Manufacturing Process and Technical Challenges

In carbon fiber CNC services, machining carbon fiber composites is a very challenging task because its high hardness and anisotropic properties can easily lead to delamination, burrs or tool wear. For example, we once machined a carbon fiber body panel for an automotive customer, which contained multiple curved contours and small holes with a diameter of 1 mm, with a tolerance requirement of ±0.02 mm and a smooth surface without burrs. The difficulty is that the layered structure of carbon fiber is prone to delamination or cracking during high-speed cutting while maintaining the accuracy and surface quality of the hole.

Technical difficulties and solutions:

Challenges: The high hardness and fiber orientation of carbon fiber composites lead to rapid tool wear, and delamination and burrs are prone to occur during processing.

Solution

Special tools: Diamond-coated tools are selected, combined with optimized cutting speeds and low feed rates to reduce tool wear and prevent material delamination.

Water-cooled processing: High-pressure water cooling technology is used to reduce the temperature in the processing area and reduce the impact of thermal stress on the carbon fiber layer.

Step-by-step processing strategy: Through multi-stage roughing and finishing, the part structure is stabilized first, and then high-precision hole processing and surface finishing are performed to ensure that there are no burrs and cracks.

Through these measures, we successfully achieved a tolerance of ±0.02 mm, the hole positioning error was controlled within 0.01 mm, the surface roughness reached Ra 1.2 microns, and the parts passed the customer's rigorous performance and appearance tests. This reflects our professional capabilities in the field of precision CNC processing.
