During the initial phase of a new machine's operation, several factors contribute to increased wear and potential issues. First, the parts are not yet fully broken in. Due to manufacturing, assembly, and adjustment processes, the surfaces of these components are often rough, with limited contact area between mating parts. This uneven contact leads to localized high-pressure points. As the machine runs, the irregularities on the surfaces interact, causing metal particles to break off and act as abrasives, further accelerating wear. This is especially true for critical mating surfaces, which can suffer significant damage if overloaded during this period. If not handled carefully, early mechanical failures may occur.
Second, lubrication is often inadequate during the break-in phase. The small clearance between newly assembled parts makes it difficult for lubricants to form a consistent oil film across the friction surfaces. Without proper lubrication, the resistance between moving parts increases, leading to abnormal wear. In extreme cases, this can cause scoring or even seizing of precision-matched surfaces, resulting in serious mechanical failure.
Third, geometric deviations and dimensional inaccuracies are common in newly manufactured and assembled parts. These imperfections, combined with the effects of impact, vibration, temperature changes, and excessive wear, can cause fastened components to loosen over time. This can lead to misalignment and further mechanical issues.
Fourth, leakage is a frequent problem during the run-in period. Mechanical vibrations, heat, and stress can cause seals and pipe joints to loosen or fail. Additionally, some defects from casting or machining—such as cracks or poor surface finishes—may not be evident during assembly but become apparent under operational conditions. This results in oil or water seepage, making leakage a common issue during the early stages of use.
Finally, human error is more likely during this time. New operators may not be fully familiar with the machine’s structure and performance, increasing the risk of improper operation. This can lead to malfunctions, and in worst-case scenarios, even mechanical accidents. It’s essential to provide proper training and guidance during the initial operation phase to minimize such risks.
