Following installation, check the functioning and accuracy of the guideway as follows:
Parallelism
Check compliance with parallelism tolerances using a dial gauge and two coupled
carriages.
Use the vertical lateral locating surface on the parallel rail as a reference surface.
Special adapter plates are available for checking AMS guideways.
Running Accuracy
Check running accuracy using a laser, autocollimator, or dial gauge. In order to obtain
correct results, measurements should always be made at the machine slideway and
not at individual carriages.
Vertical running measurement with two measurement sensors
Two measurement sensors are recommended in order to identify angle deviations
of the carriage along the longitudinal rail axis by differential measurement. Ensure
when using a measurement sensor in lateral position that this is as close as possible
to the guide rail.
Horizontal running measurement with two measurement probes
Two measurement sensors are recommended in order to identify angle deviations
of the carriage along the longitudinal rail axis by differential measurement. Ensure
when using a measurement probe in deep position that this is as close as possible
to the centre of the guide rail.
