Sample of a Mill Alignment Report
Optical alignment methods are slow, less accurate and only tell you what's wrong. Geometry lasers are easier to set up, simpler to use and provides the information to actually fix alignment problems. Laser position measurement readout is digital with no interpolation. Only one operator is required to do setup and measurement collection. The readings obtained from the laser digital display shows how the machine is out of alignment and also what modification is needed to bring the equipment into perfectly alignment.
For example, when aligning roll forming or welded tube forming shafts, the laser digital display shows the exact offsetdimension between the rollshaft shoulders and the machine reference keyway. The report generated from the measurements specifies the dimensions for new permanent spacers or provides the instruction for shim relocation in the bearing housing. After new master spacers are installed or shims relocated, the roll shaft shoulder locations are checked a final time to confirm that the adjustments are correct. With laser target readout accuracy of +/- 0.001” the achievable accuracy of a laser alignment far exceeds what is possible with any optical system (or a piano wire!)
Laser alignment advantages
Proper rollshaft alignment is directly related to roll tool wear life, setup time (prime to prime change over)and end product quality. There is a direct correlation between these variables.
Properly aligned equipment decreases downtime, insures the highest quality product,and in the end, imparts longer life to roll tooling, rollshafts, bearings, drive components, etc.
The savings on roll tool regrinds alone, justifies the cost of an alignment.
