Do you know why aluminum CNC needs to be cleaned after processing

The main reason why aluminum CNC needs to be cleaned after processing is to remove residual oil stains, metal chips and other impurities during processing to ensure the smoothness and overall performance of the surface of the aluminum part. Here are some answers to related questions:

1. Do aluminum parts need to be cleaned before processing?

Generally speaking, aluminum parts need to be cleaned before processing to ensure that the surface of the parts is clean and dust-free, and avoid contamination of cutting fluids and other substances during the processing.

2. How to choose the appropriate cleaning agent?

The selection of cleaning agents should be based on the material and surface treatment requirements of aluminum parts. Generally, weakly alkaline or neutral cleaning agents are selected, such as sodium alkylbenzenesulfonate and other cleaning agents. For aluminum parts with special requirements, organic solvents or halogenated alkyl solvents can also be used for cleaning, but these solvents have high toxicity and volatile properties and need to be used safely.

3. What are the cleaning methods?

Commonly used cleaning methods include soaking method, spraying method and ultrasonic cleaning method. Among them, the spray method and ultrasonic cleaning method have better cleaning effects and energy-saving and environmentally friendly advantages. It is necessary to choose the appropriate cleaning method according to the specific situation.

4. How to check the surface quality of aluminum parts after processing?

Examination can be performed by visual inspection, hand touch or using a microscope. It should be noted that for some high-precision aluminum parts, it may be necessary to use optical measurement or three-coordinate measurement to accurately measure.

5. Does it need to be dried after cleaning?

The cleaned aluminum parts should be dried to avoid moisture residue affecting the quality and corrosion resistance of the part surface. It can be processed by natural drying or heating and drying.

To sum up, cleaning is an indispensable link after CNC processing of aluminum parts. Pay attention to the selection of cleaning agents, cleaning methods, cleaning parameters, and drying treatment. Only through scientific cleaning processes can the surface quality and service life of aluminum parts be guaranteed.
