XR20-W rotary axis calibrator

XR20-W allows the measurement of rotary axis positional accuracy to within 1 arc second. Totally wireless operation and modular mounting systems ensure suitability for a wide range of machines. 

Optional software allows operation 'off-axis', essential for many 5 axis machines.

The XR20-W addresses the need for quick and easy testing on a wide range of machines and axis types. It does this by keeping all the features that made its RX10 predecessor a success but adding much simpler set up and operation.

Features and benefits

XR20-W rotary axis calibrator modular mounting

Automated calibration - The XR20-W is motorised and data capture is synchronised to axis movement, i.e. no operator intervention required during data capture.

High accuracy and repeatability - Measurement accuracy of ±1 arc second. All Renishaw systems are factory calibrated and delivered with traceable certification.

Use of Renishaw laser system - Provides a high integrity, non-contact reference measurement, remote from the axis under test.

The features above have been carried across from RX10, however the totally new design of XR20-W delivers many additional benefits:

Wireless operation

  • Lithium batteries and Bluetooth® communications give truly wireless operation
  • Provides for easier and quicker set up and avoids issues with trailing cables, eliminating the safety hazard these create

Flexible mounting system

  • The measurement system is now separate from the mounting system
  • This modular approach allows far simpler and quicker set-up and can be configured for a wide variety of rotary tables, lathes and other rotary axes

 Compact and light weight

  • Handling and fixing on machine can be achieved single handed
  • Easy cost effective transportation
  • Clearance issues on machine minimised
Off axis software

 Off axis capability

  • Off axis rotary software* allows use of XR20-W in many machine configurations where it is difficult to mount the system directly on the machines rotary axis pivot point
  • Provides a solution for testing many five axis machines

  * When used with suitable mounting bracket

New data collection software

  • RotaryXL enables quicker and more consistent test set up to give faster test results with increased confidence

Integrated target and alignment optics

  • Factory set alignment of retro-reflectors to XR20-W measurement axis minimises alignment and resulting measurement errors
  • A simple optical alignment aid helps minimise measurement errors. Alignment adjustments can even be made via software, providing quicker and safer working for the operator

Extended auto calibration and pre-test cycles

  • Pre-measurement calibration cycle compensates for remaining angular alignment errors
  • Data sampling during test overrun detects and sets axis direction sense and axis feedrate

Servo controlled drive

  • Rotary axis measurement speeds for larger angles (›5°) of up to 10 rpm
  • Uses unique, integrated rotary encoder technology

RX10 to XR20-W upgrade

XR20-W superseded the RX10 calibrator system in 2011. We are sure many RX10 users would like to benefit from the additional benefits of XR20-W and the value it can add to their business. To make that purchasing decision a lot easier, very attractive discounts are available, subject to return of your current RX10.

If you factor in the cost of repairing or recalibrating your current RX10, then justifying XR20-W purchase may be easier than you think.
