Achieve unmatched accuracy in your metal turning operations with precision-calibrated CNC machining solutions. Our NIST-traceable calibration services ensure your turning centers deliver consistent, high-quality results while minimizing unexpected downtime. From verifying axis positioning to rotary calibration, we optimize your equipment's performance so every part meets specifications the first time.
Comprehensive calibration and verification services to ensure your CNC turning operations deliver maximum accuracy and reliability.
Verify positioning accuracy, repeatability, and straightness of CNC turning center axes using laser interferometry with 1.0 PPM precision. NIST-traceable measurements identify alignment errors before they affect part quality and production efficiency.
Ensure angular positioning accuracy and repeatability of C-axis and live tooling rotary components using Renishaw calibration systems. Detect encoder issues, mechanical wear, and setup errors that impact multi-axis turning operations.
Quickly evaluate overall CNC turning center health using wireless ballbar technology. Identify backlash, servo mismatch, axis reversal errors, and squareness problems that compromise circularity and dimensional accuracy in turned parts.
Detect and correct pitch and roll errors in machine beds and guideways using electronic leveling. Proper leveling maintains stable axis geometry, especially critical for long-bed turning centers and machines after relocation or foundation settling.
Maintain accurate reference planes for turning center setup and part inspection through flatness verification and Moody Plot analysis. Ensure consistent measurement reliability and part accuracy as surface plates wear over time.
Hands-on training for CNC turning machine operation, CAM software, and calibration equipment use. Improve efficiency, reduce setup errors, and help your team understand how machine geometry affects turning quality and production outcomes.
Your CNC turning operations demand precision at the micron level, and even minor axis errors can create costly scrap and rework. Our calibration services verify that your turning centers perform exactly as programmed, with measurements accurate to one millionth of an inch per inch. Whether you're producing high-volume production runs or complex turned components, we identify hidden errors caused by shipping, installation, wear, or thermal drift before they impact your bottom line. With faster local response times and comprehensive diagnostic capabilities, we keep your turning operations running predictably.
Leading manufacturers rely on our calibration expertise to maintain turning center accuracy and eliminate unexpected downtime.
"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!"
"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..."

Founder
Larry's journey from machine operator to calibration service founder gives him a unique perspective that goes far beyond equipment maintenance. Having operated CNC machines firsthand, he understands the real-world production challenges manufacturers face daily—the frustration of unexpected downtime, the cost of scrap from axis errors, and the pressure to maintain tight tolerances. This operator-level experience drives his approach to calibration: it's not just about verifying numbers, it's about delivering solutions that genuinely increase production quality and efficiency. Larry built Sarkinen Calibrating on the principle that precision calibration should eliminate problems before they disrupt operations, providing manufacturers with the confidence that their equipment will perform exactly as promised. His hands-on background means he approaches every calibration with practical insight into how machine accuracy directly impacts your production floor, helping you achieve highly predictable operation with minimal disruption.
