Micro-threaded hole
The threaded holes in digital products are typically tiny, designed for screw fastening and component assembly. The materials used for machining mainly include aluminum alloys and stainless steel. The core cutting processes revolve around tapping and thread milling; in some specific applications, special machining methods such as extrusion molding may also be employed, as detailed below:
1. Tap threading machining
The most common machining method is suitable for small- and medium-diameter threaded holes, such as those used for smartphone frame screw holes and laptop casing mounting holes (common specifications include M1.2 and M3). During machining, first drill a pilot hole that matches the thread size, then use a tap to cut or form the threads.
2. Thread milling machining
Large-diameter threaded holes suitable for stainless steel components, or special threaded holes with high precision requirements in high-end equipment. Utilizing the helical interpolation function of CNC machines, these threads are milled using a thread milling cutter, resulting in a surface finish superior to that achieved by conventional tapping.
3. Buckle-clip processing (emergency auxiliary method)
This method is intended solely for emergency machining of single-piece, small-batch production or special-pitch threaded holes—such as non-standard threaded holes in customized digital accessories. During machining, a threading tool is mounted on the boring bar, and the tool path is controlled by a CNC machine to complete the thread cutting. It is used exclusively to address processing challenges in specialized scenarios.
