Precision CNC equipment demands proactive maintenance to maintain accuracy and prevent costly downtime. Sarkinen Calibrating delivers comprehensive preventive service programs that keep Portland OR and SW Washington manufacturing operations running with NIST-traceable accuracy. Our systematic approach identifies wear patterns and calibration drift before they impact production quality, ensuring your machines deliver consistent results shift after shift.
Comprehensive precision measurement and calibration solutions that maintain equipment accuracy and eliminate unexpected downtime for manufacturing operations.
Verify positioning accuracy to 1.0 part per million using Renishaw Laser Interferometer. Measure accuracy, repeatability, straightness, and squareness across full axis travel with NIST-traceable results that exceed 10:1 calibration requirements.
Quick machine health assessment using Renishaw QC20-W Ballbar to identify backlash, servo mismatch, axis reversal errors, and squareness problems. Wireless setup minimizes downtime while validating machine condition and recent service work.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's Rotary Calibration System. Identify mechanical wear, setup errors, or encoder issues affecting multi-axis machining accuracy.
Expert leveling and flatness verification including Moody Plot measurement to ensure accurate reference planes for inspection and layout work. Maintain measurement reliability and part accuracy as surface plates wear over time.
Detect pitch and roll errors using Mahr-Federal Electronic Level to evaluate machine beds, guideways, and large structures. Identify alignment issues from installation, relocation, or foundation movement affecting machining stability.
Hands-on training for Renishaw Laser Interferometer, QC20-W Ballbar systems, CAM software, and CNC operation. Learn proper setup, data interpretation, and troubleshooting to perform in-house diagnostics and maximize equipment capability.
Initial Baseline Assessment & Documentation
We establish comprehensive baseline measurements of your CNC equipment using laser interferometry and ballbar testing. This creates a performance fingerprint documenting accuracy, repeatability, and geometric characteristics. Portland-area manufacturers benefit from rapid initial assessment scheduling that minimizes production interruption while establishing the foundation for ongoing precision monitoring.

Founder
Larry built Sarkinen Calibrating from his experience as a machine operator, bringing a unique perspective to precision measurement services. Unlike calibration providers who focus solely on equipment specifications, Larry approaches every job by understanding how calibration impacts actual production operations. His background operating CNC machines gives him insight into the real-world challenges manufacturers face—recognizing that accuracy problems often reveal themselves in subtle ways during production runs. This operator's perspective shapes how Sarkinen Calibrating delivers service: quickly identifying issues, minimizing production disruption, and providing practical solutions that improve both quality and efficiency. Larry's philosophy has always been clear—calibration isn't just about maintaining equipment, it's about enabling consistent, predictable manufacturing operations that deliver quality parts every time.
What is CNC machine maintenance?
CNC machine maintenance includes preventive calibration, precision measurement verification, mechanical inspection, and systematic testing to ensure equipment maintains accuracy and reliability. It involves checking positioning accuracy, geometric errors, rotary axis alignment, and overall machine condition using laser interferometry, ballbar testing, and electronic leveling to identify wear patterns before they impact production quality.
