The three-axis vertical machining center, as the core equipment of modern manufacturing, achieves integrated processing capabilities that are multifunctional, high precision, and high efficiency through the synergy of a high-rigidity structure and an intelligent CNC system: its 3D milling function can perform machining on flat surfaces, curved surfaces, and complex cavities (such as mold cores); precision hole processing includes drilling, boring, and reaming; thread forming supports tapping and non-standard thread milling, conforming to ISO 6H/6g precision standards; special processing includes chamfering, counterboring, T-slots, and inclined surface milling (requiring a fourth axis).
