  • Diamond Drilling of Carbon Fiber Reinforced

    One of the first factors that comes up in any consideration of tooling for composite machining is the material’s abrasive nature. Particularly with carbon fiber composites, there’s no chip making. Instead, the cutting edge shatters the material and the carbon fibers. It is this process that makes machining carbon fiber so abrasive to the tool.
