Aluminum alloy castings are made by filling the mold with molten metal to obtain aluminum alloy blanks of various shapes. It has the advantages of low density, high specific strength, good corrosion resistance and casting processability, and is less limited by the structural design of the parts.

Precision machining of mechanical parts is a type of machining, but it is precision machining. With the development of industry and the continuous changes in demand, precision machining has undergone many changes.
