The drilling process of carbon fiber composite materials will produce powdery chips, which will pollute the environment and affect the health of workers. However, at present, the chip is sucked away by a vacuum cleaner manually, because it can only be sucked from the hole entrance area, and cannot be sucked directly when it is generated. Aiming at this main problem, the present invention proposes a brand-new processing system—the air-suction self-removing chip processing system for CFRP processing to provide a technical solution for realizing CFRP green processing. The proposed self-suction chip removal system for CFRP machining includes: 1-machine tool, 2-CFRP, 3-drill, 4-tool holder, 5-spindle, 6-cutting channel, 7-suction/storage device. The working principle of the air-breathing chip removal system for CFRP processing is that when the machine tool drives the drill bit to cut the workpiece, the instantaneous chips generated during the drilling process can pass through the suction hole of the tool, pass through the tool holder, the spindle and the chip removal channel. Enter the storage device to realize the green processing of CFRP.
