Precision dynamic balance calibration ensures your rotating machinery operates smoothly, safely, and efficiently. Our NIST-traceable calibration services identify imbalance issues before they cause costly downtime, reducing vibration, extending equipment life, and maintaining production quality. From CNC spindles to rotary axes, we deliver measurements accurate to one millionth of an inch, helping Portland-area manufacturers maintain predictable operations and eliminate unexpected failures.
Comprehensive precision calibration solutions ensuring your rotating equipment operates at peak accuracy with minimal vibration and maximum reliability.
Verify angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's advanced measurement systems. Identify mechanical wear, setup errors, and encoder issues affecting multi-axis machining performance and part quality.
Achieve positioning accuracy to 1.0 parts per million using laser interferometry. Measure accuracy, repeatability, straightness, and squareness across full axis travel to verify manufacturer specifications and identify installation or shipping-related alignment issues.
Rapidly assess machine condition with Renishaw's QC20-W Ballbar. Evaluate circularity and detect backlash, servo mismatch, axis reversal errors, and squareness problems. Ideal for validating service work and troubleshooting accuracy issues.
Maintain surface plate accuracy through expert leveling and flatness verification using Moody Plot analysis. Ensure your reference planes remain reliable for inspection and layout work as plates naturally wear over time.
Detect and correct pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal's Electronic Level. Identify alignment issues from installation, relocation, or foundation movement affecting axis geometry.
Hands-on training for laser interferometry, ballbar systems, CAM software, and CNC operation. Learn proper setup, data interpretation, and troubleshooting techniques to perform in-house diagnostics and maximize machine capability.
Initial Assessment and Equipment Setup
We begin with a thorough evaluation of your equipment's current condition and calibration history. Our technicians strategically position precision measurement tools including laser interferometers, ballbar systems, or electronic levels depending on your specific machinery. This setup phase ensures optimal measurement accuracy and minimizes disruption to your Portland-area production schedule.

Founder
Larry brings a unique perspective to calibration services, having started his career as a machine operator before founding Sarkinen Calibrating. This hands-on production experience shapes his approach to every calibration project—he doesn't just see equipment maintenance, he sees opportunities to increase production quality and operational efficiency. Larry understands the pressures of meeting tight tolerances, the cost of unexpected downtime, and the importance of machines that perform exactly as promised. His operator-first philosophy has built Sarkinen Calibrating into Portland and SW Washington's trusted precision calibration provider, serving manufacturers who need NIST-traceable accuracy combined with practical solutions that keep production running smoothly. Larry's commitment to customer service and minimal disruption reflects his deep understanding of what matters most in a production environment.
