Challenges in Machining Composite Materials

Composite materials, such as carbon fiber reinforced polymer (CFRP), glass fiber reinforced polymer (GFRP) and phenalic, consist of a combination of different substances that possess diverse chemical and physical characteristics. These materials find extensive use in various applications, prioritizing the reduction of weight and enhancement of strength.

When machining composites, cutting tools face challenges due to the highly abrasive properties and relatively low melting point of the material. To ensure the production of exceptional composites end products, it is crucial to use specially designed diamond coated carbide tools or PCD tooling created specifically for the material.

Kennametal has mastered navigating the challenges of composites machining by providing consistent material surface finishes and increasing material removal rates with innovative cutting tool solutions that uncomplicate composites and take your projects to the next level.

Explore some of our top machining solutions below to make your composites operations a cut above the rest.
