Problems solved by technology

[0002]At present, the end mills for processing high-strength material workpieces in the prior art are generally made of powder metallurgy high-speed steel materials. This kind of end mills made of powder metallurgy high-speed steel materials Although the end mill has good strength and cutting performance, it has the problem of high production cost
In particular, the existing powder metallurgy high-speed steel materials are mainly imported, so the supply of this material is often lacking in the market, which will undoubtedly affect the production of enterprises
Therefore, the existing method of using powder metallurgy high-speed steel materials to make high-strength end mills is still not ideal.

Embodiment Construction

[0011] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0012] The embodiment of the present invention: the structure of the present invention is shown as figure 1 with figure 2 As shown, when manufacturing an end mill with a cutter head 1 and a cutter shaft 3, the method of the present invention for manufacturing an end mill using a low-cost alloy material is used for manufacturing. When manufacturing, W6Mo5Cr4V2Al is used to replace the existing The powder metallurgy high-speed steel material is used to make the head 1 part of the end mill, and the teeth 2 of the end mill head 1 part are made as follows:

[0013] Ⅰ) Control the rake angle α of the cutter tooth 2 on the end mill head 1 at an angle of 9°~11°;

[0014] Ⅱ) Make the relief angle of the cutter tooth 2 on the end mill head 1 into a structure composed of two relief angles: a first relief angle β1 and a second relief angle β2, and make the width b of the...

Abstract

The invention discloses a method for manufacturing an end milling cutter by using a low-cost alloy material. During manufacturing of the end milling cutter which is provided with a cutter head and a cutter holder, the cutter head part of the end milling cutter is manufactured by using a W6Mo5Cr4V2Al material instead of the conventional powder metallurgy high-speed steel material, and cutter teeth of the cutter head part of the end milling cutter are manufactured by the following steps of: (1) controlling the front angle of each cutter tooth on the cutter head of the end milling cutter at 9-11 degrees; and (II) manufacturing the back angle of each cutter tooth on the cutter head of the end milling cutter into a structure consisting of a first back angle and a second back angle, wherein the width of the first back angle is 0.9-1.2 millimeters, the first back angle is 9-11 degrees, and the second back angle is 18-22 degrees. The method has the advantages of low manufacturing cost, easiness for manufacturing, simple structure and good using effect.

Description

technical field [0001] The invention relates to a method for manufacturing an end mill using low-cost alloy materials, and belongs to the technical field of end mill manufacturing. Background technique [0002] At present, the end mills for processing high-strength material workpieces in the prior art are generally made of powder metallurgy high-speed steel materials. Although the end mills made of powder metallurgy high-speed steel materials have good strength and cutting performance, they are There is a problem that the production cost is high. In particular, the existing powder metallurgy high-speed steel materials are mainly imported, so the supply of such materials is often lacking in the market, which will undoubtedly affect the production of enterprises. Therefore, the existing method of using powder metallurgy high-speed steel materials to make high-strength end mills is still not ideal. Contents of the invention [0003] The purpose of the present invention is t...
