Efficient drum-shaped profiling end mill

Abstract

The invention discloses an efficient drum-shaped profiling end mill. The efficient drum-shaped profiling end mill comprises a cutting part and a handle part, wherein the cutting part is provided witha plurality of chip grooves which spirally extend from the bottom end to the handle part; the surface, facing the cutting rotation direction, of each chip groove is a front cutter surface; the front cutter surfaces and the peripheral surface of the cutting part are intersected to form cutting edges; the cutting edges are wave-shaped cutting edges by machining the front cutter surfaces, and are divided into circumferential cutting edges and ball head cutting edges; the outlines of the circumferential cutting edges are two sections of symmetrical arcs; the bottom end cutting edges are the ball head cutting edges; included angles of the edges are unequal; the surface, connected with the cutting edges, in the peripheral surface of the cutting part is a first rear cutter surface; the first rearcutter surface extends from the bottom end of the cutting part to the handle part; chip breaking grooves are spirally distributed in the first rear cutter surface. The efficient drum-shaped profilingend mill has the advantages that the semi-finish machining and finish machining efficiency of a workpiece can be greatly improved, a narrow workpiece can be machined, the strength is high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a high-efficiency drum-shaped profiling end mill. Background technique [0002] In the metal processing industry, especially in the process of blisk machining, the curved surface of the blade is usually a ruled surface or a free-form surface. The general processing strategy is to use the traditional ball nose cutter for semi-finishing or finishing the blade surface, but the ball head The tool is limited by the tool shape, the actual cutting amount is small, and the processing efficiency is low. If the radius of the ball head arc is increased, it is easy to have large chips and poor chip breaking. Moreover, in the narrow processing space, the tool path It is also easy to be restricted. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a high-efficiency drum-shaped profiling end mill, which ...
