I. The Precise Process of CNC Machining

CNC machining can precisely control every detail of the bicycle chainring with an accuracy of up to ±0.01 millimeter, such as the tooth shape, each hole diameter, and the overall contour processing of the bicycle chainring. Its characteristics are as follows:

1. High Precision
   It can almost perfectly replicate the chainring model on the design drawing into the actual material, ensuring that the dimensional tolerance of the chainring is controlled within a very small range. For example, the machining accuracy of the tooth shape can reach ±0.01 millimeter, which makes the meshing between the chain and the chainring smoother, improves the efficiency of power transmission, effectively reduces the jumping and wear of the chain, and provides riders with a stable and efficient pedaling experience.
2. Exquisite Appearance
   Thanks to the high-precision control of CNC machining, the chainring can be made more exquisite. After anodizing, there are almost no visible tool marks and flaws, making your product more marketable and deeply loved by consumers.

II. Applicable Bicycle Models

CNC machining can process bicycle chainrings of different shapes and can be customized according to customers' drawings. It is applicable to different types of bicycles, such as mountain bikes, road bikes, and city commuter bikes, which have different performance requirements for chainrings. CNC machining technology can adapt various high-performance materials for chainring manufacturing according to different needs. This aluminum alloy chainring can achieve a lightweight design while ensuring a certain strength through CNC machining, reducing the overall weight of the bicycle and enhancing the riding flexibility. For competitive road bike chainrings that pursue ultimate strength and rigidity, CNC machining of titanium alloy or carbon fiber composite chainrings can fully utilize the advantages of these materials. Through precise cutting and forming processes, the excess material is removed, making the stress distribution inside the material more reasonable, further enhancing the durability and fatigue resistance of the chainring. Even in high-intensity competitions and long-duration rides, it can maintain excellent stability.
