Abstract

The invention relates to an efficient PCD-formed drilling reamer which comprises a reamer handle and a reamer head, wherein a cavity is formed in the reamer handle and the reamer head; a first pin rod and a second pin rod are arranged in the cavity; the reamer head comprises a primary reamer head and a secondary reamer head; a first reamer blade and a second reamer blade are arranged at the top of the primary reamer head; the first reamer blade is of a fan-shaped structure; a first PCD blade is arranged on one side of the first reamer blade; a first groove is formed between the other side of the first reamer blade and the primary reamer head; a third reamer blade and a fourth reamer blade are arranged at the top of the secondary reamer head; the edge of the third reamer blade is arc-shaped; a second PCD blade is arranged on one side of the third reamer blade; a second groove is formed between the other side of the third reamer blade and the secondary reamer head; and the second groove communicates with the first groove. The efficient PCD-formed drilling reamer provided by the invention is high in abrasion resistance and has the advantages that different sizes of steps in the same hole can be machined, the machining efficiency can be improved, and the service life can be prolonged.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a high-efficiency PCD forming drill reamer. Background technique [0002] PCD (polycrystalline diamond) is a kind of cemented carbide. Diamond tools have extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient, and low affinity with non-ferrous metals, etc. advantage. [0003] PCD milling cutter is used to ream the drilled hole on the workpiece, mainly to improve the machining accuracy of the hole and reduce its surface roughness. It is a tool for finishing and semi-finishing the hole. The machining allowance Usually very small. However, traditional milling cutters are not equipped with carbide guide strips for processing, which reduces the stability of reaming processing and the accuracy of product coaxiality processing, and traditional milling cutters cannot simultaneously process different size...
