Our Industrial Calibration Services

Complete precision calibration solutions for manufacturing equipment, from laser interferometry to specialized training programs.

Linear Calibration

Verify positioning accuracy to 1.0 parts per million using Renishaw's Laser Interferometer. Measure accuracy, repeatability, straightness, and squareness across full axis travel with NIST-traceable results that identify shipping damage and installation errors before they impact production.

Ballbar Testing

Quick machine health assessment using Renishaw's QC20-W Ballbar to evaluate circularity and identify backlash, servo mismatch, axis reversal errors, and squareness problems. Validate service work and support maintenance planning with wireless setup minimizing downtime.

Rotary Axis Calibration

Measure angular positioning accuracy, repeatability, and alignment using Renishaw's Rotary Calibration System. Identify mechanical wear, setup errors, or encoder issues affecting multi-axis machining to ensure motion matches programmed commands.

Surface Plate Verification

Maintain reference plane accuracy through expert leveling and flatness verification including Moody Plot analysis. Monitor wear over time to ensure consistent inspection results and prevent changes in part accuracy and measurement reliability.

Electronic Leveling

Detect and correct pitch and roll errors using Mahr-Federal's Electronic Level. Evaluate machine beds, guideways, and large structures to identify alignment issues from installation, relocation, or foundation movement affecting machining stability.

Calibration Training Programs

Hands-on training for CAM software, CNC operation, and Renishaw measurement systems. Learn proper setup, data interpretation, and troubleshooting techniques to perform in-house diagnostics and maximize equipment capability.

Service Process

Our 5-Step Calibration Process

Initial Assessment and Equipment Setup

We begin by evaluating your equipment condition and production requirements. Our technicians arrive with calibrated measurement systems including Renishaw laser interferometers and ballbar equipment, setting up with minimal disruption to your Portland-area operations. We review machine history, recent performance issues, and warranty status to customize our approach.

Larry

Founder

Larry's journey into calibration services began on the manufacturing floor as a machine operator, giving him a unique perspective that shapes every service Sarkinen Calibrating provides today. Unlike calibration specialists who approach equipment as technical specifications to be measured, Larry understands the real-world pressures of production schedules, quality requirements, and the cost of unexpected downtime. This hands-on foundation drives his commitment to looking beyond routine equipment maintenance to deliver solutions that genuinely increase production quality and efficiency. His operator background means he speaks the language of manufacturing professionals, understands what keeps production managers up at night, and designs calibration services that minimize disruption while maximizing reliability. Larry built Sarkinen Calibrating on the principle that precision measurement should serve production goals, not just check compliance boxes, and that philosophy continues to guide every customer interaction and service delivery.

Frequently Asked Questions

What is industrial calibration and why is it important?

Industrial calibration verifies that your manufacturing equipment performs within specified tolerances by comparing measurements against NIST-traceable standards. Regular calibration prevents unexpected downtime, ensures part quality, validates warranty claims, and provides documentation that your machines deliver promised accuracy. It identifies wear and alignment issues before they become costly production problems.
