Expert CNC Calibration Services for Manufacturing Facilities

Eliminate unexpected downtime and maintain production quality with precision CNC calibration services built for accuracy. Our NIST-traceable measurements detect alignment errors, mechanical wear, and accuracy drift before they impact your parts. From laser interferometry to ballbar testing, we deliver comprehensive diagnostics that keep your machining operations predictable, efficient, and producing to specification every time.

Our CNC Calibration Services

Comprehensive precision measurement solutions to verify machine accuracy, identify wear patterns, and maintain production quality across your entire facility.

Laser Interferometry

Verify linear axis positioning with NIST-traceable accuracy to 1.0 parts per million. Measure positioning accuracy, repeatability, straightness, and squareness across full travel to detect shipping damage, installation errors, or specification deviations before production impact.

Ballbar Testing

Fast evaluation of machine health using wireless ballbar technology. Identify backlash, servo mismatch, axis reversal errors, and squareness problems. Validate service work, troubleshoot accuracy issues, and support maintenance planning with repeatable circularity diagnostics.

Rotary Axis Calibration

Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions. Verify proper installation and ongoing calibration to prevent multi-axis machining errors caused by mechanical wear, setup problems, or encoder drift.

Surface Plate Verification

Maintain reference plane accuracy through expert leveling and flatness verification with Moody Plot analysis. Ensure consistent inspection results as plates wear over time, preserving measurement reliability and part acceptance confidence for layout work.

Electronic Leveling

Detect pitch and roll errors in machine beds, guideways, and large structures using precision electronic levels. Identify alignment issues from installation, relocation, or foundation movement that affect axis geometry and machining stability.

Calibration Training

Hands-on instruction for laser interferometry, ballbar systems, CAM software, and CNC operation. Tailored to your equipment and skill level, empowering teams to perform in-house diagnostics, interpret accuracy data, and maximize machine capability.

NIST-Traceable Accuracy

Precision Calibration That Protects Your Production Investment

Manufacturing success depends on machines that deliver consistent, predictable accuracy. Our comprehensive calibration services go beyond routine maintenance to provide actionable insights into machine health. Using advanced laser interferometry and wireless ballbar technology, we measure positioning accuracy, detect hidden wear patterns, and verify alignment across every critical axis. Each measurement is traceable to NIST standards and exceeds the required 10:1 calibration ratio. Whether validating new equipment under warranty or maintaining production machines, our diagnostics identify problems before they affect part quality, helping Portland-area manufacturers minimize adjustments, eliminate unexpected failures, and maintain customer confidence.

Larry, Founder of Sarkinen Calibrating

Larry

Founder

Larry's journey from machine operator to calibration service founder gives him a unique perspective that goes far beyond equipment maintenance. Having operated CNC machines firsthand, he understands the real-world production challenges manufacturers face daily—the frustration of unexpected downtime, the cost of scrap from axis errors, and the pressure to maintain tight tolerances. This operator-level experience drives his approach to calibration: it's not just about verifying numbers, it's about delivering solutions that genuinely increase production quality and efficiency. Larry built Sarkinen Calibrating on the principle that precision calibration should eliminate problems before they disrupt operations, providing manufacturers with the confidence that their equipment will perform exactly as promised. His hands-on background means he approaches every calibration with practical insight into how machine accuracy directly impacts your production floor, helping you achieve highly predictable operation with minimal disruption.
