Carbon fiber composites possess advantages such as high strength, light weight, high specific modulus, fatigue resistance, and corrosion resistance, making them widely used in fields including aerospace, automotive industry, sports equipment, wind power industry, and robotics. During the machining process, carbon fibers exhibit characteristics of anisotropy, heterogeneity, and high wear resistance, leading to the following machining features:
Material properties cause rapid wear of the machining cutting edge and short tool life;
Machining quality is difficult to control, with poor machined surface quality and effect, and prone to issues such as delamination, burrs, tearing, and pits;
Affected by cutting force and cutting heat, the material’s anisotropy results in significant fluctuations in cutting force during machining; meanwhile, the material has poor thermal conductivity, making it difficult to dissipate cutting heat.
As an enterprise engaged in the R&D and manufacturing of superhard cutting tools, Worldia currently provides reliable corresponding cutting tool solutions for the machining of carbon fiber composites, including turning, milling, and drilling.
Solution Analysis
◎Carbon fiber composites feature brittleness and hardness, poor thermal conductivity, and anisotropy. These characteristics require machining tools to not only have high wear resistance and high strength but also maintain sufficient sharpness at the cutting edge.
◎Worldia’s custom PCD turning inserts, developed based on the actual machining conditions of this case, adopt a non-standard cutting edge design and suitable PCD grade, achieving a tool life 12.3 times longer than that of the original solution.
◎With the advancement of technology and market development, various emerging industries and special-purpose part materials have emerged. As a superhard material and cutting tool manufacturing enterprise, Worldia has always kept pace with market trends, focused on customers’ core needs, and taken solving customers’ machining challenges as its starting point. It strengthens the R&D of custom superhard cutting tools and provides customers with scientific, practical, and reliable machining solutions.
