What should be done when installing new equipment to be cross dial aligned?

When installing new equipment to be cross dial aligned, proper alignment techniques are critical to ensure the efficient and reliable operation of machinery. The process involves using dial indicators to measure the alignment between the new equipment and the fixed machine.

Having the dials clamped onto the shaft of the new equipment while reading off the fixed machine allows for accurate measurement of any misalignment. The gauges will indicate how much the new equipment is out of alignment in relation to the fixed machine, providing the millwright with the necessary data to make adjustments and align the machinery properly.

For cross dial alignment, it is important to take measurements while ensuring that the dials are positioned accurately, which includes the possibility of having the dials positioned either higher or lower than the fixed machine. This versatility in positioning allows for capturing the true alignment conditions of the shafts, so recognizing that both the higher and lower positions can yield valid readings is crucial to the alignment process.

Therefore, the correct approach involves both clamping the dials on the shaft to read from the fixed machine and recognizing that the dials may be either above or below the fixed machine. This comprehensive understanding ensures that the alignment process is conducted effectively, thus leading to optimal machine performance after installation.
