Embodiment Construction

[0023] The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 The shown corrugated spiral milling cutter for finishing aerospace materials includes a blade 100 for cutting and a handle 200 for clamping. Specifically, the blade 100 is made of polycrystalline diamond material, and the handle 200 is made of hard alloy, the blade 100 is connected to one end of the handle 200 by high-frequency induction welding to form an integral body, and the blade 100 is made of polycrystalline diamond, which has higher hardness, better wear resistance and durability than cemented carbide. High characteristics, when processing high-hardness materials such as carbon fiber materials, there will be no rapid wear of the tool due to the high hardness of the workpiece during the processing, and then problems such as delamination, tearing and burrs in the processing of the workpiece.

Abstract

The invention provides a corrugated spiral milling cutter for precise machining of an aerospace material, which comprises a blade part for cutting and a handle part for clamping, wherein the blade part comprises peripheral blades and end blades, chip discharging grooves are uniformly distributed between the peripheral blades, chip containing grooves are uniformly distributed between the end blades, each chip containing groove is communicated with one chip discharging groove, and the cutting edge of each peripheral blade is in an circular arc wave shape. The corrugated spiral milling cutter for precise machining of the aerospace material has the following beneficial effects that through the circular-arc-wave-shaped cutting edges of the peripheral edges, the technical problem that when an existing cutter is used for precise machining of the aerospace materials, the roughness and the machining precision are poor is solved; and the corrugated spiral milling cutter for precise machining of the aerospace material can achieve precise machining of materials such as aerospace composite materials, carbon fiber materials, titanium alloys and nickel-based alloys.

Description

technical field [0001] The invention relates to the technical field of milling cutters, in particular to a corrugated spiral milling cutter for finishing aerospace materials. Background technique [0002] Since the 20th century, with the rapid development of my country's aerospace industry, materials such as carbon fiber composite materials, carbon / epoxy composite materials, high-temperature titanium alloys, and high-temperature nickel-based alloys have been widely used in the aerospace field due to their advantages. The application has also led to the difficulty of finishing machining, which is prone to phenomena such as large cutting resistance of the tool, easy tool vibration, chip sticking, and severe tool wear, which has become one of the problems that plague people in the processing of aerospace materials. [0003] When traditional cemented carbide milling cutters process materials such as titanium alloy and carbon fiber, due to the low thermal conductivity of titanium ...
