What is a primary advantage of using pre-cut shims over job-made shims?

The primary advantage of using pre-cut shims is that they are available in standard thicknesses. This standardization allows for quick and precise adjustments during millwright alignment tasks, making the process more efficient. When using pre-cut shims, a technician can easily select the appropriate thickness to achieve the desired alignment without the need for additional cutting or shaping, which is often required with job-made shims. This feature not only speeds up the alignment process but also ensures greater consistency and reliability in the adjustments being made. Standard thickness measurements help eliminate guesswork and promote a more structured approach to aligning machinery, improving overall performance and accuracy in maintenance tasks.
