What are the rust removal methods for CNC precision parts?

The embroidery corrosion of precision parts or accessories such as bearings can not be treated by mechanical method due to improper storage conditions or rust prevention, while the precision of parts can be damaged by chemical pickling. Based on many years of processing experience, some rust removal methods are summarized, which do not damage the workpiece, parts will not change, and will not be corroded. High precision parts rework or repair. Due to improper storage or transportation, floating rust on the surface of parts can be completely removed by using Colin-306, and the original accuracy can be ensured. First, soaking cleaning process 1, adding professional cleaning liquid into the tank (plastic or stainless steel tank, which can reduce the service life of iron ion infiltration into the original solution); second, heating to 40-50 degrees with electric heater and maintaining. At room temperature, it can only take longer time; 3. Soak the hardware parts into the tank; 4. If need to further improve the efficiency, increase the circulating pump to stir the tank liquid; 5. Remove the workpiece after all the rust is dissolved and rinse it with water-based antirust agent; 6. Dry or dry it naturally after rinsing, or dehydrate it directly to prevent rust; 7. When needed, do it. All-round rust prevention and transfer to the next process. 2. Wipe cleaning process 1. Repeatedly wipe with a cloth, this method is suitable for cleaning and rust removal of large equipment or workpieces; 2. After wiping, apply rust-proof oil after hot air drying or natural drying.
