Abstract
The invention provides a flat-end three-edge PCD (Poly Crystal Diamond) milling cutter. The flat-end three-edge PCD milling cutter is characterized by comprising a handle and a head end, wherein a guide fixing hole is formed in one end of the handle; the head end comprises a head, a connecting rod and a guide fixing rod; the handle and the head end are integrally connected by the engaging of inner threads and outer threads. The flat-end three-edge PCD milling cutter is simple in structure and reasonable in design; the milling cutter can be divided into two detachable parts. The milling cutter is different from an integral milling cutter in that the handle and the head end are detachable, namely, the head end can be simply replaced in case that the head is worn or broken, and the handle is not displaced, so that the production cost can be saved; meanwhile, the handle and the head end are integrally connected by the engaging of the inner threads and the outer threads; one end surface of the handle and the corresponding opposite end surface of the connecting rod are closely bound together, thus the handle and the connecting rod can be stably connected, and the cutting effect of the milling cutter cannot be influenced; in addition, blades are manufactured from PCD materials, so that the milling cutter has the characteristics of being high in hardness, high in pressure resistance, high in heat transfer property and high in wearability.
