Abstract

The invention discloses a turning insert with multiple feeding directions. A set of acute-angled diagonal positions of the insert body form an acute-angle cutting unit. The acute-angle cutting unit includes an angle cutting edge group and two core cutting edges. , the corner cutting edge group and the core cutting edge are kept away from the workpiece in turn. The corner cutting edge group includes two corner cutting edges and an outer corner cutting edge located between the two corner cutting edges. The corner cutting edge is adjacent to the core cutting edge on the same side. Set, in the direction of the upper surface, the angle Ξ² between the two corner cutting edges in any acute-angle cutting unit is greater than the angle β’ between the two core cutting edges in the acute-angle cutting unit, in the direction of the side , the corner cutting edge is inclined from the outer corner cutting edge to the inner side of the upper surface and the angle between the upper surface and the upper surface is Ξ±, and satisfies: 5°≀α≀15Β°, the turning insert with multiple feed directions of the present invention has good strength, It has the advantages of high cutting efficiency and good surface processing quality.

Description

technical field

[0001] The invention relates to the field of metal cutting, in particular to a turning insert with multiple feeding directions. Background technique

[0002] Usually, in turning, turning inserts with a rhombus and other parallelograms with an acute angle of 35Β° have relatively sharp cutting edges. , can effectively reduce the feed interference of the workpiece, and has multiple feed directions to have a larger processing space. It is widely used in cylindrical processing, end face and root cleaning, etc. turning. Although this type of insert has sharp cutting and multiple feed directions, the roughness of the machined surface is not ideal due to the small cutting angle, and the cutting unit strength is low due to the small included angle. In order to ensure stable turning, the cutting depth and cutting feed are both limited Larger limit, low cutting efficiency. Contents of the invention
