Renishaw’s XR20-W rotary-axis calibrator helps users to test a wider range of machines in less time. The addition of off-axis rotary software allows the unit to be used even when it cannot be positioned directly on the rotary axis under test.

The XR20-W is a wireless accessory designed 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-second accuracy.

Application benefits

  • Tony Morley, president at Morley Machine Alignment, said the XR20-W rotary-axis calibrator has transformed the way the company calibrates rotary axes on its machine tools. Setup is quick and easy, he added. The XR20-W can even be used in ‘off-centre’ applications such as trunnions and head-type five-axis machines. Morley said the unit is one of the tools that has enabled the company to offer high-end aerospace component manufacturers a very high standard of service.
  • Satheesh Jayanna, assistant manager of quality assurance at Starrag India, said the XR20-W rotary-axis calibrator with Bluetooth has improved the company’s productivity and working safety, while the simplified alignment methods and user-friendly software have boosted flexibility.
  • C S Venkatesh, deputy general manager of machine building, quality and service within the machining solutions group at Kennametal India, said using the XR20-W has increased the machine calibration accuracy and the confidence level of staff. It is also saving significant time compared with alternative methods.
  • Luke Wang, assistant general manager of the quality control department at Hurco, said the easy and flexible setup, size, weight, wireless operation and user-friendly software of the XR20-W has allowed the company to reduce setup times by 40 per cent and test time by 20 per cent. Bluetooth has allowed for safer testing.
  • V Saravanan, manager of quality assurance within the machine tool division at Lakshmi Machine Works, said the XR20-W is compact and easy to align and allows the company to calibrate any angle with accuracy. It has reduced calibration time by 50 per cent.
