On the difficulty of CNC machining of all-metal mobile phones: resulting in insufficient production capacity
On the difficulty of CNC machining of all-metal mobile phones: resulting in insufficient production capacity…
In fact, the mobile phone metal CNC industry seems to have a relatively low threshold. It can start production with the purchase of related equipment. However, it is not easy to do it well. It is also a manufacturer of metal CNC processing. The technical level is different, and the industry accumulation is different, which will affect its Production yield level. In other words, to improve the CNC processing yield to a higher level, for most manufacturers, it is still a big problem.
A well-known CNC factory person in the industry said: "Because all metal machining is very complicated, and every process is very important, especially CNC machining and secondary processing, a slight carelessness may cause the entire product to be scrapped."
The plastic case only needs to open the mold to achieve mass production, the yield is basically over 90%; the metal frame structure can already achieve 85-90% yield, but the large-area, all-metal body CNC The product yield is currently 75% and it is already very high.
If 75% of the yield is still acceptable, then the secondary processing will make this data continue to decline, and the mobile metal process is impossible to directly use the metal casing, it must be secondary processing. The “secondary processing” process includes surface treatment processes such as polishing, wire drawing/blasting, and anode. The cost of the all-metal CNC product to the secondary processing is already high. If problems occur in these processes, such as scratching during drawing A little bit, it takes a lot of manpower and material resources to make up for it, and in many cases it can't be repaired, which has a great impact on the yield.
In addition, the reason why "secondary processing" causes a large yield loss, in addition to the problems caused by its own processing, is also affected by the processing effect of the previous section CNC. Since the all-metal CNC product is made of a whole piece of metal by CNC machining or forging, punching and pressing, the processing area is large, it is easy to cause scratches in the CNC machining process, and it is difficult to avoid the occurrence of the shock pattern, which is the latter. The difficulty of secondary processing has buried the foreshadowing.
I don’t know how many CNC processing plants are stumped on the issue of “seismic pattern”. It is understood that this year a metal CNC processing plant in the production of metal fuselage due to the problem and delay can not improve the yield, and ultimately can only reduce the CNC processing speed, re-adjust the CNC process to reduce the shock pattern, thereby improving " The pass rate of secondary processing. It is precisely because of this that the delivery efficiency is sacrificed.
In the face of this embarrassing and helpless situation, industry insiders have lamented: "For the metal CNC industry, the yield is the core competitiveness, and to improve the yield, the secondary processing is a roadblock."
From the multi-faceted narrative of this number of people above, it is not difficult to see that the “honing” of a metal mobile phone from production to listing is one layer after another, and the metal mobile phone you use is trampling a lot. The best in the product. And manufacturers are very aware of this process will spend relatively more words or costs on a mobile phone.
