Problems solved by technology

In the existing hole processing technology, boring is generally divided into rough boring and fine boring, that is, rough boring is carried out on the part to be processed first, and then fine boring is carried out after leaving a margin. However, the existing multi-edged boring tools are generally integrated structure, suitable for rough boring, and fine boring tools are generally single-edged tools, that is, different boring tools need to be used for rough boring and fine boring. time, inefficiency

Abstract

The invention discloses a rough-finish multi-blade boring tool comprising a tool body (1), rough boring blades (5) and finish boring blades (4). The tool body (1) at least comprises two radial projections (2). At least one radial projection (2) is provided with one finish boring blade (4), and an open slot (3) forms at the junction of each radial projection and the tool body (1). Each radial projection (2) with one open slot (3) is provided with a threaded through hole (8) which fits an adjusting screw (6). Each rough boring blade (5) is mounted on the corresponding radial projection (2) with no open slot (3) through a screw (7). Each finish boring blade (4) is mounted on the corresponding radial projection (2) with one open slot (3) through another screw (7). Horizontal plane of the finish boring blades (4) is lower than the horizontal plane of the rough boring blades (5). The rough-finish multi-blade boring tool is available for simultaneous completion of rough boring and finish boring, so that work time is reduced and work efficiency is improved.

Description

technical field [0001] The invention relates to a cutting tool used in machining, in particular to a rough-finish compound multi-edged boring tool. Background technique [0002] Boring tools are commonly used in inner hole machining, and are generally divided into single-edged boring tools and multi-edged boring tools. When machining larger holes, multi-edged boring tools are generally used to improve machining efficiency. In the existing hole processing technology, boring is generally divided into rough boring and fine boring, that is, rough boring is carried out on the part to be processed first, and then fine boring is carried out after leaving a margin. However, the existing multi-edged boring tools are generally integrated structure, suitable for rough boring, and fine boring tools are generally single-edged tools, that is, different boring tools need to be used for rough boring and fine boring. Time, work efficiency is low. Contents of the invention [0003] The t...
