高速铣削日益成为模具半精加工、精加工的主流工艺手段,与EDM相比有如下特点:■除有内锐角的型腔和极窄而深的型腔外均可采用。■加工模具型面可比EDM加工节省25%～60%加工工时。■型面表面质量好,可避免EDM加工可能出现的表面微细型纹。■高速铣削能加工45～60HRC硬表面,精铣面粗糙度可达Ra0.63,减少手工抛光工时。■省却EDM加工电极的制造环节,显著缩短制模周期。 High-speed milling is increasingly becoming the dominant tool for semi-finishing and finishing machining. Compared with EDM, it has the following features: ■ Except for acute-angled cavities and very narrow and deep cavities, it can be used. ■ Machining die surface can save 25% ~ 60% of EDM processing time. ■ good surface quality of the surface, to avoid EDM processing may appear on the surface of fine lines. ■ High-speed milling 45 ~ 60HRC hard surface can be processed, precision finishing surface roughness Ra0.63, reducing manual polishing hours. ■ save the EDM processing electrode manufacturing processes, significantly shortening the molding cycle.
