Linear Axis Calibration
Laser interferometer verification of positioning accuracy, repeatability, straightness, and squareness across full axis travel with NIST-traceable measurements to 1.0 part per million precision.
Precision CNC axis calibration services ensure your machine tools deliver consistent accuracy and minimize unexpected downtime. Using Renishaw laser interferometry with NIST-traceable measurements accurate to 1.0 part per million, we verify positioning, repeatability, straightness, and squareness across all axes. Our calibration services identify hidden wear, alignment errors, and servo issues before they impact production quality, helping Portland OR and SW Washington manufacturers maintain tight tolerances and maximize equipment capability.

Comprehensive calibration solutions for linear axes, rotary tables, machine geometry, and performance verification using NIST-traceable laser measurement systems.
Laser interferometer verification of positioning accuracy, repeatability, straightness, and squareness across full axis travel with NIST-traceable measurements to 1.0 part per million precision.
Angular positioning accuracy and repeatability measurement using Renishaw's Rotary Calibration System to verify rotary tables, trunnions, and multi-axis machine alignment for precise machining operations.
Rapid machine health assessment using Renishaw QC20-W Ballbar to identify backlash, servo mismatch, axis reversal errors, squareness problems, and critical wear affecting circularity and overall accuracy.
Electronic level measurements detect pitch and roll errors in machine beds, guideways, and large structures, identifying alignment issues from installation, relocation, or foundation movement.
Flatness measurement and leveling verification using Moody Plot analysis to maintain accurate reference planes for inspection work and ensure consistent measurement reliability in production environments.
Hands-on training for Renishaw laser interferometer and ballbar systems, teaching proper setup, data collection, result interpretation, and troubleshooting techniques for maintenance teams and quality engineers.

We begin with a thorough evaluation of your CNC machine's current condition, reviewing maintenance history, operational concerns, and specific accuracy requirements. This assessment identifies priority axes and potential trouble areas that need focused attention during calibration.

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.
The five critical points of CNC axis calibration include: (1) Positioning accuracy—how closely the machine reaches commanded positions; (2) Repeatability—consistency returning to the same position multiple times; (3) Straightness—deviation from a straight line during axis travel; (4) Squareness—perpendicularity between axes; and (5) Angular accuracy—for rotary axes, how precisely the angle matches the commanded rotation. These measurements comprehensively evaluate machine geometric accuracy.
