The shell of 3C electronic equipment is an important embodiment of its external image, and it is also an important application field of CNC custom processing. In the case of a mobile phone, for example, CNC machining can create a three-dimensional design through precise tool path planning. In the process of processing, the tool can carve out fine textures on the surface of the shell, such as frosted textures, imitation leather textures, etc., to enhance the texture of the phone shell. For the metal shell, the anodizing treatment after CNC machining is better, which can make the shell show a uniform and bright color, while maintaining the smoothness of the surface.

In the processing of tablet computer shell, CNC custom machining also plays a key role. Through CNC machining, the shell edge can be rounded to improve the user's comfort. Moreover, for some tablet computer back cover with special materials or complex designs, such as the back cover with fine structures such as heat dissipation holes and speaker holes, CNC machining can ensure the accuracy and quality of these structures and ensure the normal realization of their functions.

Within 3C products, the processing of many precision parts is the key to ensuring product performance. CNC custom machining technology provides an efficient and precise solution for the production of these parts. For example, in the processing of mobile phone motherboards, CNC equipment can accurately process a variety of chip slots, line card slots and other tiny structures to ensure the electrical performance and stability of the motherboard.

For the UAV parts processing, because the UAV has strict requirements for the strength and weight of the parts, CNC machining can reduce the weight of the parts by optimizing the tool path and cutting parameters under the premise of ensuring the strength of the parts. For example, key parts such as the wing skeleton and motor base of the UAV, after CNC processing, can reduce the overall weight of the UAV and improve flight performance while meeting the carrying capacity.

In the process of CNC custom machining, the design of fixture is very important. The appropriate fixture can ensure the stability and positioning accuracy of the workpiece during the processing, thus improving the processing quality. For the processing of 3C electronic parts, different types of accessories require different fixture designs.

For example, when processing small parts such as mobile phone keys, the use of vacuum adsorption fixtures can effectively prevent the displacement of parts during processing. For the slender shape of the workpiece such as the tablet computer frame, a special tray clamp can be designed to ensure its coaxial degree during processing. These targeted fixture design schemes are based on the characteristics of CNC custom processing and the shape and size requirements of 3C electronic accessories, which provides a strong guarantee for the smooth process of processing.

Through practical cases, we can more intuitively feel the excellent results achieved by CNC custom machining in the field of 3C electronic accessories.

A well-known mobile phone brand has adopted CNC custom machining technology in the shell processing of its flagship model. Through CNC machining, the mobile phone shell has realized the design of ultra-narrow border, and the error of the border width is controlled within a very small range, which improves the screen proportion of the mobile phone. At the junction of the glass material on the surface of the shell and the metal frame, CNC processing ensures the fitting accuracy of the two, making the appearance of the mobile phone more exquisite. At the same time, in the processing of the back cover of the mobile phone, the CNC equipment has carved out a unique texture pattern, which not only increases the beauty of the mobile phone, but also provides better anti-slip performance, which has been widely praised by consumers.

A professional drone manufacturer used CNC custom machining in the casing production of its new drone. The drone casing is made of a high-strength carbon fiber composite material that CNC machining was able to precisely cut and sand, giving the shape of the casing exactly the aerodynamic design requirements. At the connection part of the shell, CNC machining ensures the smoothness and tightness of the interface, improving the flight stability of the drone. In addition, the structure of the heat dissipation hole and sensor mounting hole reserved on the casing by CNC machining has accurate position and appropriate size, which effectively ensures the heat dissipation performance of the drone and the normal operation of various functions.

In the processing of the back cover of a tablet computer, the manufacturer successfully solved the problem in the processing of the back cover by using CNC custom processing technology and vacuum suction fixture. Due to the large and thin rear cover area of tablet computers, traditional processing methods are easy to cause deformation of the back cover. The vacuum fixture can uniformly adsorb the back cover during processing to keep it flat. Through CNC machining, holes are precisely machined on the back cover for mounting cameras, microphones and other components, as well as ventilation slots for heat dissipation. The machining precision of these holes and slots is extremely high, ensuring the accurate installation of the tablet components and good heat dissipation effect.

For the manufacture of a high-end smartwatch, CNC custom machining plays a key role. The case of the watch is made of titanium alloy, and the complex shape of the case is precisely shaped by CNC machining, including the processing of the crown, buttons and other small structures with extremely high precision. In terms of strap processing, the exquisite texture consistent with the case style is achieved through CNC machining, and the shape of the strap that conforms to the wrist curve can be processed according to ergonomic principles to improve the comfort of wearing. At the same time, the tiny parts such as the sensor fixing frame inside the smart watch are also processed by CNC, ensuring the installation accuracy of the sensor and ensuring the accuracy of the health monitoring and other functions of the watch.
