Discover industry-leading test and measurement equipment manufacturers trusted by precision-driven operations worldwide. From laser interferometers to ballbar systems, learn which manufacturers deliver NIST-traceable accuracy, cutting-edge technology, and reliable performance for CNC calibration, metrology, and quality assurance applications that eliminate unexpected downtime and ensure consistent production quality.
Expert calibration services using industry-leading test and measurement equipment from top manufacturers, ensuring NIST-traceable accuracy for your operations.
Verify positioning accuracy to 1.0 parts per million using Renishaw's Laser Interferometer. Measure positioning accuracy, repeatability, straightness, and squareness across full axis travel with NIST-traceable results that exceed 10:1 calibration ratios.
Monitor CNC machine performance using Renishaw's QC20-W Ballbar system. Quickly identify backlash, servo mismatch, axis reversal errors, and squareness problems with wireless setup that minimizes downtime while delivering repeatable results.
Maintain surface plate accuracy through expert leveling and flatness verification with Moody Plot analysis. Ensure your reference planes continue providing reliable measurement standards for inspection and layout work as wear occurs over time.
Verify rotary axis accuracy using Renishaw's Rotary Calibration System. Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions to ensure motion matches programmed commands on multi-axis machines.
Identify and correct machine axis errors using Mahr-Federal's Electronic Level. Detect pitch and roll errors on machine beds, guideways, and large structures where angular deviations affect accuracy, especially after installation or relocation.
Hands-on training for Renishaw's Laser Interferometer, QC20-W Ballbar, CAM software, and CNC operation. Learn proper setup, data interpretation, and troubleshooting techniques to maximize equipment capability and perform in-house diagnostics.
Leading test and measurement manufacturers like Renishaw and Mahr-Federal provide the precision tools that keep production operations running predictably. When calibration equipment delivers accuracy to one millionth of an inch and measurements traceable to NIST standards, manufacturing facilities gain confidence that machines can deliver as promised, every time. The right equipment identifies errors before they become problems, verifies new machines meet specifications while under warranty, and provides the proof your customers need that quality is never compromised.
Manufacturing facilities rely on top-tier test equipment to maintain quality and minimize downtime across critical operations.
"I have worked with Mr Sarkinen on a job in Portland He is a Highly Skilled, Knowledgable Professional. I would definitely recomend him for all your Machine Tool Calibration Metrics. Sincerely Curtis Page Naughtellis CNC Service"
"As plant manager at Triad, I am always looking for ways of testing and measuring the condition of our large machines. Our outside repair tech suggested that I have Sarkinen Calibrating run their Ball Bar Test on all of our machines to show if we had any critical wear issues..."
"This guy knows his stuff. Would definately recommend! Friendly good people!"

Founder
Larry's journey into precision calibration didn't start in a laboratory—it started on the shop floor as a machine operator. That hands-on experience gave him a perspective most calibration providers lack: he understands what it's like when equipment fails mid-production, when tolerances drift unexpectedly, and when downtime costs more than just time. Before founding Sarkinen Calibrating, Larry worked directly with CNC machines, experiencing firsthand the frustration of accuracy issues and the relief of properly calibrated equipment. That operator's mindset shaped his approach to calibration—it's never just about checking boxes on a maintenance schedule. It's about understanding how calibration impacts production quality, efficiency, and profitability. Larry built Sarkinen Calibrating to provide solutions that actually solve problems, not just generate reports. His focus remains on helping manufacturing operations achieve predictable performance, minimize unexpected downtime, and maintain the confidence that their machines can deliver as promised, every single time.
What is the most accurate measurement tool?
Laser interferometers provide the highest accuracy for linear measurement, with systems like Renishaw's achieving accuracy to 1.0 parts per million (one millionth of an inch per inch). These tools are traceable to NIST and international standards, making them ideal for verifying CNC machine positioning, straightness, and squareness with precision that exceeds required 10:1 calibration ratios.
