For the barrel polishing machine, add 0.5 kg of compound and 10% abrasive media. Barrel Polishing Procedure:
1. Workpieces requiring polishing must first undergo degreasing, rust removal, and descaling treatments; this step is unnecessary if the workpieces are free of oil, rust, and scale.
2. Place the workpieces to be polished into the barrel polishing machine. For every 100 kg of workpieces, add 2 to 5 kg of polishing liquid, 2 to 5 kg of water, and 10% abrasive media.
3. The processing time ranges from 30 to 70 minutes; afterward, simply remove the workpieces and rinse them thoroughly with water.
