Laser System Provides Enhanced Parallelism Measurement Accuracy For Machine Tool Builders

Renishaw is releasing a new version of software for its XK10 alignment laser system at the upcoming EMO Milano 2021 which allows point-to-point parallelism measurements to be performed. This new functionality will enable users to make precise adjustments to machine parallelism to a level that has previously been impossible using traditional measurement techniques.

The XK10 alignment laser system provides a fast, precise, and efficient measurement tool for straightness, squareness, rotational parallelism, rail parallelism, flatness, and level, as well as assessing spindle direction and coaxiality of rotary machines. It is a powerful tool for diagnosing the source of errors following a rebuild or as part of regular maintenance.

The traditional method for parallelism measurement has previously been achieved by using a bridge plate and master rail, in combination with a dial gauge and level meter. This method is time-consuming and is prone to error as the measurements are recorded manually. The XK10 uses laser measurements to capture two points on each rail, allowing the angle between the two rails to be determined and recorded digitally.

Andy Deacon, Calibration Product Manager at Renishaw explained: “This latest release of software enables the XK10 to take measurements at multiple points along each rail. The benefit of an increased number of measurement points is that the straightness of each rail is also measured at the same time. Parallelism between the rails can then be determined by looking at the difference in straightness at each point, giving a more accurate picture than a measurement of the overall angle between rails.”

He continued: “The XK10 is supplied with fixturing solutions to reduce set up time and can be used with the optional parallelism optic designed specifically for this application. Making measurements where no rails are present is significantly improved using the included magnetic reference mount to easily slide the detector along the edge of a casting.”

Renishaw’s calibration products allow users to gain a greater understanding of a machine’s capability. Regular maintenance checks of the condition of a machine, with powerful diagnosis of the source of any errors, minimises reactive maintenance effort and focus on valuable preventative work. CARTO software suite provides data capture, analysis and compensation applications, simplifying the process for monitoring and improving position performance.
