When too many shims are placed under a machine foot, it can create an unsteady support structure for the machine. This improper support can lead to the machine rocking or swaying during operation. The rocking can result in unnecessary vibrations, which can negatively impact the performance and longevity of the equipment, leading to misalignment, increased wear, and potential damage.

In contrast, having an optimal number of shims is crucial for achieving the correct level and stability needed for proper machine operation. This helps ensure that the machine stays in its intended position, reducing the risk of operational issues arising from instability. Proper alignment and support also play a significant role in maintaining machinery performance and preventing failures. Therefore, managing the number of shims effectively is paramount to preserve machine integrity and operational efficiency.
