Rotary axis calibration system XR20

for machinesautomatichigh-precision

Rotary axis positioning is critical to overall machine accuracy Rapid calibration using XR20 provides up to ±1 arc second accuracy: The XR20 rotary axis calibrator works in conjunction with XL-80 and XM-60 laser systems. It 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. Features and benefits: Flexible and light weight – designed for single handed easy fitment to a wide variety of rotary tables, lathes and other rotary axes 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® communication Built-in alignment targets – minimises 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 Easy to use mounting options: Mounting the XR20 to rotary axes is simplified using a range of modular mounts to suit different applications. Standard mounting: Centration on the axis is typically very simple, using the markings around the circumference of the mounting ring and the centration aid.
