What's the Electrophoresis?

The process involves immersing the machined part into a bath containing a dispersion of electrically charged particles, typically paint or pigment particles. An electric field is then applied, causing the charged particles to migrate and deposit onto the surface of the part. The deposited particles adhere to the surface, forming a uniform and durable coating. Electrophoretic deposition offers several advantages. It provides excellent coating uniformity, even on complex-shaped parts, due to the electric field evenly distributing the particles across the surface. The process can also be used to enhance the corrosion resistance, improve the aesthetics, or provide specific functional properties to the CNC machined part. By selecting suitable coating materials and adjusting the process parameters, such as voltage and deposition time, the desired coating thickness and properties can be achieved. This makes electrophoretic deposition a versatile and controllable technique for post-processing CNC machined metal parts.

What's the galvanization?

Galvanization is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of molten hot zinc.

What's the Powder Coating?

Powder coating is a dry finishing process used to apply a protective and decorative coating to various surfaces. This is a process where powdered paint is sprayed onto a part that is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic.

Sprying Painting

After CNC machining, the parts may have rough surfaces, visible tool marks, or inconsistencies in color or texture. Spray painting can be used to address these issues and enhance the appearance of the parts. The process typically involves the following steps: Surface Preparation: The machined parts need to be properly cleaned and prepared before painting. This may involve removing any oils, debris, or machining residues from the surface. Surface cleaning techniques such as solvent cleaning or sandblasting may be employed to ensure good paint adhesion. Priming: Applying a primer coat is often the first step in the spray painting process. The primer helps to create a smooth and uniform surface, improves paint adhesion, and enhances the durability of the final paint layer. It also helps to seal any small imperfections on the surface. Painting: Once the primer coat is applied and dried, the actual paint is sprayed onto the parts. The choice of paint can vary depending on the desired appearance, durability requirements, and the type of material being painted. Different types of spray guns or aerosol cans can be used to achieve the desired effect, whether it's a solid color, metallic finish, or other special effects. Clear Coating (Optional): In some cases, a clear coat may be applied on top of the paint to provide additional protection, gloss, or desired finish. The clear coat helps to seal and protect the painted surface from environmental factors such as UV radiation, moisture, and abrasion. Drying and Curing: After the painting process is complete, the parts need to be allowed to dry and cure. The drying time can vary depending on the type of paint and environmental conditions. By spray painting CNC machined parts, manufacturers can achieve desired aesthetics, improve surface quality, and provide additional protection against corrosion or wear. It allows for customization, color coding, branding, or simply enhancing the overall visual appeal of the parts.

What's the black oxide?

Black oxide is a treatment used to enhance corrosion resistance and reduce light reflection. It's often used for alloy steel, mild steel, tool steel, and stainless steel.

What's the Bead Blasting?

After bead blasting, it can remove the machining marks. The part surface is left with a smooth, matte appearance.

What's the Anodized？

Anodizing creates a corrosion-resistant finish and allows parts to be anodized in various colors such as clear, black, red, and gold, with black being the most common. It is typically associated with aluminum. (Note: 1. There may be a slight color variation between the actual color after anodizing and the colors mentioned above. 2. Rack marks are a natural outcome of the anodizing process. When designing a part for anodizing, it is important to identify where the part will be racked. The racking location is usually chosen to minimize the visibility of the mark after assembly.)

How Does CNC Milling Work?

Use a multi-point rotating tool to remove material from the workpiece. Start by fixing a block of metal or plastic material inside the CNC mill. Using G-code, the CNC machine is programmed to rapidly mill out parts from the block of raw material. Basic mills consist of a 3-axis system (X, Y, and Z), which is still one of the most popular and widely used machining processes. In 3-axis machining, the workpiece remains fixed, and the rotating tool cuts along the x, y, and z axes. 4-axis CNC machining and 5-axis CNC machining have higher versatility and are often used in the production of high-precision parts.
