Problems solved by technology

[0002] Modern large-scale generator rotor oxygen-free copper bar molding processing, low roughness value, no burrs, high shape accuracy, requires high speed, high precision, and high life, because ordinary tools have poor accuracy, short life, and low speed
Obviously, it does not meet the basic requirements of high speed, high precision, high stability, high efficiency and long life of the modern processing industry, so it is necessary to study tool materials, tool parameters, cutting parameters, metal rheological friction and wear principles, and develop special concave molding PCD fishtail cutter to accomplish this

Embodiment Construction

[0021] Such as Figure 1 to Figure 4 As shown, in order to achieve the stated purpose, the PCD fishtail milling cutter of the present invention is formed by the relative combination of the mirror surface of the left knife 1 and the right knife 2, and the left knife 1 and the right knife 2 can be relatively rotatably arranged (for example, the co-rotating axis setting) to adjust the distribution angle of the PCD teeth 11 to 14, 21 to 24 on the circumference. The left knife 1 and the right knife 2 are made separately.

[0022] exist Figure 1 to Figure 4 In the shown embodiment, each specific dimension of the tool is marked in detail according to national standards, and the unit of each length dimension in the figure is mm.

[0023] The left knife 1 and the right knife 2 are generally composed of mirror images, but if there is system resonance, the left knife 1 and the right knife 2 rotate about 5° relative to each other; if it is necessary to strengthen chip breaking, the lef...

Abstract

The invention relates to a PCD (polycrystalline diamond) fishtail cutter which aims at solving the problems of oxygen-free copper molding milling, high speed, high accuracy, high stability, no burrs and long service life. The PCD fishtail cutter is characterized by being formed by combining a left cutter image and a right cutter image oppositely, and a left cutter and a right cutter are arranged in an oppositely rotating way to regulate the distribution angle of PCD cutter teeth.

Description

technical field [0001] The present invention relates to a high-speed precision cutting tool, in particular to a concave forming milling cutter, which is used in a one-time forming process, and can perform high-speed, high-precision, long-life cutting, and is particularly effective in forming and milling oxygen-free copper row edges of large generators. , low roughness value, no burrs. Background technique [0002] Modern large-scale generator rotor oxygen-free copper bar molding processing, low roughness value, no burrs, high shape accuracy, requires high speed, high precision, and high life, because ordinary tools have poor precision, short life, and low speed. Obviously, it does not meet the basic requirements of high speed, high precision, high stability, high efficiency and long life of the modern processing industry, so it is necessary to study tool materials, tool parameters, cutting parameters, metal rheological friction and wear principles, and develop special concav...
