Precise reaming reamer

Abstract

The invention discloses a precise reaming reamer, and relates to the technical field of reamers. The reamer comprises a reamer head, a reamer handle and an edge part; a cylindrical guiding section which is coaxial with the reamer handle is formed in the reamer handle; the diameter of the cylindrical guiding section is larger than that of the reamer handle, and is smaller than a nominal diameter ofthe reamer head; the edge part is integrally moulded on one end, which is far away from the reamer head, of the reamer handle; besides, the edge part comprises bottom edges located at the tail end ofthe edge part and side edges which are wound on the side surface of the edge part; the angles of the bottom edges distributing or extending toward a geometrical center are minus; slag accommodation grooves are formed between the bottom edges and bottom edge backs which extend toward the side edges; the bottom edges extend toward the side edges and are integrally connected to the side edges; a slag discharging groove with a waved shape is formed by every two adjacent side edges; and each slag discharging groove is connected to the tail end f the corresponding slag accommodation groove.

Description

technical field [0001] The invention relates to the technical field of milling cutters, in particular to a reamer with precise reaming. Background technique [0002] Milling cutters are generally specially designed and manufactured for machining workpieces with specific shapes. They are usually used for machining angled surfaces, groove surfaces, special-shaped holes and stepped surfaces, etc. The cutting edge shape of milling cutters generally matches the shape of the workpiece. In order to form the required specific shape on the workpiece through one-time processing, but after using traditional milling cutters, the product is easily deformed. [0003] At the same time, for deep holes, in order to meet deep hole processing, the shank adopts a long rod structure. Because the tool shank is too long, the ability to transmit torque is reduced, and it is easy to deform under the action of torque, which cannot guarantee the size and shape accuracy of deep hole processing. , resu...

[0002] Milling cutters are generally specially designed and manufactured for machining workpieces with specific shapes. They are usually used to process angled surfaces, groove surfaces, special-shaped holes and stepped surfaces, etc. The cutting edge shape of milling cutters generally matches the shape of the workpiece. In order to form the desired specific shape on the workpiece through one-time processing, but after using traditional milling cutters, the product is easily deformed

[0003] At the same time, for deep holes, in order to meet deep hole processing, the shank adopts a long rod structure. Because the tool shank is too long, the ability to transmit torque is reduced, and it is easy to deform under the action of torque, which cannot guarantee the size and shape accuracy of deep hole processing. , causing unqualified products and increasing the scrap rate
