The reasons why CNC precision processing is not usually chosen for processing mobile phone casings are as follows:
High cost: CNC precision machining equipment and technology are relatively complex and require high investment costs. For the mass production of mobile phone casings, the use of CNC precision machining methods may lead to excessive costs and uncompetitiveness.
Low processing efficiency: CNC precision processing is usually a point-by-point or line-by-line processing method. For large-area mobile phone casings, the processing efficiency is relatively low. Mobile phone casings usually need to be mass-produced in a short time, so higher processing efficiency is required.
Material waste: CNC precision machining usually requires the entire workpiece to be fixed on a fixture before processing, and then processed point by point or line by line through the tool. For large-area workpieces such as mobile phone casings, using CNC precision machining methods may lead to a lot of material waste.
Surface treatment limitations: CNC precision machining usually cannot meet the special requirements of the surface of the mobile phone casing, such as smoothness, texture, anti-fingerprint coating, etc. Traditional injection molding, die-casting and other processing methods can better meet these requirements.
Complexity limitations: CNC precision machining has better processing results for parts with complex shapes and structures. However, for workpieces with large areas and many curves such as mobile phone casings, there may be processing difficulties and limitations.
In summary, although CNC precision machining has advantages in some areas, in terms of mobile phone casing processing, it is usually not the first choice due to factors such as high cost, low processing efficiency, material waste, surface treatment limitations, and complexity limitations. Way. In contrast, traditional processing methods such as injection molding and die-casting are more suitable for the mass production of mobile phone casings.

When precision CNC machining of aluminum alloys, it is very important to select the appropriate cutting fluid. Here are several commonly used cutting fluid types:
Water-soluble cutting fluid: Water-soluble cutting fluid is a common type of cutting fluid that is made of water mixed with additives. It has good cooling and lubrication properties, which can effectively reduce the processing temperature, extend tool life, and improve surface quality. For precision CNC machining of aluminum alloys, it is better to choose a water-soluble cutting fluid that contains anti-corrosion and antioxidants.
High-Performance Cutting Fluids: High-performance cutting fluids are typically synthetic liquids that provide excellent cooling, lubrication, and rust-preventive properties. They are able to provide higher cutting speeds and longer tool life while maintaining lower processing temperatures. For high-speed, high-precision precision CNC machining of aluminum alloys, using high-performance cutting fluid can achieve better processing results.
Dry machining: Dry machining means that no cutting fluid is used during the machining process, but cooling and lubrication are carried out by air or other means. Dry machining can reduce the use and disposal costs of cutting fluid while avoiding the impact of cutting fluid on the environment. However, dry machining may cause problems such as excessive processing temperatures and accelerated tool wear for precision CNC machining of aluminum alloys, so evaluation and selection need to be made based on the specific situation.
When choosing a cutting fluid, in addition to considering its performance characteristics, you should also pay attention to factors such as compatibility with aluminum alloys, environmental friendliness, and operating safety. The best cutting fluid selection should be evaluated based on comprehensive factors such as specific machining requirements, equipment conditions, and material properties, and should follow relevant safe operating procedures and regulations.

CNC professional machining and precision mechanical parts processing are two different concepts, and there are some differences in scope, requirements and technology. The following are the differences between CNC professional processing and precision machinery parts processing:
range:
CNC professional machining usually refers to the use of computer numerical control (CNC) technology for the processing of various materials, including metal, plastic, wood, etc. It can range from simple parts to complex structures.
Precision mechanical parts processing focuses more on the processing of high-precision and high-demand mechanical parts, which are usually used in precision instruments, aerospace, medical equipment and other fields.
Processing requirement:
CNC professional processing focuses on production efficiency and cost control, and pursues higher processing speed and lower cost. Although a certain degree of accuracy is also required, compared to precision mechanical parts processing, the requirements for surface quality and dimensional tolerances may be looser.
The processing of precision mechanical parts has higher requirements on dimensional accuracy, surface quality, shape complexity, etc. High accuracy and tolerance requirements are often required to meet specific functional and assembly requirements.
techinque level:
The technical threshold for professional CNC processing is relatively low. Operators mainly need to master basic skills such as CNC programming, machine tool operation and tool selection.
The processing of precision mechanical parts requires a higher technical level and experience, and operators need to have more in-depth knowledge and skills in machining, including precision measurement, process optimization and processing parameter adjustment.
Equipment required:
CNC professional processing is usually performed using CNC machine tools, which can adapt to the processing needs of different materials and shapes.
Precision mechanical parts processing may require more specialized equipment and tools, such as high-precision CNC milling machines, grinders, wire cutting machines, etc., to meet higher processing requirements.
To sum up, there are some differences in scope, requirements and technology between CNC professional machining and precision mechanical parts machining. CNC professional processing pays more attention to production efficiency and cost control, while precision mechanical parts processing pays more attention to high-precision and high-demand processing, which requires a higher technical level and professional equipment. Choosing the right machining method depends on specific machining needs, materials and requirements
