Our Precision Testing Solutions

Comprehensive calibration and verification services that ensure equipment accuracy, eliminate unexpected downtime, and maintain production quality.

Linear Calibration

NIST-traceable laser interferometry verifies positioning accuracy, repeatability, straightness, and squareness to 1.0 parts per million. Identifies installation errors and hidden damage before they impact production quality across full axis travel.

Ballbar Testing

Quick machine health assessment using wireless QC20-W Ballbar to evaluate circularity and identify backlash, servo mismatch, reversal errors, and squareness problems. Validates service work and supports maintenance planning with minimal downtime.

Rotary Axis Verification

Measures angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using advanced calibration systems. Identifies mechanical wear, setup errors, and encoder issues affecting multi-axis machining performance.

Surface Plate Assessment

Expert leveling and flatness verification including Moody Plot measurement ensures accurate reference planes for inspection and layout work. Maintains measurement reliability and part accuracy as surface plates wear over time.

Electronic Leveling

Precision pitch and roll error detection for machine beds, guideways, and large structures. Identifies alignment issues from installation, relocation, or foundation movement that affect axis geometry and machining stability.

Technical Training

Hands-on instruction for CAM software, CNC operation, laser interferometry, and ballbar systems. Tailored sessions improve operator efficiency, reduce errors, and enable in-house diagnostics for maintenance teams and quality engineers.

Precision You Can Trust

NIST-Traceable Accuracy That Eliminates Unexpected Downtime

Sarkinen Calibrating goes beyond equipment maintenance to deliver comprehensive precision solutions that keep manufacturing operations running predictably. Our measurements achieve accuracy to 1.0 parts per million—well beyond the 10:1 ratio required for proper calibration—and are fully traceable to NIST and International Standards. We verify that new machines meet manufacturer specifications while under warranty, identify hidden installation damage before it impacts production, and provide the proof customers need that equipment can deliver as promised, every time.
