Renishaw equips updated XR20-W rotary axis calibrator with RotaryXL off-axis rotary software
1 min read
The updated Renishaw XR20-W rotary axis calibrator launched at the end of 2011, which provided easier set-up and operation in a smaller unit, has now had its application flexibility further extended by the addition of RotaryXL off-axis rotary software. This allows the XR20-W to be used even when it cannot be positioned directly on the rotary axis under test. Users can now test more machines and more different machine tools than was previously possible, explains the company.
Renishaw quotes one user as saying: "Before the XR20-W, our technicians relied on a combination of two devices: the old Renishaw RX10 and our in-house designed "Morleyometer" for applications where the calibrator could not be mounted on the centre of rotation. While these devices got the job done, they were heavy, cumbersome and slow. Set-up could be challenging, and the associated cables and fixturing meant that great care had to be taken to ensure that the test proceeded smoothly. With the wireless XR20-W set-up is now quick and easy.
The XR20-W can be used in 'off centre' applications such as trunnions and head type 5-axis machines. Thanks to the optional off axis rotary software, mechanical set-ups can be done quickly with just a simple generic mounting fixture, allowing the fully automatic test routine to proceed without delay.
The XR20-W is a totally wireless accessory for use with Renishaw's XL-80 and ML10 laser measurement systems. Together, they enable the automatic measurement of rotary axis positioning performance, with traceable ±1 arc sec accuracy.
