Problems solved by technology

[0004] 1. During the blisk machining process, the surface structure of the blade is complex, the direction of the tool axis is constantly changing, the wear degree of the ball cutter is large during the machining process, and the machining life is low;
[0005] 2. Ordinary ball cutters have poor chip removal ability, easy to break the cutter, and low processing efficiency;
[0006] 3. When the ball cutter is processing the surface of the blisk, the rebound of the blisk surface to the ball cutter will increase, so the area in contact with the ball cutter will increase, and the machining accuracy will decrease.

Abstract

The invention discloses a heat-resistant alloy high-efficiency milling cutter and solves the problems of easy chip removal and cutter breaking, short service life, low processing efficiency and the like of a conventional ball cutter during rough machining of a blade disc. According to the technical scheme, the heat-resistant alloy high-efficiency milling cutter is characterized by comprising a cutter bar, wherein a cutter head is formed at one end of the cutter bar; a central boss is formed on the cutter head; cutting edges and a chip groove are formed in the cutter head; the central boss is fixedly connected with the center of the cutter bar; the central boss and the cutter bar are coaxially arranged; the number of the cutting edges is at least four; the cutting edges are evenly distributed on the side periphery of the central boss and circumferentially arranged with the central boss as the center; the chip groove is formed between the two cutting edges; the top of the central boss serves as a base face; every two cutting edges, symmetrical about the central axis of the central boss, on the base face are in an S shape; the cutting edges and the chip groove extend to the side body of the cutter bar in the same spiral direction; and the cutting edges and the cutter bar are connected into a whole.

Description

technical field [0001] The invention relates to the technical field of cutters, more specifically, it relates to a heat-resistant alloy high-efficiency milling cutter. Background technique [0002] In the rough machining of titanium alloy blisks in the field of aero-engines, the blisks are generally made of titanium alloys or high-temperature alloys, which are directly processed through traditional processing, so there are a large number of rough machining links in the early stage, and the overall structure of the blisks is complex. , The blade has a large twist, and the ball cutter is often used for side milling during processing. [0003] However, ordinary ball cutters have the following problems when processing blisks: [0004] 1. During the blisk machining process, the surface structure of the blade is complex, the direction of the tool axis is constantly changing, the wear degree of the ball cutter is large during the machining process, and the machining life is low; ...
