1 What is CNC? Which products use this process? As one of the important industries in the modern science and technology industry, tablet PCs have already had a significant impact on the traditional computer industry. Although there are many flat products on the market, from the perspective of product molding, there are mainly three types. : Injection molding, stamping and CNC forming, and among these three, the CNC process is the most complicated, and the products after molding generally appear in a relatively high-end posture. What does the initial CNC process look like for a flat-panel product? What major improvements have been made in these years? With the above two questions, let’s take a look at the growth of the CNC process. ■ What is CNC? CNC is commonly known as “CNC machine tool”. I believe many people have heard of this concept. It is an automated machine tool controlled by a program. The control system can logically process a program with control code or other symbolic instructions, and decode it by a computer, so that the machine tool performs a prescribed action, and a piece of original metal sheet is processed through a long time for precision processing. The shape you want. Why is it so popular? CNC process analysis The control system can logically process the control code and process the blank into semi-finished finished parts by tool cutting ◆Which products are used for molding and applying this technology? In practical applications, CNC molding technology combined with metal materials can create more stringent product precision and bring better texture. At present, the most representative products in the tablet market are Apple iPad series products and Nokia N1. CNC forming technology is more expensive, resulting from incredible accuracy and precision, and each piece is carefully crafted. At present, CNC forming technology is also used in the production of precision parts in the aerospace and racing industry, which is why high-end flat products use this process. ■ The first generation iPad makes more people aware of the CNC process The first generation of iPad released on January 28, 2010, and quickly won the market, and its success in addition to its high performance, CNC process back shell process is also one of the highlights, its color is still on its shape “high face “Value” has gotten more consumers’ likes. It can be said that the adoption of the iPad generation of CNC technology allows more people to understand the process. Why is it so popular? CNC process analysis The first generation of iPad is on sale. The high-precision and high-complexity grinding CNC process back shell is a lot of “additional points”. ◆ The first generation of iPad was initially applied to the fuselage thickness of 13.4mm The first generation of iPad body thickness is 13.4mm, CNC molding technology with magnesium alloy back shell, bringing a strong metal texture to the product. Although from the current point of view, the thickness of the fuselage is somewhat unsatisfactory, but in the background, the process has just been applied to the flat product, it is not easy to do so. Why is it so popular? CNC process analysis The first generation of iPad was initially applied to the fuselage thickness of 13.4mm. The process is not so perfect. ◆The focus is more on the appearance. There is not too much design inside. At the beginning of the design, the main focus of the iPad generation of the back shell of the iPad is the appearance. When the grip is held, the body is smooth, but there is just the right graininess, which makes the hand feel better when playing the product. In addition, the four corners of the back shell are rounded, which increases the portability and gives a small visual experience. Why is it so popular? CNC process analysis The iPad generation of the back cover of the iPad using the CNC process has a certain graininess. In terms of internal design, the internal performance of the iPad back shell is relatively rough, the internal screw fixing method and the “baffle” design are more abrupt, and the overall design of the back shell is poor. However, the existence of its stripe design can better provide space for components, ensure the performance of the product, and the thickened design of the back shell key, to a certain extent, to ensure the fixing mode of its function keys. Why is it so popular? CNC process analysis In addition to the CNC technology, the internal screw fixing method of the iPad and the “baffle” design are more abrupt. It can be seen that the initial CNC process is applied to flat products, and it is still rough. There are still many areas for improvement in internal design, but the strict product precision and outstanding texture make the process above the injection molding and stamping process. . Of course, this is only the original CNC process. How has the process progressed to the present? Let’s move on. Product: N1 Nokia Tablet PC 3 back shell exterior process enhancements More beautiful and refined ■The CNC process is becoming more mature. Both Nokia N1 and iPad Air 2 use this process. The CNC process has developed to the present day, and more and more flat products are used. The most representative ones are Apple’s latest series of iPad Air 2 and Nokia N1 tablets. Both of these products use CNC technology. What improvements have been made in the process today? What are the improvements in design? Why is it so popular? CNC process analysis Nokia N1 uses the latest CNC process back shell ◆Process improvement, the appearance is more beautiful In appearance, the products made by this process are more “slender”, the overall visual sense of the back shell is enhanced, and the appearance of the product becomes more beautiful (of course, this has a lot to do with the upgrade of the screen), and around it. The border becomes more rounded, not a rigid “frame” design, more comfortable when held, this change can be said to be a process improvement. Why is it so popular? CNC process analysis The border around the Nokia N1 has become more rounded, not a rigid “frame” design. In addition, there are certain improvements in the details of the key position, so that the key position does not stay on the side frame, but is close to the back plate to a certain extent, so that reducing the thickness of the body does not affect the user operation. It can be said that it is two birds with one stone. The realization of this design depends to some extent on the improvement of the process. Why is it so popular? CNC process analysis The details of the key position are also improved. It is easy to operate and more beautiful. The concave design of the interface has also been improved in the previous technology. There is a certain gap between the keys. The design makes the volume key and the shutdown key set adjacent to each other. . Why is it so popular? CNC process analysis The gap between the two keys is close and small. The precision of the CNC process perfectly supports the design. It can be seen that the current CNC process has a great improvement in appearance compared to the previous one. The round frame, the appearance is more fine, the grinding process is more mature, and the high-precision polished body has an industrial design beauty. And these are just the improvement of the appearance process, so is there a qualitative improvement in the internal process of the back shell? Please look down. Product: iPad Air (16GB/WiFi version) Apple Tablet 4 internal design Beautiful and reasonable design ◆Internal design Beautiful and reasonable design Compared with the outside of the back shell, it is more attractive to the inside of the CNC back shell. Now the CNC has become “clean and neat” inside the back shell, and the screw fixing has become “small”. The position is close to the border and is not designed. The awkward feeling, the overall design has been greatly improved. Why is it so popular? CNC process analysis The iPad Air 2 back shell uses CNC technology, and the interior becomes “clean and neat” ◆Reducing the overall thickness of the back shell, paying more attention to detail At the beginning of the CNC process application, the thickness of the four peripheral corners is the same as the frame, and there is no special design. Nowadays, the corners of the machine are thickened to deal with the strong impact, and this part is the most easy to bump on the flat, so it should be well protected. On the one hand, the design reduces the weight of the fuselage (reducing the overall thickness of the back shell) and enhances the overall firmness of the fuselage. Why is it so popular? CNC process analysis Nokia N1 back shell four peripheral corner thickening treatment to enhance the overall strength of the fuselage At the interface of the fuselage, CNC technology products are now fixed with a complex structure to ensure the durability of the interface. To know if your tablet is awkward, then you need to charge the tablet every day, and the charging cable is repeatedly plugged and unplugged. It is a test of the durability of the interface. Nokia is considering this point. The interface utilizes a complex structure to make it stable and fixed. Why is it so popular? CNC process analysis CNC process products are fixed with a complex structure to ensure the durability of the interface In addition to the above, a certain groove is added at the inner frame to play the role of fixing components. It can be said that it is a technological innovation, and the groove does not cover the surrounding frame, but appears in the presence of components. The location of the process is aimed at better and better fixing components. Why is it so popular? CNC process analysis Groove design is also an embodiment of precision manufacturing ■ written at the end: From the generation of iPad application CNC technology to now, it has been more than four years, during this time, whether it is the appearance of the back shell or its internal integration, there is a significant improvement, it can be said that the current process is the highest precision The grinding process of complexity. After four years, what kind of height will the CNC process reach? We can’t be sure of anyone. I believe that with the improvement of design in the future, the process will be more precise and reach a realm that we can’t imagine.
