II. Technical principles and characteristics of CNC wheels
(1) Working principle of CNC wheels
- CNC programming and processing flow
CNC programming is the core link in the processing of CNC wheels. Through computer-aided design (CAD) and computer-aided manufacturing (CAM) software, engineers can precisely design the shape and size of wheels and generate corresponding CNC programs. During the processing, the CNC system controls the tool movement trajectory, cutting speed, feed rate and other parameters of the machine tool according to the program instructions to achieve high-precision processing of wheels.
For example, in an automotive wheel manufacturing enterprise, technicians first use CAD software to design a three-dimensional model of a new type of wheel, and then generate a CNC program through CAM software. After inputting the program into the CNC machining center, the machine tool automatically performs processing operations such as milling, drilling, and boring according to the program instructions, and finally produces a wheel that meets the design requirements. - Automated measurement and program generation
To ensure the processing accuracy of wheels, automated measurement technology is usually used in the processing of CNC wheels. For example, some advanced CNC wheel wire drawing lathes are equipped with an automatic measurement system that can measure the dimensional and shape errors of wheels in real time during the processing and automatically adjust the processing parameters according to the measurement results to ensure the processing accuracy of wheels.
In addition, some CNC systems also have the function of automatically generating programs. By analyzing the three-dimensional model of wheels, the system can automatically generate the optimal processing path and program to improve processing efficiency and quality.
(2) Characteristics of CNC wheels
- High precision and stability
CNC wheels use high-precision processing equipment and advanced processing technologies, which can ensure that the dimensional accuracy and shape accuracy of wheels reach a very high level. For example, the circumference accuracy of some high-end CNC wheels can be controlled within ±0.05mm, and the flatness of the mounting surface can also reach an extremely high standard. This enables the wheel to maintain good balance during high-speed rotation, reduce vibration and noise during vehicle driving, and improve driving stability and comfort. - Versatility and applicability
The application of CNC technology makes the processing of wheels more flexible and diverse, which can meet the needs of different vehicle models and users. CNC wheels can process various complex shapes and structures, such as streamlined spokes and internally hollowed out lightweight designs. At the same time, CNC wheels can also adapt to the processing of different materials, such as aluminum alloys, magnesium alloys, etc., providing more choices for the lightweight and high-performance of wheels.

IV. Technological innovation directions of CNC wheels
(1) Material technology innovation
- Advantages of high-strength aluminum alloys
High-strength aluminum alloys are currently one of the most commonly used materials for CNC wheels. Compared with traditional steel materials, aluminum alloys have the advantages of low density, high strength, and good thermal conductivity. CNC wheels made of high-strength aluminum alloys can not only effectively reduce the unsprung weight of vehicles, improve the fuel economy and handling performance of vehicles, but also improve the heat dissipation performance of the braking system and reduce brake fade.
For example, some high-end automotive brands use high-strength aluminum alloy wheels, which significantly improve the performance of vehicles. At the same time, with the continuous progress of aluminum alloy material technology and the continuous emergence of new high-strength aluminum alloy materials, more choices are provided for the lightweight and high-performance of CNC wheels. - Application prospects of magnesium alloys
Magnesium alloys are materials lighter than aluminum alloys and have the advantages of low density, high specific strength, and good shock absorption performance. In the manufacturing of CNC wheels, the application of magnesium alloys can further reduce the weight of wheels and improve the fuel economy and handling performance of vehicles.
However, the chemical properties of magnesium alloys are relatively active and are easily corroded, which brings certain challenges to the manufacturing and use of magnesium alloy wheels. At present, some enterprises and scientific research institutions at home and abroad are actively carrying out research and development work on magnesium alloy wheels, and by adopting special surface treatment technologies and manufacturing processes, the corrosion resistance and reliability of magnesium alloy wheels are improved. It is believed that in the near future, magnesium alloy wheels will be more widely used in the automotive industry.

- Forging process to improve quality
The forging process is one of the important methods for manufacturing high-performance CNC wheels. By applying huge pressure to the metal blank to cause plastic deformation, wheels with dense internal structure and excellent mechanical properties can be manufactured. The strength and toughness of CNC wheels manufactured by the forging process are much better than those of cast wheels and can withstand greater loads, which are suitable for high-performance cars and racing cars and other fields.
For example, some high-end sports car brands use CNC wheels manufactured by the forging process, which can not only improve the performance and safety of vehicles but also enhance the aesthetic appearance of vehicles. With the continuous progress of forging technology and the reduction of costs, the application of the forging process in the manufacturing of CNC wheels will become more and more extensive. - 3D printing to achieve personalized customization
3D printing technology is an emerging manufacturing technology with the advantages of rapid prototyping and personalized customization. In the manufacturing of CNC wheels, 3D printing technology can realize the rapid manufacturing and personalized customization of wheels to meet consumers' personalized needs.
