Maintain peak CNC machine performance with professional Renishaw Ballbar testing from Sarkinen Calibrating. Our wireless QC20-W Ballbar system quickly identifies critical wear, backlash, servo mismatch, and squareness issues before they impact your production quality. With NIST-traceable accuracy and same-day service across Portland and SW Washington, we help you eliminate unexpected downtime and verify machine condition with confidence.
Comprehensive CNC machine diagnostics using advanced Renishaw technology to ensure optimal performance and identify issues before they impact production.
Evaluate true circularity and overall machine health by measuring how accurately your CNC machine executes programmed circular paths. Identifies positioning errors, backlash, and servo performance issues that affect part quality.
Fast, wireless ballbar testing provides a comprehensive snapshot of CNC machine condition. Detects critical wear patterns, axis alignment problems, and mechanical issues that lead to unexpected downtime and scrap parts.
Pinpoint servo mismatch, excessive backlash, and axis reversal errors that compromise machining accuracy. Our testing reveals mechanical wear and control system issues before they escalate into costly production problems.
Verify that machine axes remain properly squared to each other, ensuring consistent part geometry. Squareness errors accumulate during complex operations and directly impact dimensional accuracy across your production runs.
Confirm that recent machine repairs, alignments, or upgrades have restored expected performance levels. Ballbar testing provides objective proof that service work was completed successfully and your machine is production-ready.
Establish baseline machine performance and track changes over time to support predictive maintenance strategies. Regular ballbar testing helps schedule service before problems occur, reducing emergency repairs and unplanned downtime.
Pre-Test Machine Assessment
We review your machine's service history, current performance concerns, and production requirements. This helps us focus testing on the most critical areas and understand what accuracy standards your Portland or SW Washington operation needs to maintain.

Founder
Larry founded Sarkinen Calibrating after years of hands-on experience as a machine operator, giving him unique insight into the real-world challenges manufacturers face on the shop floor. He recognized that equipment calibration wasn't just about meeting specifications—it was about helping production teams maintain quality, avoid costly surprises, and operate with confidence. That operator's perspective shapes every service Sarkinen Calibrating provides. Larry built the company on the principle that calibration should deliver practical solutions that increase production quality and efficiency, not just generate paperwork. His approach focuses on understanding each customer's specific machining operations and providing testing services that directly support their production goals. Today, Sarkinen Calibrating serves Portland OR and SW Washington with comprehensive machine accuracy services, helping manufacturers keep their equipment running reliably and their output meeting demanding tolerances.
What is the purpose of ball bar test?
The ballbar test evaluates CNC machine accuracy by measuring how precisely the machine executes programmed circular paths. It quickly identifies critical issues like backlash, servo mismatch, squareness errors, and mechanical wear that affect part quality. This diagnostic tool provides a fast, comprehensive snapshot of overall machine health and performance.
