Once the technicians have understood the kind and extent of the misalignment, which can be of the type “angular” or “parallel” type, they will insert calibrated shims under each support bearing foot of the mobile machinery part (usually the motor).
This will ensure precise positioning with errors of up to a few hundredths of a millimetre.
In the case of alignment of machines subject to significant temperature variations, the technician will also provide the so-called “thermal compensation” of the expansion.
The maximum misalignment tolerated is suggested by tables commonly found in the literature, instrument manufacturers, and rotating machines.
We position the laser heads on each shaft so that they can “look at each other”.
We insert the main dimensions of the machinery to be aligned
We correct the “soft foot” before performing the actual alignment
We rotate the shafts to determine the misalignment and necessary corrections
We apply shims to correct the misalignment detected
We recheck after the intervention has taken place, detecting the “before” and “after”.
