Precision parts processing plays a role in mobile phone case

Mobile phones can be said to be necessary electronic products in our daily life, which promotes the development of our communication era. But do you know that many parts in the mobile phone are processed by precision parts processing manufacturers? The following is a detailed understanding of the role of precision parts processing in the mobile phone manufacturing industry by Shenzhen fuchengxi technology. Take the iPhone produced and developed by Foxconn for example. The iphone can be said to be a popular brand of mobile phones, and the body of the iphone is generally aluminum alloy frame, and whether it is 5S or later 6 s- The iPhone XS Max is an aluminum alloy body, and the aluminum alloy body is produced by precision machining of precision CNC lathes. The aluminum alloy shells of almost all brand mobile phones are made by precision machining, because such shells are more beautiful, smooth and resistant to falling than ordinary shells. So is only the mobile phone shell related to Precision Machining? In fact, there are still a lot of parts that we can't see. In fact, they also have an inseparable relationship with precision machining, such as very small nuts inside mobile phones, because these nuts are actually customized according to the needs of mobile phone manufacturers, there is almost no standard, and the accuracy requirements are very high, so almost all rely on the processing of precision parts, there are also many parts such as silver needles in mobile phones that rely on precision machining. Mainly the four principles followed in the processing of precision parts have brought good effects to the mobile phone case. As follows: 1. The reference surface is processed first, and the appearance of the parts as the positioning reference should be processed first in the process of mechanical processing, so as to provide a fine reference for the processing of subsequent processes as soon as possible. 2. The appearance with high mechanical processing quality requirements in the processing stage is divided into the processing stage, which can generally be divided into three stages: rough processing, semi-finishing and finishing. Mainly to ensure the quality of processing; Conducive to scientific application equipment; Easy to arrange heat treatment process; And easy to find blank defects. 3, the first surface after the hole for the box, bracket and connecting rod and other parts should be processed after the plane processing hole. In this way, the hole can be positioned in a plane to ensure the position accuracy of the plane and the hole, and the processing of the hole on the plane is convenient. 4, finishing processing the main appearance of finishing processing, such as grinding, honing, fine grinding, rolling processing, etc. , should be placed at the end of the process route. The general principle of drawing up the processing route of precision parts and the formulation of the processing procedure of precision parts can be roughly divided into two links. The first is to formulate the process route for parts processing, and then determine the process size, equipment and process equipment used in each process, as well as cutting specifications and working hours quota. In fact, many things in our daily life are common in precision machining and precision parts machining, But We laymen can't pay attention to them.
