Several points should be checked prior to laser alignment in order to avoid problems later and to achieve good results.
Keep the following in mind.
Foundation: A solid, rigid foundation is essential for a successful alignment.
Machine mobility: It is advisable to set both machines with about 80 mils of shims underneath the feet in case one machine needs to be lowered. Also, jacking bolts provide a safer and more accurate way to make horizontal moves.
Rigid couplings: These must be loosened to achieve accurate readings.
Coupling play: This can be avoided by turning the shafts a few degrees before starting measurements and then taking readings in the same direction.
Bearing play: Check for excessive bearing play.
Soft foot: Check for soft foot.
Soft foot can severely affect the operating condition of a machine, which will undoubtedly shorten its life expectancy. Here are a few simple tips to help avoid soft foot in your machines.
