The automobile has thousands of parts, almost car components are closely connected with CNC machining. As the heart of the car, the engine has a complicated manufacturing process and high precision requirements. The cylinder block is the supporting part of other parts and is the largest part of the engine. It starts with die-casting and CNC machining, and then precise boring. The plunger completes the same process. The connecting rod is manufactured by roll forming and CNC machining. In automobile manufacturing, all of these are closely connected with the precision machining of precision auto components.
With the development of CNC machining, it will enter automobile production more deeply, while serving and accelerating the development of the automobile industry. The CNC machine converts the digital files into sequential computer instructions and then sends them to power tools such as drills, lathes, or milling machines. The tool converts a piece of material into a finished precision auto component by cutting in the right position, thereby providing higher precision than traditional machining. In this blog post, we want to illustrate the importance of CNC machining for precision auto parts by talking about the main advantages of CNC machining for the automotive industry.
People pay more attention to the beauty of modern car bodies. To obtain better aerodynamics and crash safety, reduce driving resistance, and improve safety, the design of higher-order equations on the surface makes it more complicated. Many car components are difficult to process on automobiles, such as automobile engines, gearboxes, and chassis parts, which need to be processed by 5-axis machining centers. For certain auto parts, CNC machining (including tasks such as drilling and boring through computer control and automation) is now an ideal choice for prototyping and production.
• Precision & Accuracy
Many automakers prefer CNC machining because it allows for the manufacture of precision auto components of the highest quality. The autonomy of the process makes the possibility of errors extremely small, and the best machining settings can provide tolerance of about 0.001 inches. This is very advantageous because the automotive industry requires the highest standards and such high tolerances. After all, the failure of key components can have serious consequences for the end-user.
The same car component can be generated numerous times by CNC machining, without any differences between parts. Hence, as manufacturers manufacture vast quantities of individual pieces, it proves incredibly useful. It is especially beneficial in the automobile sector, as the automotive industry generates and sells dozens of millions of vehicles per year, meaning the competition for vast amounts remains steady. It is more cost-effective to produce large quantities of products through CNC processing because the processing labor intensity of the product itself is lower compared to the introduction stage. This is because the initial stage involves the digital design of components, preparation of G codes, and selection of materials.
The biggest advantage of CNC machining auto parts is the speed it provides. Mechanical processing is carried out automatically by a computer, so there is no need to consider any human factors in the process. This advantage becomes more obvious when processing parts in large batches, especially because computer instructions can be repeated as many times as needed.
Although CNC is much faster than conventional machining, in some cases conventional machining may be faster. For example, when only one section of the precision auto component needs to be produced, the time it takes to create instructions may exceed the time it takes to manually process a single-car component.
• Car Engine Components
CNC machining can be used to manufacture several important components of internal engines. For example, a large aluminum block can be processed into an engine, and the metal structure includes an engine cylinder in which a movable piston moves up and down. Though programming a CNC machine tool is a time-consuming process and needs a high degree of ability, it can execute its instructions without assistance once the machine tool is ready. This ensures multiple engine blocks can be continually manufactured without major labor rises. The cylinder head is a car component that surrounds the cylinder above the block and is also jointly produced using CNC machining technology.
• Precision Auto Components for Lighting
Aluminum and other metal machining are some of the most important CNC technology applications in the automotive industry but materials such as acrylic glass or acrylic can also be used to make other important parts. By processing acrylic, manufacturers can produce lighting for vehicles, including headlights and interior lighting. Although these acrylic parts need to be ground and polished after CNC machining, the whole process is still relatively fast, which allows automakers to make new lamp prototypes for their cars. Acrylic is usually used as a shatterproof substitute for glass and can be made into windows, transparent shields, fish tanks, and other precision auto components.
• Other Car Components
CNC machining can be used to manufacture other parts of the automobile industry including, but not limited to, suspension components, exhaust components, carburetor housings, parts of the hydraulic system, bushings, and valve holders. Because CAD can alter the design of the component easily, manufacturing technology is also especially useful for customizing vehicles and their components.
Tools are simply the process of designing and engineering tools used to manufacture car components and other parts. Therefore, in the automotive industry, tools must be related to specially designed tools, and automakers can use these tools to forge auto parts. Although tools have always been a key part of automotive production, the market today is transitioning from high-volume, low-mix volume to small-volume, high-mix volume automotive production. In short, in the past one tool could produce many different parts. Now, a unique tool is needed to make every part of the new car. Manufacturers are also releasing new models and redesigned models at a faster rate than before. Therefore, companies that create these tools must increase efficiency to meet the growing demand for more tools. Due to the wide variety of tools used in modern manufacturing, automobile parts can be manufactured in several different types. For example, CNC machining is a production method that involves the mass production of parts. The worker feeds the raw materials into the machine, and the machine triggers an automatic process to cast the parts. Engine cylinder heads, gearboxes, gearboxes, flywheels, engine locks, wheels, and water pumps are just some of the parts that rely on this manufacturing method.
