Abstract

The invention discloses a four-edge milling cutter and a manufacturing method, and belongs to the technical field of woodworking tools. The four-edge milling cutter is formed by grinding and machiningan integral hard alloy, and is provided with four cutting edges, wherein two symmetrical edges are finish milling edges, and the other two edges are provided with chip breaking grooves which are staggered with each other. The arc radius R of each chip breaking groove is R0.8-R1.5mm. The four-edge milling cutter has the advantages that the four cutting edges effectively optimize the chip removal effect and the heat dissipation effect on the basis of ensuring the machining effect, and finally the service life of the milling cutter is prolonged.

Description

technical field [0001] The invention relates to a 4-blade milling cutter and a manufacturing method thereof, belonging to the technical field of woodworking cutters. Background technique [0002] The chip breaking and chip removal effect of the milling cutter in the prior art is poor, and the heat dissipation effect is not good. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a 4-flute milling cutter and a manufacturing method thereof. [0004] A 4-edged milling cutter, which is ground and processed by solid carbide, has 4 cutting edges in total, of which two symmetrical edges are fine milling edges, and the other two edges are provided with mutually staggered chip breakers. [0005] The arc radius R of the chip breaker is R0.8-R1.5mm. [0006] A method for manufacturing a 4-blade milling cutter, comprising the following steps: the 4-blade milling cutter is installed on a fixture, the 4-blade milli...
