Metal casing, middle frame
The metal casings and middle frames of digital products commonly use materials such as aluminum alloy, stainless steel, and titanium alloy. The core machining process relies on CNC precision machining, complemented by techniques like laser cutting and fine grinding, to meet the specific material properties and component precision requirements. Below is a detailed introduction to the various machining types and their corresponding application scenarios:
1. CNC milling processing
The core processing technology for machining metal casings and midframes enables the fabrication of complex contours and intricate structures, making it suitable for mainstream materials such as aluminum alloy, stainless steel, and titanium alloy. This process first establishes the rough outline of the casing or midframe; then, precision milling is used to create critical features—including antenna isolation slots, camera cutouts, and button positions—achieving tolerances that can be controlled down to the micrometer level.
2. Drilling and tapping operations
The matching cutting process for the outer shell and middle frame is used to machine various holes required for assembly. For example, screw-fixing holes in mobile phone middle frames, positioning holes for charging interfaces, and micro-holes for heat dissipation on laptop casings—all rely on this process for fabrication.
3. Chamfering and Deburring Operations
Key cutting-assist processes that ensure product safety and assembly compatibility. For example, the edges of aluminum alloy base shells for laptops become smooth and comfortable to the touch after chamfering; similarly, the edges of the charging port on mobile phone frames are deburred to prevent scratches on data cable connectors during assembly.
