Building on the foundation laid in the machine assembly and installation training, this course dives into the nuanced skill of identifying and controlling component failure. We've found that many machinery problems experienced on a daily basis are unrelated to issues of precise alignment or balance. This calls for a craft-centric, analytical approach towards understanding these problems and their potential solutions. This session aims to enrich craftsmen with a holistic understanding of how machinery components like bearings, lubrication systems, couplings, and seals operate, fail, and can be maintained. Through a blend of theoretical knowledge and hands-on exercises, attendees are prepared to tackle real-world challenges in their work environments.
