Automatic Oiler is an immersion-type oiling system designed for efficient automatic oiling and rust prevention of flat workpieces such as friction plates, valve plates, and steel back flange plates. After immersion oiling, excess grease is precisely removed by oil-squeezing rollers, forming a uniform oil film without oil droplets. Compared with traditional oiling machines, it effectively eliminates oil mist pollution and oil waste, significantly improving energy efficiency and reducing oil consumption. The system supports customization based on specific product processes and is ideal for clean, environmentally friendly, and stable automated production lines.
