Carbon Fiber Backingless Drilling Technology

everybody knows carbon fiber Due to the high modulus, high hardness, and high specific strength, it is a typical difficult-to-machine material. When drilling, the composite material is prone to defects such as delamination and tearing, and the tool wear is serious. When drilling in practical applications, an aluminum plate needs to be placed on the bottom of the material, but some products are limited by the structure and cannot be installed at the exit of the hole, so the quality of the hole machining cannot be guaranteed.
“In the article, I have already told you that the reason for the delamination and tearing of carbon fiber drilling is mainly caused by excessive axial cutting force. However, how to drill holes for products with irregular structures that cannot be placed on the backing plate, and let China Be-cu Prototype Material Technology Co., Ltd. explain to you!
In this case, the electric spindle can be used for high-speed drilling, and there is only a slight fluffing phenomenon caused by uncut fibers at the exit, which can meet the requirements of use. 2. From the perspective of torque, it is much more stable than the hand electric drill. High-speed drilling is an effective way to solve the problems of carbon fiber tearing and delamination.
Through the years of machining experience of China Be-cu Prototype Material Technology Co., Ltd., increasing the rotational speed is an effective method to reduce the axial force. Under the condition of a certain feed rate, the higher the drill speed is, the smaller the drilling force is. , The high-speed drilling technology can completely realize the drilling of carbon fiber composite materials without backing plate, solve the problem of carbon fiber tearing and delamination, and ensure the quality of hole machining.
China Be-cu Prototype Material Technology Co., Ltd. is a professional carbon fiber manufacturer. The conventional products include carbon fiber board, cloth, rod, tube, aramid cloth, mixed cloth and so on. Various special-shaped parts can be processed and customized for customers. The product specifications are complete, the tolerances are small, and the accuracy meets the use specifications. China Be-cu is your trusted partner!
