Novel reamer

Abstract

The invention relates to a novel reamer which comprises a reamer handle used in cooperation with a machine tool spindle, and a tail flat part arranged on the end face of one end of the reamer handle and used for clamping a reamer changing mechanical arm; the novel reamer further comprises a reamer body arranged at the other end of the reamer handle, and the reamer body comprises a cutting edge and two guide blocks which are arranged on the side face of the reamer body; and a chip containing groove is formed in the position, on one side of the cutting edge, of the end portion of the reamer body, a central water outlet hole is further formed in the reamer body, and a water outlet of the central water outlet hole is formed in the chip containing groove. According to the novel reamer, the phenomenon that a traditional reamer deflects along a bottom hole is avoided in the reaming procedure machining process, the size precision and roughness value of a reamed hole are better, and the rough reaming procedure and the fine reaming procedure of hole reaming can be combined into one.

Description

technical field [0001] The invention relates to a novel reamer, which belongs to the technical field of parts processing. Background technique [0002] When using a common machine reamer for the reaming process, the twist drill is generally used first to process the bottom hole, and then the reamer is used for rough and fine reaming of the hole. If the bottom hole is skewed, the reamer will also be deflected along the direction of the bottom hole, which will affect the processing quality of the part. Generally used reamers are multi-bladed. Although the efficiency of multi-bladed cutting is high, in superfinishing, due to the large number of cutting blades, multiple cutting forces will be generated, which will inevitably affect the machining vibration. Stability will be more prominent. [0003] In addition, the processing resistance of multi-blade cutting is relatively large, and the resistance will push the reamer to deviate from its processing route, causing the reamed h...
