Our CNC Laser Calibration Services

We offer comprehensive precision measurement and calibration solutions to verify and maintain CNC machine accuracy across all critical axes and components.

Linear Calibration

Verify positioning accuracy, repeatability, straightness, and squareness across full axis travel using Renishaw's Laser Interferometer with NIST-traceable accuracy to 1.0 parts per million. Ideal for new machine verification and identifying alignment errors.

Ballbar Testing

Evaluate true circularity and identify critical wear issues including backlash, servo mismatch, axis reversal errors, and squareness problems using Renishaw's QC20-W Ballbar. Fast machine health snapshot with minimal downtime.

Rotary Axis Calibration

Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's Rotary Calibration System. Ensures motion matches programmed commands for multi-axis machining precision.

Electronic Leveling

Detect and correct pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal's Electronic Level. Critical for maintaining axis geometry and identifying installation or foundation issues.

Surface Plate Verification

Maintain reference plane accuracy through expert leveling and flatness verification including Moody Plot analysis. Ensures inspection and layout consistency as plates wear over time.

Calibration Training

Hands-on training for Renishaw Laser Interferometer and QC20-W Ballbar systems, plus CAM software and CNC operation. Empowers your team to perform in-house diagnostics and understand machine accuracy data.

Accuracy You Can Trust

NIST-Traceable Precision That Eliminates Production Surprises

Manufacturing precision isn't just about hitting tolerances—it's about predictable, consistent performance shift after shift. Our laser calibration services deliver measurements traceable to NIST and International Standards, exceeding the required 10:1 ratio for proper calibration. Whether you're verifying a new machine under warranty or troubleshooting accuracy drift, we identify hidden errors before they impact part quality. Founded by a former machine operator, we approach calibration as more than equipment maintenance—it's about keeping your production running efficiently with minimal disruption.

Larry

Founder

Larry's journey into precision calibration began on the shop floor as a machine operator, where he experienced firsthand the frustrations of unexpected downtime and accuracy drift. That perspective shaped his approach to building Sarkinen Calibrating—not as an equipment maintenance service, but as a solutions provider focused on increasing production quality and efficiency. He understands that calibration isn't just about numbers on a report; it's about keeping machines running predictably so operators can focus on making great parts. Larry built the business on the principle that accurate equipment shouldn't be a luxury—it should be the standard. His operator-first mindset continues to guide every calibration service, training session, and customer interaction, ensuring clients receive practical solutions that actually solve production challenges. For Larry, success means manufacturers never have to wonder if their machines will deliver the precision they promise.

Frequently Asked Questions

What is CNC laser calibration and why is it important?

CNC laser calibration uses precision laser interferometry to verify that your machine's actual movement matches its programmed commands. It measures positioning accuracy, repeatability, straightness, and squareness across all axes. This is critical because even new machines can have shipping damage or installation errors, and older machines develop wear over time. Without regular calibration, you're essentially guessing whether parts will meet specifications—calibration removes the guesswork and prevents costly scrap.
