1. Detailed introduction to processing methods

CNC machining is a digitally controlled precision machining technology that controls the movement and operation of machine tools through computer programs, and can achieve high-precision, complex-shaped parts machining. For example, in the aerospace field, CNC machining is often used to manufacture engine blades, precision structural parts, etc.

3D PRINT metal printing is an additive manufacturing technology that builds parts by stacking metal materials layer by layer. It can produce complex geometric shapes that are difficult to achieve with traditional machining, such as parts with complex internal channels. For example, in the medical field, personalized orthopedic implants can be printed.

Punch stamping uses the impact force of the punch to deform the sheet in the mold to obtain parts of the desired shape and size. It is often used for mass production of simple-shaped metal parts, such as metal shells in automotive parts.

2. The role and application of surface treatment

Oxidation treatment can form an oxide film on the metal surface to enhance the corrosion resistance and wear resistance of the metal. For example, after oxidation treatment, the surface of aluminum products is harder and less prone to scratches, and is often used in door and window frames.

Electroplating can coat a layer of other metals on the metal surface to improve the appearance, corrosion resistance and conductivity. For example, in electronic products, many metal parts are electroplated with gold to improve conductivity and oxidation resistance.

Spray painting can provide rich colors and decorative effects for metal surfaces, and can also play a certain protective role. In the furniture industry, metal parts are often sprayed with paint to achieve the purpose of beauty and rust prevention.

3. Characteristics of processing of different metal materials

Aluminum plate processing has the advantages of light weight, high strength and good corrosion resistance. It is often used in aerospace, automobile manufacturing, electronic equipment and other fields, such as aircraft skins, automobile wheels, electronic product housings, etc.

Iron processing has relatively low cost and high strength, but it is easy to rust. It is commonly used in building structures, mechanical parts, such as steel beams, gears, etc.

Stainless steel processing is widely used in kitchen utensils, medical equipment, chemical equipment and other fields due to its excellent corrosion resistance and aesthetics, such as stainless steel sinks, surgical instruments, chemical pipelines, etc.
