CNC Machined Aluminum Bicycle Bike Sprocket

Manufacturing relies on precision CNC milling to achieve consistent tooth profiles and accurate bolt circle diameters (BCD) for secure crank arm attachment. The vibrant blue and green finishes indicate an anodizing treatment, which provides essential corrosion resistance and surface hardness against wear. Controlling flatness across the ring face is vital to prevent chain skipping or noise, requiring stable fixturing and stress-relief strategies during machining.
