The FLZ alignment tester is a transportable microscope for the alignment of machine guides.

Set-up of the measuring instrument

The measuring wire is fastened to the headstock or a special holding device, fed at the end of the base over a pulley and streched tight with a weight (layout according to DIN 8606).

The alignment tester must be placed on the carriage of the machine or a corresponding device, which can be moved in a longitudinal direction in predefined steps on the machine base. The measuring wire must be aligned in such a way that the same values are measured in the starting and end position of the carriage, i.e. that it is tensioned to form an imaginary connecting line parallel to these positions.

Technical description

The microscope and the stａnd are connected by a dovetail guide. To bring the measuring wire into focus the microscope can be vertically adjusted by means of a pinion gear on the stand. Horizontally, the position of the microscope is recorded by a digital measuring system and indicated in a LCD display. Since horizontal movement is effected in the object plane, errors of the first order are ruled out. With a spirit level the alignment tester can be precisely installed in a horizontal position. The microscope, spirit level and plane mounting surface, which is provided with two drilled holes for the insertion of the fastening bolts, are aligned to each other.
