Abstract

The invention provides a high-speed milling tool, comprising: a cutter body, a cutter groove, a cutter holder, a driving screw and an auxiliary pressing screw; the cutter groove is provided with an axial surface of the groove, a radial surface of the groove, A tangential surface and a second tangential surface of the knife groove, the tool holder is provided with an axial surface of the tool holder, a radial surface of the tool holder, a first tangential surface of the tool holder and a second tangential surface of the tool holder; The first tangential surface of the clip and the second tangential surface of the tool holder are arranged opposite to each other and are inclined to form an acute angle a. The tool holder is divided into a fixed part and an elastic part by at least one slit, and the fixed part is provided with a cutting part; The fixing part defines a driving screw hole, and the tool holder moves in the knife groove through the cooperation of the driving screw and the driving screw hole. The invention has reasonable structural design, convenient adjustment, stable tool structure and no flying out under force, and at the same time, the elastic part of the tool holder can provide a similar "damping" effect, reduce the slight vibration of the tool holder during cutting, and improve the life of the tool.

Description

technical field

[0001] The invention relates to the technical field of milling tools, in particular to a high-speed milling tool. Background technique

[0002] With the advancement of cutting technology, milling cutters equipped with welded PCD toolholders are widely used in high-speed milling of aluminum alloys. In order to ensure the life of the tool and the cutting effect, the tool often adopts the following structure, namely: disc-shaped cutter body and set on A cutting unit that can be adjusted axially in the peripheral groove of the cutter body; each cutting unit includes the following structures: cutting tool holder, pressing unit and adjustment unit; in order to ensure the cutting effect of the tool when it is used, such tools are It is necessary to adjust the axial height of each tool holder to ensure the accuracy. The adjustment sequence is: 1. The adjustment unit roughly adjusts the cutting tool holder to the initial predetermined height; 2. The pressing unit pre-...
