Common Problems of Aluminum Alloy Processing

With the demand for lightweight in many markets, aluminum alloy processed products have become the first choice of more and more component manufacturers, and the processing of aluminum alloy processed products has also attracted much attention. Aluminum alloy is a general term for alloys formed by adding alloying elements to pure aluminum. The main alloying elements are copper, silicon, magnesium, manganese, etc. The advantages of aluminum alloy in terms of density, tensile strength, elongation, corrosion resistance, etc. make it the most widely used non-ferrous metal material in the industry, formed by aluminum alloy processing. Products play an important role in aviation, aerospace, automobile, machinery manufacturing and other industries.

Compared with ferrous metal processing, aluminum alloy processing has its special processing performance. In the process of aluminum alloy processing, problems such as sticking knife, tapping and broken teeth, and non-machined surface mold are prone to occur.


  1. Broken teeth, sticking knife, unqualified surface finish when tapping

Aluminum alloy has soft properties and low melting point, so problems such as broken teeth and sticking of knives are prone to occur during aluminum alloy processing. In addition to changing the processing parameters, such as avoiding medium-speed cutting and easy-to-stick knives, cutting fluids with good lubricity and cooling performance should also be used.

  1. Mildew on the unfinished surface

Most problems in aluminum alloy machining are caused by cutting fluids. The lack of cutting fluid product design means inevitable problems in the processing process. When mildew occurs, the corrosion inhibition ability of the cutting fluid and the storage method after processing should be improved.

  1. Residues on the machined surface affect post-cleaning

Generally, aluminum alloys need to be cleaned after processing. If the cleaning ability of the aluminum alloy cutting fluid is not good, there will be residues on the surface of the aluminum alloy machining, which will affect the appearance or post-coding treatment. Usually related to the emulsification system design and cleaning process of cutting fluid products.
