Abstract

The invention discloses a boring tool used for machining a small-hole-diameter step type round hole inner cavity and provided with a replaceable tool head. The technical problems that when an inner hole inner cavity provided with a step is subjected to high-speed boring machining, the machining concentricity is prone to deviating, and the machining efficiency is low are solved. A tool rod (1) is provided with a barrel-shaped cavity (3), and a cavity opening (4) of the barrel-shaped cavity (3) is connected with a tool head seat (2). The boring tool is characterized in that the tool head seat (2) is provided with a tool head and tool rod connection thread (6) and an annular positioning step (9), and the tool head seat (2) and the tool head and tool rod connection thread (6) are connected into the cavity opening (4); the axis (10) of the annular positioning step (9) coincides with the axis (11) of the tool rod (1); and a tool blade (7) is fixed to the tool head seat (2) through a jackscrew (8). The machining efficiency and the machining quality are greatly improved.

Description

technical field [0001] The invention relates to a circular inner cavity boring tool for a metal piece, in particular to a circular inner cavity boring tool with a small diameter and a step on the inner side wall. Background technique [0002] Boring is a cutting process that uses tools to enlarge the inner diameter of a hole or other circular inner contours. The application range covers from semi-rough cutting to fine cutting; Cutting tool, a metal cutting processing method for hole reaming; in the process of high-speed boring processing, the tool speed is fast and the feed rate is also large. High-speed boring can save 30% machining time, and the feed rate is 5 to 10 times that of traditional cutting. It has the characteristics of small cutting force, and can machine thin-walled parts, greatly improving its surface finish. . In the boring process, sometimes there are steps or even multiple steps on the side wall of the inner cavity in the inner hole of some products. Afte...
