Precision CNC Machining Company with Fast Turnaround

Precision CNC machining refers to computer-controlled manufacturing processes that produce parts with extremely tight tolerances, often measured in microns. The 'precision' aspect depends on both the machine's capability and its calibration status. Even high-quality CNC machines require regular calibration to maintain accuracy over time, as wear, thermal expansion, and mechanical stress affect positioning and repeatability. Precision calibration services verify that machines can consistently hold the tolerances required for critical components.

Calibration frequency depends on machine usage, part tolerance requirements, and production volume. High-precision work typically requires quarterly or semi-annual calibration, while general machining may only need annual verification. New machines should be calibrated immediately after installation to verify warranty specifications. Ballbar testing can be performed more frequently as a quick health check between comprehensive laser calibrations.

Renishaw laser interferometer systems provide measurement accuracy to 1.0 parts per million, which equals one millionth of an inch per inch of travel. This exceeds the 10:1 ratio required for proper calibration and provides NIST-traceable documentation. This level of accuracy ensures you can confidently verify machine performance and prove capability to customers requiring precision components.

A comprehensive laser interferometer calibration typically takes 4-8 hours depending on machine size and axis count. Ballbar testing is much faster, usually 1-2 hours, making it ideal for quick diagnostics. Our local service advantage means we can often schedule same-day or next-day appointments to minimize production disruption compared to waiting for out-of-area providers.

You receive complete NIST-traceable reports showing positioning accuracy, repeatability, straightness, and squareness for each axis. Reports include graphical data, measured errors, and clear pass/fail status against specifications. This documentation supports ISO quality systems, customer audits, and warranty claims. We also provide actionable recommendations for addressing any identified issues.

Yes. Regular calibration identifies developing problems like backlash, servo mismatch, and mechanical wear before they cause part rejections or machine failures. Predictive monitoring catches issues early when they're easier and less expensive to fix. This eliminates surprise downtime and allows you to schedule maintenance during planned breaks rather than emergency production stops.

Yes, while we're based in Portland OR and SW Washington with faster local response times, we also provide calibration services to out-of-area customers. Our laser interferometer and ballbar systems are portable, allowing us to serve facilities throughout Oregon, Northern California, and Idaho. Contact us to discuss your location and scheduling requirements.

First, document all findings while the machine is still under warranty—this is critical. Calibration often reveals shipping damage or installation errors that manufacturers will address under warranty if caught early. We provide detailed reports showing exactly where specifications aren't met, which supports warranty claims. We can also work with your machine service provider or manufacturer to verify corrections after adjustments are made.
