CORRECTIVE MAINTENANCE PADA MESIN FRAIS AJAX FR 15

Abstract

Milling machines play a crucial role in manufacturing processes, including in vocational education environments such as the State Manufacturing Polytechnic of Bangka Belitung. Over time and with frequent use, the Ajax FR 15 milling machine has begun to show signs of wear and malfunction, affecting its overall performance. This final project aims to identify the types of damage occurring on the machine, analyze their root causes, and carry out corrective maintenance actions to restore its functionality. Data collection was conducted through direct observation, interviews with technicians, and documentation of the machine's condition. The analysis revealed that the main issues were found in the spindle and worktable components, primarily caused by wear and a lack of regular maintenance. The corrective actions involved replacing damaged parts and readjusting critical components. Following the repair process, the machine was able to operate optimally and was ready to be used again for practical learning activities. The results of this project are expected to serve as a reference for better implementation of machine maintenance in the future.
