The contribution of CNC machining to the rapid development of mobile phones

The mobile phone can be said to be an indispensable electronic product in our daily life. It has promoted the development of our communication era. But did you know that many parts of mobile phones are made by CNC precision parts processing manufacturers? So how much role does CNC precision parts processing team play in our mobile phone manufacturing? Let's take a look at the effect of CNC precision parts processing on mobile phone manufacturing.

Take the iPhone manufactured by Foxconn. IPhone can be said to be a very popular mobile phone brand, and the IPhone body is generally made of aluminum alloy frame, whether it is 5S or IPhone XS Max after 6S, it is aluminum alloy body, and the aluminum alloy body is precision CNC Precision machining by lathe. Almost all the aluminum alloy shells of brand mobile phones are made by precision processing, because this kind of shell is more beautiful, smooth and drop resistant than ordinary shells.

So is it only related to the processing of the mobile phone shell and CNC precision parts? In fact, there are many parts that we can't see, and they are inseparable from CNC precision parts cnc machining. For example, very small screw caps in mobile phones are customized according to the needs of mobile phone manufacturers. There are almost no standards, and the requirements for precision are very high. Therefore, almost all standards are produced by CNC precision parts processing, and many parts such as silver needles in mobile phones are produced by CNC precision parts processing.



Mainly, the four principles followed in the process of CNC precision parts processing have brought good results to the mobile phone shell. details as follows:

1. Benchmark first

In other words, the datum plane must be processed first. In the processing process, the surface as the positioning reference must be processed first in order to provide a precision reference for subsequent processing as soon as possible.

2. Division of processing stages

The appearance of high processing quality can be divided into three stages: rough processing, semi-finishing and finishing. Its main purpose is to ensure processing quality; facilitate the scientific application of equipment; facilitate the arrangement of heat treatment processes; facilitate the detection of blank defects.

Third, the front surface of the hole

For parts such as boxes, brackets, connecting rods, etc., the plane should be machined before the holes are machined. In this way, the holes can be machined and die casting  by plane positioning, which ensures the position accuracy of the plane and the holes, and facilitates the processing of the holes on the plane.

Four, complete

The finishing of the main surface, such as grinding, honing, finishing, rolling, etc., should be placed at the end of the process route. The general principles of precision parts processing routes and the formulation of precision parts processing procedures can be divided into two parts. First determine the process route of the part processing, and then determine the process size of each process, the equipment and process equipment used, the amount of cutting, the quota of working hours, etc.
