Ensure your CNC machines deliver precision with every operation. Sarkinen Calibrating provides comprehensive machine calibration services across Oregon, helping manufacturers eliminate unexpected downtime and maintain production quality. From laser interferometry to ballbar testing, our NIST-traceable measurements verify your equipment meets specifications while identifying issues before they impact your bottom line. Oregon's diverse manufacturing landscape—from Portland's aerospace sector to rural fabrication shops—demands reliable precision that keeps operations running smoothly.
Comprehensive precision measurement and verification services to keep your CNC equipment accurate, reliable, and production-ready.
Verify positioning accuracy, repeatability, straightness, and squareness across full machine travel using Renishaw Laser Interferometer with 1.0 PPM accuracy. NIST-traceable measurements identify alignment errors and hidden damage before they affect production quality.
Fast, effective machine health monitoring using Renishaw QC20-W Ballbar to evaluate circularity and identify backlash, servo mismatch, axis reversal errors, and squareness problems. Validates service work and supports maintenance planning.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's Rotary Calibration System. Identifies mechanical wear, setup errors, and encoder issues affecting multi-axis machining.
Detect and correct pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal Electronic Level. Identifies alignment issues from installation, relocation, or foundation movement affecting machine geometry.
Maintain reference plane accuracy through expert leveling and flatness verification including Moody Plot analysis. Ensures consistent inspection results and prevents measurement reliability issues as plates wear over time.
Hands-on instruction for Renishaw Laser Interferometer, QC20-W Ballbar systems, CAM software, and CNC operation. Tailored training helps teams perform in-house diagnostics, interpret results, and maximize machine capability.
Initial Assessment and Equipment Setup
Our technician arrives at your Oregon facility with calibrated Renishaw measurement systems and performs a thorough initial assessment of your machine's current condition, operating environment, and calibration history. We evaluate factors like foundation stability and thermal conditions that can affect measurement accuracy.

Founder
Larry's journey in precision manufacturing began on the shop floor as a machine operator, where he experienced firsthand the challenges that arise when equipment accuracy drifts. This perspective shaped his approach to calibration—it's never been just about maintaining equipment specs on paper. For Larry, calibration is about understanding the complete machining operation and identifying solutions that genuinely increase production quality and operational efficiency. He built Sarkinen Calibrating on the principle that effective calibration service requires both technical precision and practical manufacturing insight. Larry knows that when a machine operator questions their equipment's accuracy, it affects confidence, productivity, and part quality. His background gives him unique insight into how calibration impacts daily production realities—from setup time to scrap rates to customer confidence. This operator-first perspective continues to guide how Sarkinen Calibrating delivers service throughout Oregon, always focusing on solutions that make a real difference where it matters most: on the production floor.
How is a CNC machine calibrated?
CNC machine calibration uses precision measurement equipment like laser interferometers to verify positioning accuracy, repeatability, straightness, and squareness of each axis across its full travel. The process compares actual machine movement against programmed commands, identifies deviations, and documents performance against manufacturer specifications. Advanced systems measure to accuracies of 1.0 parts per million.
