Sarkinen Calibrating delivers NIST-traceable machine accuracy calibration services with precision to 1.0 parts per million. Serving Portland OR and SW Washington manufacturers, we identify alignment errors, mechanical wear, and hidden damage before they impact production. Our founder's machine operator background ensures we provide solutions that minimize downtime and maximize production quality.
Complete precision measurement and calibration solutions for CNC machines, rotary axes, and inspection equipment throughout the Pacific Northwest.
Verify positioning accuracy, repeatability, straightness, and squareness using Renishaw's Laser Interferometer with NIST-traceable precision to 1.0 parts per million. Ideal for warranty verification and identifying shipping or installation damage.
Fast machine health assessment using Renishaw's QC20-W Ballbar to identify backlash, servo mismatch, axis reversal, and squareness issues. Validates service work and supports maintenance planning with minimal downtime.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's Rotary Calibration System. Identifies mechanical wear, setup errors, and encoder issues affecting multi-axis machining.
Expert leveling and flatness verification including Moody Plot analysis to maintain accurate reference planes for inspection and layout work. Monitors wear patterns that affect measurement reliability over time.
Detect pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal's Electronic Level. Critical for identifying alignment issues from installation, relocation, or foundation movement.
Hands-on instruction for CAM software, CNC operation, and calibration equipment including Renishaw's Laser Interferometer and Ballbar systems. Tailored to your equipment and skill level for improved efficiency.
Pacific Northwest manufacturers trust Sarkinen Calibrating because we understand machine accuracy from an operator's perspective. Our measurements exceed industry standards by 10:1, identifying hidden issues before they become production problems. With faster response times than out-of-area providers and comprehensive diagnostics that go beyond basic equipment maintenance, we keep Portland OR and SW Washington facilities running predictably. Every measurement is fully traceable to NIST and International Standards, giving you proof that your machines deliver as promised.
Manufacturing facilities across Portland and SW Washington rely on our precision calibration expertise.
"I have worked with Mr Sarkinen on a job in Portland He is a Highly Skilled, Knowledgable Professional. I would definitely recomend him for all your Machine Tool Calibration Metrics. Sincerely Curtis Page Naughtellis CNC Service"
"As plant manager at Triad, I am always looking for ways of testing and measuring the condition of our large machines. Our outside repair tech suggested that I have Sarkinen Calibrating run their Ball Bar Test on all of our machines to show if we had any critical wear issues..."
"This guy knows his stuff. Would definately recommend! Friendly good people!"

Founder
Larry's journey into precision calibration began on the shop floor as a machine operator, giving him firsthand understanding of how equipment accuracy directly impacts production quality and efficiency. This practical foundation shaped his vision for Sarkinen Calibrating—a service that goes beyond routine equipment maintenance to deliver comprehensive solutions for manufacturing operations. Drawing on years of machining experience, Larry built a calibration business focused on eliminating unexpected downtime and helping facilities maintain consistent, predictable performance. His operator's perspective ensures every calibration service addresses real production challenges, whether verifying new machine specifications under warranty or identifying wear patterns before they affect part quality. Today, Sarkinen Calibrating serves Portland OR and SW Washington with NIST-traceable measurements and faster response times than out-of-area providers, all rooted in Larry's commitment to practical solutions that increase production quality and operational efficiency.
