We know that residual fingerprints on the smart lock panel is a rather troublesome problem. First, it will make the panel dirty and needs to be cleaned regularly. Second, it will always make people feel unsafe to expose their fingerprints to the outside. So what kind of black technology is the “CNC process” here? How does it solve this problem?
CNC Process
The full name of CNC is Computer Numerical Control, also known as “Numerical Control”. The CNC process is a process of processing the product structure and shape through numerical control equipment.
Initial Application
In line with the original intention of producing fine parts, CNC technology came into being. It is an all-metal unibody process pioneered by Apple. After precision machining, the aluminum plate is first cut to form the prototype of the integrated fuselage. As the fuselage gradually takes shape, the shape of the keyboard and various fine structures on the fuselage are milled out. In the past, metal casting mainly used the die-casting process. Generally speaking, the mold was made in advance, and then the molten metal was poured into the mold, and the product was obtained after cooling. The advantage of this process is that it is suitable for mass production, but the disadvantage is that it is not fine enough. Therefore, the CNC process can be vividly understood as “carving”, and the CNC milling machine is equivalent to a “cutting knife”, and the whole piece of aluminum is “carved” into shape.
Advantages of CNC
1. Since the CNC process is “carved” from a whole piece of metal, the strength is more guaranteed. The CNC-made panels are guaranteed not to break even under heavy external pressure.
2. Since it does not involve cooling of molten metal, there are no pores on the surface, which is relatively smooth, which is more conducive to the surface treatment process.
3. The surface treatment process of the CNC process is anodic oxidation. A layer of aluminum oxide film is formed on the surface of the panel through the principle of electrolysis, which can effectively improve the surface hardness of the aluminum material.
4. For the panel of the smart lock, the combination of CNC process and anodizing process can improve the hardness of the panel and make the panel smoother, thereby reducing the residue of fingerprints.
5. The surface processed by CNC can have various color effects, and can also realize the three-dimensional effect on the product, so that the texture of the metal itself can be improved.
6. CNC is easy to modify the size parameters through programming
After reading this article, we believe that you have a deeper understanding of CNC technology. For consumers, they can make reasonable choices based on the actual effect of CNC technology and their own economic conditions.
The intelligent anti-theft lock adopts CNC engraving process and sandblasting oxidation process, which is wear-resistant and anti-oxidation, scratch-resistant and corrosion-resistant, and is not afraid of moisture, so that the intelligent lock will last forever!
