The increasing demand for automated devices in metalworking industries has driven significant advancements in lathe manufacturing. Conventional lathe operations, involving manual loading of copper and brass raw materials across three separate machines for taper turning, facing, and parting-off, have been observed to be inefficient. These manual processes result in excessive production time, increased labor costs, high raw material consumption due to human errors, and suboptimal product quality, thereby negatively impacting production capacity and overall cost-effectiveness. This study proposes an automated solution that integrates these three machining operations into a single automated mini lathe, enhancing efficiency without requiring a complete structural overhaul of traditional lathe machines. The implementation of automation has demonstrated a substantial improvement in productivity, increasing production capacity from 50 to 125 soldering iron bits per hour while optimizing space, time, and resource utilization. The results indicate that automation in lathe industries can significantly enhance manufacturing efficiency, reduce operational costs, and improve product quality.
