Alignment Tester FLZ

The setup: The measuring wire gets attached at both ends of the machine bed in the axis of the measuring microscope. On one side this is carried out individually while on the second side there is a special holder, where a wire is guided over a roller and tensioned with a weight (arrangement according to DIN ISO 8606 as well as DIN ISO 230-1.

The alignment tester FLZ is placed either on the carriage of the machine or on a corresponding measuring base. With height and lateral adjustment, the measuring wire gets placed in focus. Now, the measuring wire has to get aligned in a way that the same values will be displayed at the start and end position of the carriage – that is, as parallel as possible to the traverse axis. The adjusting of the wire over the wire holder is done with the roll, which can be fine-tuned in two directions.

In the relative measuring position, the microscope is matched with the wire. For this, the adjustment is performed with a fine adjustment screw until the two images overlap in the sectional eyepiece. The measurement is now done either directly by reading or by sending the measured values wirelessly to the computer.

With corresponding software programs, these individual values are then displayed as straightness. The measurement can be evaluated according to ISO, regression or endpoint.
