Abstract

The invention relates to a machining tool, and particularly relates to a deep-hole drill with a guide block. The deep-hole drill comprises a tool body and a tool handle connected with the tool body, wherein the tool body is cylindrical and comprises a cylindrical bottom surface and a cylindrical side surface; a blade is installed on the cylindrical bottom surface of the tool body; at least one guide block I and two guide blocks II are fixed on the cylindrical side surface of the tool body; the guide block I is close to one end of the tool handle, and the guide blocks II are close to one end of the blade; and the two guide blocks II are distributed in a staggered manner along the circumferential direction of the cylindrical side surface and have the same height in the axis direction of the tool body. The deep-hole drill disclosed by the invention has the characteristics of being simple in structure, good in use effect, long in service life, high in cutting stability, convenient to cool, and the like.

Description

technical field [0001] The invention relates to a machining tool, in particular to a deep hole drill with a guide block. Background technique [0002] In the existing deep hole processing, most of the quality problems are that there are patterns or knives on the surface of the hole wall. The pattern is in a spiral shape. The force of the bar makes the drill bit slightly tilted, resulting in unstable cutting of the outer cutting blade. [0003] A Chinese invention patent named a deep hole drill with publication number CN104400080A, including a base body, a number of blades installed on the end of the base body and a number of guide blocks installed on the outer peripheral surface of the base body. The base body is cylindrical and includes sequentially connected The mounting part, the connecting part and the cutting part are provided with a chip discharge hole along the axis on the base body, and several rows of parallel threaded connecting teeth are provided on the mounting ...
