Abstract

The invention provides a high-speed milling tool which comprises a tool body, tool grooves, a tool clamp, a driving screw and auxiliary pressing screws. Each tool groove is provided with a tool grooveaxial surface, a tool groove radial surface, a tool groove first tangential surface and a tool groove second tangential surface. The tool clamp is provided with a tool clamp axial surface, a tool clamp radial surface, a tool clamp first tangential surface and a tool clamp second tangential surface. The tool clamp first tangential surface and the tool clamp second tangential surface are oppositelydisposed and tilted to each other at an acute angle a. The tool clamp is divided by at least one seam into a fixed part and an elastic part. The fixed part is provided with a cutting part. A drivingscrew hole is formed in the fixed part. The tool clamp moves in the tool grooves when the driving screw is matched with the driving screw hole. The high-speed milling tool is reasonable in structuraldesign, convenient to adjust and stable in structure and cannot fly out under force, meanwhile the elastic part of the tool clamp can provide a similar 'damping' effect, microvibration of the tool clamp during cutting is reduced, and the service life of the tool is prolonged.

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-...
