When production schedules demand flawless accuracy and rapid delivery, Sarkinen Calibrating delivers precision turning services that keep your operations moving forward. Our NIST-traceable calibration ensures every turned component meets exact specifications, eliminating costly rework and unexpected downtime. Whether you're producing high-tolerance shaft work, rotary components, or complex turned parts, our fast turnaround times and measurement accuracy to 1.0 parts per million guarantee your precision turning operations deliver consistent, reliable results every time.
Comprehensive calibration solutions that ensure your turning operations deliver consistent accuracy, eliminate errors, and maintain production quality.
Verify angular positioning accuracy, repeatability, and alignment of rotary tables and turning centers using Renishaw's advanced calibration system. Identify mechanical wear, setup errors, and encoder issues before they impact your turned parts.
NIST-traceable laser interferometer measurements verify positioning accuracy, repeatability, straightness, and squareness across full axis travel to 1.0 part per million. Ensures your turning operations meet manufacturer specifications and maintain tight tolerances.
Electronic leveling detects pitch and roll errors in turning center beds, guideways, and structures. Corrects alignment issues from installation or foundation movement that affect turned part consistency and surface finish quality.
Quick evaluation of turning center health using Renishaw's QC20-W Ballbar. Identifies backlash, servo mismatch, axis reversal errors, and squareness problems that compromise circularity in turned components.
Maintain accurate reference planes for inspection and setup of turned parts. Flatness verification and Moody Plot analysis ensure your measurement fixtures provide reliable quality control data.
Hands-on instruction for CNC turning machine operation, calibration system use, and understanding how machine geometry affects turned part quality. Tailored to your equipment and skill level.
We begin with a thorough evaluation of your turning center's current condition, reviewing maintenance history, recent production issues, and specific accuracy requirements. This assessment identifies which calibration tests will deliver the most value for your operation and helps establish baseline performance metrics before any measurements begin.

"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.
Precision turning is a machining operation where material is removed from a rotating workpiece using a cutting tool to create cylindrical shapes, tapers, threads, or contoured surfaces with extremely tight dimensional tolerances—often within microns. It requires accurately calibrated machines to maintain consistent diameter, concentricity, and surface finish across production runs, ensuring every turned component meets exact specifications.
