systems perform exactly as promised, every time.
Complete calibration solutions for CNC machines, measurement equipment, and precision manufacturing systems—traceable to NIST standards.
Verify positioning accuracy, repeatability, straightness, and squareness using laser interferometry accurate to 1.0 parts per million. Identify shipping damage, installation errors, and hidden alignment issues before they impact production quality.
Fast wireless evaluation of CNC machine health using Renishaw's QC20-W Ballbar. Identifies backlash, servo mismatch, axis reversal errors, and squareness problems to validate service work and support maintenance planning.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions. Detect mechanical wear, setup errors, and encoder issues that compromise multi-axis machining accuracy.
Expert leveling and flatness verification including Moody Plot measurements. Maintain consistency and confidence in inspection results as surface plates wear over time and affect part accuracy.
Detect and correct pitch and roll errors in machine beds, guideways, and large structures. Identify alignment issues from installation, relocation, or foundation movement affecting axis geometry.
Hands-on instruction for laser interferometer, ballbar systems, CAM software, and CNC operation. Tailored training helps operators, programmers, and technicians maximize machine capability and reduce errors.
Initial Assessment & Equipment Setup
Our technician arrives on-site with calibrated Renishaw measurement systems and evaluates your machine's current condition. We review your production requirements, recent service history, and any accuracy concerns affecting Portland-area manufacturers. Setup is performed with minimal disruption to your operations.

Founder
Larry founded Sarkinen Calibrating after years of hands-on experience as a machine operator, giving him a unique perspective that goes far beyond typical calibration services. He recognized early on that precision calibration isn't just about equipment maintenance—it's about understanding the entire machining operation and delivering solutions that genuinely increase production quality and efficiency. This operator-first mindset shaped the company's approach from day one. Larry built the business to serve Portland OR and SW Washington manufacturers who need more than just measurements—they need a partner who understands production realities, downtime costs, and the importance of keeping equipment accurate between service intervals. His philosophy is simple: provide the best customer service possible by treating calibration as a critical production tool, not just a compliance checkbox. Today, Sarkinen Calibrating continues that mission with NIST-traceable accuracy, faster local response times, and comprehensive solutions that eliminate unexpected downtime.
What is precision in calibration?
Precision in calibration refers to how closely repeated measurements agree with each other and how accurately measurement equipment performs against known reference standards. At Sarkinen Calibrating, we achieve precision to 1.0 parts per million (one millionth of an inch per inch) using laser interferometry, with all measurements traceable to NIST and international standards. This level of precision ensures your machines perform exactly as specified and produce consistent, accurate parts.
