When making parts out of sheet metal, Junying, it is necessary to perform surface treatment on the parts in the form of powder coating, electroplating, anodizing, and other similar processes. It is necessary to perform surface treatment in order to protect against the effects of rust and corrosion on some of the sheet metal materials because these materials do not have an anti-rust or anti-corrosion function. The product's outward appearance can also be improved through the application of surface treatment.

In order to fulfill the aforementioned requirements, the following surface treatment processes can be applied to sheet metal:

Galvanized can be defined as the process of using electrolysis to form a uniform, dense layer in the product surface that is combined with a good metal or alloy deposition.

The same principle applies to chrome plating as it does to galvanizing; however, the corrosion resistance of chromium coating is seven to ten times stronger than that of galvanized, and the surface is significantly more beautiful; however, the cost is higher.

• Powder coating refers to a process in which the powder is polarized and evenly attached to the surface of the product on the opposite side, which occurs as a result of the action of an electric field

• It is a part of the physical transformation

• The use of static powder coating does not contribute to the pollution of the atmosphere, the powder itself can be recycled to cut down on the expense of the materials, the coating is resistant to the corrosion caused by acids, alkalis, and salts, and it also has a higher level of adhesion

   

Plastic dip: plastic dip is a new type of technology for the process of treating metal surface corrosion, metal preheating, leaching, and curing. Plastic dip is used in all three of these steps. During the process of leaching, the heated metal adheres to the material; the length of time required for the process, as well as the thickness of the material, increases in proportion to the degree to which the metal was heated. The plastic coating has a deep color, is resistant to acids and alkalis, provides superior cold insulation, and has anti-corrosion properties.

Which Types of Processing Objects Are Typically Utilized in the CNC Milling Process?

CNC milling machines are not only able to process all of the different kinds of parts that are able to be processed by conventional milling machines, but they are also able to process more complex surface parts, which conventional milling machines are unable to process. Flat parts, variable angle parts, space surface contour parts, punching parts, threaded parts, and so on are some examples of common processing objects that are suitable for CNC milling machines because of the characteristics of the CNC milling machine.

The frame of the aircraft is made up of a variety of flat parts, including covers, cams, and the overall structure. The majority of the work that was done by the CNC milling machine on the objects CNC machining steel processed was on the flat parts.

Variable angle parts

The working surface and the horizontal angle of the continuous variation of the variable bevel parts are the two primary characteristics that define variable bevel parts in general. As an illustration, the utilization of the aircraft on the oblique angle beam is an example of a variable bevel part.

Space surface contour parts

A spatial surface is what you get when you machine this kind of part's surface. Mold, blades, propellers, and other similar components are examples of common space surface parts. When milling this kind of component, the milling cutter and the surface being machined are in constant point contact with one another.

The meat of the fight

CNC milling machines are used in the punch operation, which can be performed in a number of different ways. Such as drilling, expansion, hinge, and boring, as well as other types; however, because it needs to change drilling tools frequently, CNC milling machine drilling hole is not very convenient. Examples include: drilling, expansion, and boring.
