A fast-feed milling insert and its milling tool

Abstract

The invention discloses a fast-feed milling insert and a milling tool thereof. The milling insert comprises a substantially quadrangular insert body; the insert body has an upper surface, a bottom surface and side surfaces; The adjacent main cutting edges are transitioned by rounded corners at the corners of the insert body to form a tip, and the tip has a rounded cutting edge; the upper surface of the insert body extends from the cutting edge to the center. The rake face, the concave curved surface and the positioning surface, in the concave curved surface, there are a plurality of reinforcing ribs corresponding to the four sides of the blade body, and in the counterclockwise direction from the tool tip to the main cutting edge, the adjacent The distribution of the distance between the ribs varies from small to large. The present invention can rationally allocate the chip-holding space of the cutting tool under different cutting depths, simultaneously enhance the ability of the cutting tool to lock the cutting fluid, reduce the temperature rise of the cutting tool, increase the strength of the cutting edge, and improve the chipping resistance of the cutting blade.

Description

A kind of fast feed milling insert and its milling cutter technical field [0001] The present invention relates to the technical field of tools, in particular to a fast-feed milling insert and a milling tool therefor. Background technique Milling tool is a tool used for cutting in mechanical manufacturing, because the tool used in mechanical manufacturing is basically They are all used for milling metal materials, so these tools are metal cutting tools. With the development of processing and manufacturing technology, rough machining The need for efficiency in milling is increasing day by day, therefore, fast feed milling inserts with high metal removal rates are used in aerospace, automotive It is widely used in processing industries such as tools. Prior art fast feed milling inserts are mounted on a shank having an axis of rotation On the other hand, the machining method of small depth of cut and high feed rate is usually adopted, but the high-feed milling inserts ...

AI Technical Summary

Problems solved by technology

[0003] 1. When there is a need to increase the cutting depth during the machining process, the chip space is insufficient and the heat dissipation of the tool is poor;

[0004] 2. Insufficient chip removal ability when processing high plastic materials;

[0005] 3. In the process of high-speed machining, the tool temperature rises too fast, and the ability to lock the cutting fluid is insufficient
