Achieve unmatched machining precision with laser interferometry accurate to 1.0 parts per million—one millionth of an inch per inch. Our NIST-traceable CNC laser measurement solutions identify hidden errors, verify machine specifications, and eliminate costly production defects before they impact your bottom line. From linear calibration to rotary axis verification, we deliver the diagnostic clarity manufacturers need to maintain competitive quality standards.
Comprehensive precision measurement solutions using advanced laser technology to verify, calibrate, and optimize CNC machine performance across all critical axes.
Verify positioning accuracy, repeatability, straightness, and squareness across full axis travel using laser interferometry accurate to 1.0 parts per million. NIST-traceable measurements identify shipping damage, installation errors, and wear before they compromise part quality.
Quickly evaluate machine health using Renishaw's QC20-W Ballbar to detect backlash, servo mismatch, axis reversal errors, and squareness issues. Wireless setup delivers fast circularity analysis with minimal production disruption.
Measure angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions using Renishaw's Rotary Calibration System. Identify encoder issues, mechanical wear, and setup errors affecting multi-axis machining precision.
Detect pitch and roll errors in machine beds, guideways, and large structures using Mahr-Federal's Electronic Level. Quickly identify alignment issues from installation, relocation, or foundation movement that compromise axis geometry.
Maintain measurement reference accuracy through expert leveling and flatness verification using Moody Plot analysis. Ensure surface plates continue providing reliable reference planes as they wear over time.
Hands-on instruction for laser interferometer operation, ballbar testing, CAM software, and CNC machine operation. Tailored to your equipment and skill level to improve efficiency and maximize machine capability.
Pre-Measurement Equipment Assessment and Planning
We begin by reviewing your machine specifications, production challenges, and accuracy requirements. Our team evaluates machine type, axis configuration, and operating environment to select the appropriate measurement methodology—whether laser interferometry, ballbar testing, or electronic leveling. This planning phase ensures we arrive with the correct equipment and minimize disruption to your production schedule.

"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..."
"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"
"This guy knows his stuff. Would definately recommend! Friendly good people!"

Founder
Larry's journey from machine operator to calibration service founder gives Sarkinen Calibrating a unique perspective on manufacturing precision. His hands-on machining background means he understands that calibration isn't just about numbers on a report—it's about keeping production running smoothly and parts within tolerance. Larry built Sarkinen Calibrating on the principle that effective calibration service requires understanding the operational realities manufacturers face every day. His operator experience informs every service approach, focusing on practical solutions that increase production quality and efficiency rather than simply checking boxes. This perspective has shaped the company's commitment to minimal disruption, predictable maintenance schedules, and clear diagnostic reporting that maintenance teams can actually use. Larry's vision transformed calibration from routine equipment maintenance into a strategic tool for competitive manufacturing quality.
Is the laser measuring tool worth it?
Absolutely. Laser measurement systems provide accuracy to 1.0 parts per million, identifying hidden machine errors that cause scrap, rework, and unexpected downtime. For precision manufacturers, the cost of a single calibration service is typically recovered by preventing just one major production issue or validating warranty claims on new equipment.
