What Is Carbon Fiber?

Carbon fiber is a polymer, sometimes called graphite fiber. It is a very strong and light material, five times stronger than steel and twice as rigid as steel. Carbon fiber is made of carbon atoms through chemical and mechanical processes, and has a very high strength-to-weight ratio, so it is favored in many industries such as aerospace, automobile, military and leisure applications.

Main Application of CNC Cutting Carbon Fiber

Carbon fiber is a material with incredible strength and weight, and can be cut by CNC machine tools. Because of its high rigidity and ability to absorb impact energy, carbon fiber is a popular composite material in industries where safety is the most important. We use CNC machine to cut carbon fiber, and make any simple or complex carbon fiber parts for you. The following are the main applications of CNC cutting carbon fiber:

• Drones
• Motorcycles
• Robotics
• Toy racing car

In fact, in addition to the application types listed above, there are more carbon fiber applications that can be processed through CNC. View the CNC carbon fiber parts we manufacture.

Precautions for Carbon Fiber CNC Machining

When using CNC to process carbon fiber products, problems such as delamination and tearing of carbon fiber materials are often encountered. In addition, the carbon fiber composite material formed by the fusion of carbon fiber and resin matrix is not difficult to process after curing. However, due to the low melting point of the resin, there may be burning during the processing due to overheating, which can cause performance damage to the carbon fiber product. CNC technicians need to fully consider the relationship between cutting force and deformation to ensure that processing does not affect quality.

When CNC precision machining carbon fiber products, the impact of oil pollution on the products should also be considered. It is possible to perform dry cutting without adding coolant, which not only softens and burns carbon fiber products, but also causes excessive tool wear. Therefore, it is necessary to choose a suitable tool.

How to Choose Cutting Tools for CNC Cutting Carbon Fibers?

It is best to choose CVD diamond cutting tools for CNC machining of carbon fiber composite materials, because this type of tool has the best wear resistance, smooth cutting edges, and the best quality. Alloy cutting tools can cause serious wear and tear during processing, and are prone to burning out products. In the process of processing carbon fiber composite materials, an appropriate small value should be selected for the front angle of the machining tool, which can effectively dissipate heat and increase the cutting edge strength. However, be careful not to choose a tool that is too small to avoid low sharpness and inability to process. In addition, in order to reduce wear on the tool, a larger value is selected for the back angle of the tool.

In addition to CNC cutting, CNC milling, CNC turning and other processing methods, 3D printing is also a popular method for manufacturing carbon fiber parts.
