Problems solved by technology

However, in the processing of titanium alloy or some other hard metals, the above two kinds of cutting tools cannot overcome the above problems well, so that continuous processing cannot be carried out for a long time, and the tool life is short, resulting in low productivity and low yield.

Embodiment Construction

[0022] A schematic solution of the milling cutter of the present invention will now be described with reference to the following specific embodiments in conjunction with the accompanying drawings. Although the drawings are provided to illustrate some embodiments of the invention, the drawings are not necessarily to scale and certain features may be enlarged, removed, or sectioned to better illustrate the invention.

[0023] In addition, unless otherwise specified, certain directional terms in the present invention shall be based on the understanding of those skilled in the art. For example, the "front" and "rear" positions in the components of the milling cutter are determined according to the direction of rotation of the milling cutter. In addition, regarding the definition of "axial", "radial" and "circumferential", it is generally considered that the extension direction of the central axis of the milling cutter is the axial direction, and the direction passing through the a...

Abstract

The invention provides a milling cutter which is used for processing a forming surface and can rotate around a central axis. The milling cutter comprises a rigid cutter body (1), polycrystalline diamond blades (2) respectively fixed on tooth bases as well as a cooling structure, wherein the cutter body is provided with at least two tooth bases (10) which are parallelly arranged at an interval; the polycrystalline diamond blades (2) can axially extend and can exceed the tail end of the rigid cutter body (1) so as to form end teeth (4), and the outmost radial sides of the polycrystalline diamond blades can limit circumference teeth (3); the cooling structure comprises a main cooling channel (3) formed in the cutter body and cooling holes (6,8) which are communicated with the main cooling channel (3) and can supply a cooling fluid to the blades (2).

Description

technical field [0001] The invention relates to a polycrystalline diamond milling cutter for processing a forming surface, in particular to a polycrystalline diamond milling cutter for processing titanium alloy. Background technique [0002] Titanium alloy is a new type of material commonly used in modern aviation and aerospace. It is light in weight, high in hardness, high in toughness, good in corrosion resistance, poor in thermal conductivity (generally only 1 / 5 of iron and 1 / 3 of aluminum), and has a large friction coefficient ( approximately 0.42). Because of this, in the processing of titanium alloys, such as cutting, it is easy to increase the temperature of titanium alloy workpieces and tools, resulting in sticking of the knife and reducing the life of the tool. big difficulty. [0003] A milling cutter is a tool used to process a workpiece forming surface such as a metal surface or other surface. In production, the cylindrical milling cutter is usually used to pr...
