CNC Machining: What is the Wire Drawing Surface Treatment Process of CNC Machining Parts?

Normally, the finished CNC machined parts need some surface treatment processes, which can make the appearance of the CNC machined parts more beautiful and generous. Among them, wire drawing is a kind of surface processing technology in the CNC machined parts. This type of CNC machining technology is used in aluminum. There are many alloy CNC machined parts, which can enhance the color of CNC machined parts a lot. How much do you know about the drawing process of the surface layer of the CNC machined parts?

The surface drawing process of CNC machining parts can be made into random patterns, straight patterns, corrugated patterns, thread patterns, and spiral patterns according to the needs of decoration. The chaotic pattern is a kind of irregular and non-obviously textured matte silk pattern obtained by moving the CNC machined parts up and down and left and right under the high-speed copper wire brush. This kind of CNC machining has higher requirements for the surface layer of aluminum or aluminum alloy prototypes.
 

What are the drawing processes?

1. Wire drawing is a repairing process, and it can also play a beautiful role. Because there are local scratches on the surface of the metal CNC machined parts, use a wire drawing machine to make consistent scratches on the entire surface to reduce the wall thickness to cover the local scratches. It is good not to have work hardening after CNC machining, which will change the performance, but scratches are not easy to avoid, so they are often used. Wire drawing not only removes scratches on the surface of CNC machined parts, but also has the dual effect of beautifying and decorating the surface of CNC machined parts.

2. Straight-grain straight-grain wire drawing refers to the machining of straight lines on the surface of CNC machined parts by mechanical friction. It has the dual functions of removing scratches on the surface of the aluminum plate and decorating the surface of CNC machined parts.

3. The chaotic pattern is a kind of irregular and non-obvious matt silk pattern obtained by moving and rubbing the CNC machined parts back and forth under the high-speed copper wire brush. This kind of CNC machining has higher requirements for the surface layer of aluminum or aluminum alloy prototypes.

4. Swirl Swirl, also known as optical rotation, is a kind of silk pattern obtained by using cylindrical felt or grind nylon wheel to install on a drilling machine, blending polishing paste with kerosene, and rotating and polishing the surface of CNC machined parts. It is mostly used for decorative CNC machining of round signs and small decorative dials.

5. Corrugations are generally made on brushing machines or rubbing machines. Using the axial movement of the upper group of grinding rollers, the surface of the aluminum or aluminum alloy CNC machined parts is brushed to obtain wave patterns.
