English: Thread Milling Adds Flexibility to CNC Machining
CNC thread milling uses a rotating carbide thread mill and circular interpolation to create internal or external threads. Compared with tapping, thread milling can offer better control in blind holes, large threads and difficult materials. If a thread mill breaks, it is often easier to remove than a broken tap, which can reduce scrap risk on high-value parts.
A carbide thread mill can machine different thread diameters with the same pitch, depending on tool size and program strategy. This flexibility is useful for low-volume parts, repair work and components with expensive material. The process also creates smaller chips, which helps in deep or blind threaded holes.
Programming and quality checks
Accurate pitch, thread depth and toolpath compensation are essential. Operators should inspect thread fit with proper gauges and confirm that the toolpath direction matches the desired thread hand. Stable machine interpolation improves thread surface quality and repeatability.
中文：什么时候选择 CNC 螺纹铣削而不是攻丝
CNC 螺纹铣削通过硬质合金螺纹铣刀和圆弧插补加工内螺纹或外螺纹。相比攻丝，螺纹铣削在盲孔、大规格螺纹和难加工材料中更灵活。如果刀具折断，螺纹铣刀通常比丝锥更容易处理，可以降低高价值零件报废风险。
同一螺距的螺纹铣刀可以加工不同直径范围的螺纹，适合小批量、多规格和维修类加工。螺纹铣削产生的切屑更小，对深孔和盲孔排屑也更友好。
Français : Fraisage de filets CNC
Le fraisage de filets utilise une fraise carbure et une interpolation circulaire. Cette méthode offre plus de flexibilité que le taraudage pour les trous borgnes, les grands filetages et les matériaux difficiles. Le contrôle du pas et la compensation outil sont essentiels.
Русский: Резьбофрезерование на CNC
Резьбофрезерование выполняется твердосплавной резьбовой фрезой по круговой интерполяции. Метод удобен для глухих отверстий, крупных резьб и сложных материалов, а также снижает риск брака при поломке инструмента.
