Expert Quick Turn Precision Machining Services

Precision machining is the process of removing material from a workpiece using CNC-controlled machines to achieve extremely tight dimensional tolerances—often measured in thousandths or even millionths of an inch. This level of accuracy requires properly calibrated equipment that can consistently position cutting tools exactly where programmed, which is why regular verification of machine accuracy is essential for maintaining precision machining capabilities.

High precision machining refers to manufacturing operations requiring tolerances typically tighter than ±0.001 inches (±0.025mm), often reaching ±0.0001 inches or better. These applications—common in aerospace, medical devices, and advanced manufacturing—demand equipment verified to perform within extremely narrow accuracy windows. Calibration services using laser interferometry ensure machines maintain the positioning accuracy needed for high precision work.

For quick-turn precision machining, we recommend calibration verification every 6-12 months for high-volume production machines, or annually for lower-volume equipment. However, calibration should also be performed after machine relocation, significant repairs, collision events, or whenever part quality issues suggest accuracy problems. New machines should be verified while still under warranty to document baseline performance.

Our Renishaw Laser Interferometer delivers measurements accurate to 1.0 parts per million—equivalent to one millionth of an inch per inch of travel. This exceeds the industry-standard 10:1 ratio required for proper calibration, and all measurements are fully traceable to NIST and International Standards, providing documentation that satisfies quality system requirements and customer audits.

Most calibration services can be completed in 2-6 hours depending on machine size, number of axes, and specific tests required. Ballbar testing is particularly fast, often completed in under an hour, making it ideal for quick performance verification. We schedule services to minimize production disruption and can often work during shift changes or off-hours to accommodate tight manufacturing schedules.

Absolutely. Verifying new machines while under warranty is one of our most valuable services. Shipping and installation often introduce alignment errors or hidden damage that may not be immediately obvious. Our NIST-traceable measurements clearly document whether equipment meets manufacturer specifications, providing the proof needed to address issues with the manufacturer before warranty expires.

We primarily serve Portland OR and SW Washington, where our local presence means significantly faster response times than out-of-area calibration providers. This is particularly valuable for quick-turn operations that can't afford extended equipment downtime. We also offer services to customers outside this primary service area when needed, though response times may be longer.

Yes, every calibration service includes comprehensive documentation showing measurement results, deviations from specifications, and NIST traceability. These reports satisfy ISO, AS9100, and other quality system requirements, and provide the evidence needed for customer audits or warranty claims. We clearly identify any issues found and provide specific recommendations for correction when needed.
