What are the rust removal methods for CNC precision parts processing
CNC precision parts processing or parts when bearing, etc. will cause embrittlement due to improper storage conditions or rust prevention, which can hardly be treated mechanically, while chemical pickling will damage the precision of parts. On the basis of years of processing experience, Haishuoda Technology has summarized some rust removal methods, which will not damage the workpiece, change the parts or be corroded. Rework or repair high-precision parts. Due to improper storage or transportation during processing of CNC precision parts, floating rust is generated on the surface of parts. Corin-306 can perfectly remove floating rust and ensure the original accuracy;
1、 Soak cleaning process
1 CNC precision parts processing adds professional cleaning solution to the tank (it is better to use plastic or stainless steel tank to reduce the iron ion penetration into the solution and reduce the service life);
2 Use an electric heater to heat to 40-50 ℃ and keep it at normal temperature, which can only be extended;
3 Immerse the hardware processing parts into the tank;
4 If the efficiency needs to be further improved, the circulating pump can be added to stir the tank liquid;
5 Take out the workpiece after all the rust is dissolved, and rinse it with water-based rust inhibitor;

6 Natural drying or drying after rinsing, or direct dehydration and rust prevention;
7 If necessary, conduct comprehensive rust prevention and transfer to the next process.
2、 Wiping and cleaning process
1. Wipe repeatedly with a rag, which is suitable for cleaning and derusting large equipment or workpieces;
2 After wiping, dry it with hot air or natural drying, and then apply anti rust oil.
