The Renishaw XR20 rotary calibrator provides up to ±1 arc second accuracy and is used in conjunction with the Renishaw XL-80 and XM-60 laser systems providing highly accurate, repeatable rotary axis calibration for stages, jigs and machine tools. 

The Renishaw XR20 consists of an integrated angular retroreflector mounted on a precision servo-controlled axis. The angular position of the axis, and the optics relative to the main body housing, is controlled by a very high accuracy encoder system with the scale directly machined on the main bearing.

• Flexible and light weight – designed for single handed easy fitment to a wide variety of rotary tables, lathes and other rotary axes
• Flexible mounting via the ring adaptor plate enables the XR20 to be fitted to rotary tables with unsuitable centre recesses. It can also be used to secure the XR20 to the chuck (lathe) adaptor and custom mounts.
• High accuracy - ±1 arc second using XL-80 or ±1.2 arc second using XM-60. (See error budget and uncertainty calculation below for further details).
• Rapid testing - quick test setup and fast data capture
• Wireless operation – powered by rechargeable batteries and integrated wireless connection using Bluetooth® communicationBuilt-in alignment targets – minimizes measurement errors during setup
• Auto calibration – pre-measurement calibration cycle compensates for angular alignment errors
• Pre-test cycles – automatic direction and feedrate detection
• Feedrate - speeds of up to 10 rpm
• Utilizes the CARTO software suite featuring three applications:
• Capture to collect data and generate part programs.
• Explore to provide powerful analysis and create reports to international standards.
• Compensate to generate compensation files for improved positioning accuracy.
