Essential Checklist for Laser Alignment & Soft Foot Prevention

Before initiating laser alignment, verify several critical factors to prevent later complications and guarantee optimal outcomes.

Consider the following essentials.

Foundation: A solid, rigid base is the cornerstone of successful alignment.

Machine mobility: Position both machines with roughly 80 mils of shims beneath each foot in case one unit must be lowered. Jacking bolts offer a safer and more precise method for horizontal adjustments.

Rigid couplings: Loosen couplings to obtain accurate measurements.

Coupling play: Minimize play by rotating the shafts a few degrees before measurements and taking all readings in the same direction.

Bearing play: Inspect for excessive bearing play.

Soft foot: Detect soft foot conditions, which can dramatically shorten a machine’s service life.

Here are straightforward measures to eliminate soft foot.

1. Remove rust, dirt, and any other contaminants from machine foot contact surfaces, shims, and the frame or foundation.
2. Never place more than four shims under a single foot; using more than three can create a spring effect.
3. Eliminate external forces on the machine, such as those from connected piping, conduit, or auxiliary supports.
4. Use high‑quality, clean, and uniform shims when shimming is necessary.
