English: Composite Milling Requires Dust Control and Sharp Tooling
CNC milling carbon fiber composites requires a different approach from metal cutting. The material is abrasive, layered and sensitive to edge damage. Without proper tool selection and dust extraction, machining can cause delamination, poor edge quality and contamination inside the machine enclosure.
Diamond-coated carbide end mills are often used because carbon fiber wears cutting edges quickly. Tool geometry should shear the fibers cleanly instead of pulling them from the matrix. Vacuum extraction, sealed machining and careful chip-dust management protect both the process and the equipment.
Improving composite edge quality
Use stable clamping, sharp tools and controlled feed. If fibers fray at the edge, review tool wear, cutting direction and support under the laminate. Good dust extraction and low runout help produce cleaner composite parts.
中文：碳纤维复合材料 CNC 铣削的粉尘与边缘控制
碳纤维复合材料 CNC 铣削不同于金属切削。材料具有磨蚀性、层状结构，并且对边缘损伤敏感。如果刀具和除尘不合适，容易出现分层、边缘毛边和机床内部污染。
金刚石涂层硬质合金铣刀常用于碳纤维加工，因为碳纤维会快速磨损普通刃口。刀具几何应尽量剪切纤维，而不是拉扯材料。真空除尘、封闭加工和稳定夹持，有助于提升零件边缘质量。
Français : Usinage CNC des composites carbone
L’usinage des composites carbone demande une aspiration efficace et des outils très résistants à l’usure. Les fraises carbure revêtues diamant aident à limiter l’usure, la délamination et les défauts de bord.
Русский: CNC-обработка углепластика
Углеродные композиты абразивны и чувствительны к расслоению. Для чистой кромки нужны алмазное покрытие инструмента, жесткое крепление, правильная подача и эффективное удаление пыли.
