The Renishaw XR-20 rotary axis calibrator is designed to calibrate rotary axes with high precision. This tool is used for:

Renishaw XR-20 Rotary Axis Calibrator

Overview:
The XR-20 is a high-precision rotary axis calibrator designed to verify and calibrate rotary tables and 4th/5th axes on CNC machines, ensuring angular positioning accuracy.

Key Specifications:

• Accuracy: ±1 arc second

• Resolution: 0.1 arc second

• Rotation Range: 360° continuous

• Mounting: Magnetic base for flexible setup

• Compatible Systems: Works with Renishaw XL-80 and CARTO software

Accuracy Test & Correction Procedure:

1. Mount XR-20 on the rotary axis using its magnetic base.

2. Connect with XL-80 interferometer system.

3. Create a test program using CARTO software to rotate the axis in defined increments.

4. Measure angular positioning error, repeatability, and backlash.

5. Analyze results and apply rotary axis compensation in the CNC controller.

6. Re-test to confirm improved rotary accuracy.

Result:
Precise rotary axis calibration, enhanced contouring accuracy, and compliance with ISO/VDI angular positioning standards.
