Angular Positioning Accuracy
Precise measurement of rotary table and trunnion positioning to verify motion matches programmed commands, ensuring multi-axis machining accuracy across the full rotation range.
Precision rotary axis calibration ensures your multi-axis CNC machines deliver the accuracy your production demands. Using Renishaw's advanced Rotary Calibration System, we measure angular positioning, repeatability, and alignment to identify mechanical wear, setup errors, and encoder issues before they compromise part quality. Our NIST-traceable measurements help Portland and SW Washington manufacturers maintain consistent machining performance and eliminate costly production errors.
Comprehensive rotary component testing and verification to ensure your multi-axis CNC machines maintain optimal accuracy and performance.
Precise measurement of rotary table and trunnion positioning to verify motion matches programmed commands, ensuring multi-axis machining accuracy across the full rotation range.
Evaluate the consistency of rotary axis positioning over multiple cycles to identify wear patterns, encoder drift, or mechanical issues affecting production reliability.
Comprehensive alignment analysis of rotary components to machine axes, detecting installation errors and misalignment that compromise part geometry and surface finish quality.
Systematic identification of bearing wear, backlash, and mechanical degradation in rotary systems before they cause production quality issues or unexpected machine downtime.
Detailed evaluation of rotary encoder performance to detect signal errors, resolution issues, or calibration drift that affect positioning accuracy in multi-axis operations.
Complete documentation with measurements traceable to NIST and International Standards, providing verifiable proof of rotary axis accuracy for quality audits and customer requirements.
Modern CNC machines increasingly rely on rotary axes for complex part geometry, but improper calibration can undermine overall machine accuracy. Our Renishaw Rotary Calibration System delivers precise measurements of angular positioning, repeatability, and alignment—identifying mechanical wear, setup errors, and encoder issues before they impact your production. With local service across Portland and SW Washington, we provide faster response times than distant providers while maintaining full NIST traceability. Whether verifying new equipment or troubleshooting accuracy problems, our rotary axis calibration ensures your multi-axis machines perform exactly as programmed.

What is rotary axis calibration and why is it important?
Rotary axis calibration verifies the angular positioning accuracy, repeatability, and alignment of rotary tables and trunnions on multi-axis CNC machines. As these components become more common on modern machine tools, proper calibration is essential because even small errors in rotary positioning can significantly impact overall machine accuracy and part quality. Calibration identifies mechanical wear, setup errors, and encoder issues before they cause production problems.
