Our Calibration Services

Comprehensive precision calibration solutions from linear measurement to rotary axis verification, ensuring your equipment operates at peak accuracy.

Linear Calibration

Verify positioning accuracy to 1.0 part per million using Renishaw Laser Interferometer, fully traceable to NIST standards. Measure accuracy, repeatability, straightness, and squareness across full axis travel to identify installation errors or hidden damage before production impact.

Ballbar Testing

Fast machine health evaluation using Renishaw QC20-W Ballbar to identify backlash, servo mismatch, axis reversal errors, and squareness problems. Quick wireless setup validates service work and supports maintenance planning with minimal downtime.

Rotary Axis Calibration

Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's Rotary Calibration System. Identify mechanical wear, setup errors, or encoder issues affecting multi-axis machining performance.

Surface Plate Verification

Expert leveling and flatness verification including Moody Plot measurement to maintain accurate reference planes. Monitor surface plate wear over time to ensure consistent inspection results and maintain production part accuracy.

Electronic Leveling

Detect pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal Electronic Level. Identify alignment issues from installation, relocation, or foundation movement that affect axis geometry and machining stability.

Calibration Training

Hands-on training for Renishaw systems, CAM software, and CNC operation. Learn proper setup, data interpretation, and troubleshooting techniques tailored to your equipment and skill level to maximize machine capability and reduce errors.

Built For Accuracy

NIST-Traceable Accuracy That Eliminates Production Surprises

We deliver calibration services that go beyond basic compliance—our measurements provide proof your equipment performs exactly as promised. With accuracy to 1.0 parts per million and full NIST traceability, we help you verify new machine warranties, identify hidden issues before they impact quality, and maintain predictable operations with minimal disruption. Founded by a former machine operator, we understand production realities and deliver solutions that actually increase efficiency.

Larry

Founder

Larry's journey into calibration services began on the shop floor as a machine operator, where he experienced firsthand the frustration of unexpected equipment failures and quality issues caused by undetected calibration drift. That hands-on perspective shaped his entire approach to building Sarkinen Calibrating—he knew the industry needed more than just equipment maintenance; it needed real solutions that prevent production problems before they happen. Today, Larry brings that unique operator's viewpoint to every calibration project, focusing on what actually matters for production quality and operational efficiency. His commitment goes beyond delivering accurate measurements—it's about helping manufacturing teams achieve highly predictable operations with minimal disruption, giving them confidence that their machines can deliver as promised, every single time. Larry's vision transformed his early machine shop experience into a calibration service that truly understands production realities and solves the problems operators face daily.
