Straightforward laser alignment measurement
The XK10 laser alignment system from Renishaw assists machine tool builders and other engineers with enhanced parallelism measurement accuracy
P
recision measurement specialist Ren- ishaw is releasing a new version of soft- ware for its XK10 alignment laser
system. The new system enables point-to- point parallelism measurements to be per- formed and this new function will allow users to make precise adjustments to machine par- allelism to a level that has previously been im- possible using traditional measurement techniques. The XK10 alignment laser system provides a
fast, precise and efficient measurement tool for straightness, squareness, rotational par- allelism, rail parallelism, flatness and level, as well as assessing spindle direction and coax- iality of rotary machines. It is a powerful tool for diagnosing the source of errors following a rebuild or as part of regular maintenance.
Lasers replace dial gauges /// The traditional method for parallelism mea-
surement has previously been achieved by using a bridge plate and master rail, in com- bination 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 deter- mined and recorded digitally. According to Andy Deacon, calibration
product manager at Renishaw, the latest release of soft- ware enables the XK10 to take measurements at mul- tiple points along each rail. The benefit of an increased number of measurement points is that the straight- ness of each rail is also mea- sured at the same time. Parallelism between the rails can then be de- termined by looking at the difference in straightness at each point, giving a more ac- curate picture than a measurement of the overall angle between the rails. “The XK10 is supplied with fixturing com-

The XK10 provides high accuracy parallel straightness
measurements without the need for dial gauges and level meters, above; straightforward calibration can be performed using the
reference rail for making parallel straightness measurements, left; and the XK10 software provides a visual reference of rail run-out along with absolute readings for the user, inset
ponents 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,” he says. Renishaw’s calibration products, including the XL-80 laser interferometer, QC20-W ball-
bar and XM-60 multi-axis calibrator, are es- sential tools to gain a greater understanding of a machine’s capability. Regular mainte- nance 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. The CARTO software suite provides data capture, analysis and compensation applications, sim- plifying the process for monitoring and im- proving position performance. THDx
