Expert Industrial Calibration Services in Washington State

Calibration should be performed by trained professionals using precision measurement equipment traceable to national standards like NIST. Sarkinen Calibrating's technicians are experienced in using advanced systems like Renishaw's Laser Interferometer and Ballbar to deliver accurate, reliable calibration results that meet industry requirements and support quality assurance programs.

Most manufacturers calibrate CNC machines annually as part of preventive maintenance. However, calibration frequency depends on usage intensity, part tolerance requirements, and whether machines have been relocated or serviced. High-precision operations may require more frequent verification, while newer machines should be calibrated while under warranty to identify any shipping or installation issues.

NIST traceability means calibration measurements are linked through an unbroken chain to standards maintained by the National Institute of Standards and Technology. This provides documented proof that your equipment measurements are accurate and reliable, which is essential for quality certifications, customer audits, and ensuring your parts meet specifications consistently.

Service time varies by equipment type and test scope. Ballbar testing typically takes 1-2 hours, while comprehensive laser interferometry of multiple axes may require 4-6 hours. We work efficiently to minimize production disruption and can often schedule service during planned downtime or off-shift hours to accommodate your operations.

Our detailed calibration reports include measurement data for positioning accuracy, repeatability, straightness, and squareness for each axis tested. Reports clearly identify any deviations from specifications, provide graphical analysis of results, confirm NIST traceability, and include recommendations for addressing any issues discovered during testing.

While calibration requires dedicating the machine for testing, we work with your schedule to minimize impact. Many customers prefer off-shift or weekend service. We can also coordinate with planned maintenance windows or perform quick ballbar checks during shorter production breaks to monitor machine health without extended downtime.

Yes, we understand that unexpected accuracy problems can halt production. As a Washington-based provider, we offer faster emergency response than out-of-area companies. Contact us when you suspect machine accuracy issues, and we'll prioritize scheduling to diagnose problems quickly and get your equipment back to producing quality parts.

Sarkinen Calibrating primarily serves Washington State, Portland OR, and Northern California, with local presence providing faster response times than distant providers. We can also accommodate out-of-area service requests for customers who need our specialized expertise and NIST-traceable precision measurement capabilities.
