What are the methods for removing rust from CNC precision parts?

Precision parts processing or accessories When the bearing or the like is damaged due to improper inventory conditions or rust prevention, it cannot be treated mechanically, and chemical pickling will damage the accuracy of the parts. Based on years of processing experience, Haishuoda Technology has summarized some methods of derusting, no damage to the workpiece, no change in parts, and no corrosion. High-precision parts rework or repair. The use of Colleen-306 can perfectly remove the rust due to improper storage or transportation, and ensure the original accuracy;

First, the soaking cleaning process

1 Add the professional cleaning solution to the tank (preferably plastic or stainless steel tank, which can reduce the penetration of iron ions into the stock solution to reduce the service life);

2 Heat up to 40-50 degrees with an electric heater and keep it at room temperature.

3 soak the metal processing parts into the slot;

4 If it is necessary to further improve the efficiency, increase the circulation pump to stir the bath;

5 After the rust is completely dissolved, the workpiece is taken out and rinsed with a water-based rust inhibitor;

6 Rinse or dry naturally after rinsing, or directly dehydrate and rust;

7 When necessary, perform full rust prevention and transfer to the next process.

Second, the wiping cleaning process

1 Wipe repeatedly with a rag, this method is suitable for cleaning and rusting of large equipment or workpieces;

2 After wiping, apply anti-rust oil after drying with hot air or drying naturally.
