This video demonstrates the precision polishing process of cable connectors. Skilled workers operate CNC polishing equipment to process metal connector surfaces. Automated polishing heads operate at precise speeds and pressures for multi-angle grinding, removing micro imperfections. Operators use magnifiers to inspect polishing results in real-time, ensuring mirror-like finish on every contact surface. The polished connectors undergo conductivity and wear resistance tests to guarantee signal transmission stability. These high-precision connectors will be used in medical equipment and communication systems, reflecting modern manufacturing's utmost attention to detail quality.
