Abstract

This utility model discloses a milling insert with a variable cutting mode, relating to the field of metal cutting technology. Specifically, it is a milling insert with a variable cutting mode, including an insert and a cutter head. The insert consists of a cutter body, a flank face, a first flank face connecting arc, a second flank face connecting arc, an end face, a square shoulder rake face, and a high feed rake face. This milling insert with a variable cutting mode can combine two types of inserts into one insert. For different cutting mode requirements in machining, a high feed or square shoulder cutter head can be selected accordingly. The insert no longer needs to be distinguished by type like conventional products; only one insert is needed to correspond to different types of cutter heads. Moreover, the insert is designed to be used on both sides, and each corner has two cutting edges, a high feed edge and a square shoulder edge, for a total of 12 cutting edges. It has good economic efficiency and also solves the waste of resources in insert manufacturing. For the users of the insert, the cost is significantly reduced.
