What are the methods about CNC parts machining to remove rust?

General iron products will have rust, this is basic common sense, many people are aware of, then CNC parts processing or accessories when bearings and so on due to inventory conditions or improper rust will be such as prone to rust, and basically not be able to use mechanical methods to deal with, is the use of chemical pickling will damage the accuracy of the parts, then what methods can remove rust? The following I give you a summary of my experience to the method.

No damage to the workpiece, no change in the part, no corrosion. High precision parts rework or repair. Due to improper inventory or transportation caused by the surface of the parts generated floating rust, the use of Colin-306 can be very perfect to remove the floating rust, and to ensure the original precision.

I. Soaking cleaning process.

1 the professional cleaning solution into the tank (plastic or stainless steel tank is recommended, so as to reduce the penetration of iron ions into the original solution to reduce the service life).

2 with an electric heater heated to 40-50 degrees and maintain, room temperature can also be just need to extend the time.

3 the hardware processing parts immersed in the tank.

Second, wipe cleaning process.

1 repeatedly wipe with a rag Bun, this approach is suitable for large equipment or workpiece cleaning and rust removal.

2 after wiping, blow dry with hot air or natural drying can be coated with anti-rust oil.
