Embodiment Construction

[0039] exist figure 1 In, the first embodiment of the present invention discloses the electrical discharge machining process. Wherein, the composite material electrode 130 is in the shape of a circular tube, and its electrical discharge machining surface has protruding insulating abrasive particles 131. When performing electrical discharge machining, the composite material electrode 130 approaches the machining surface 210 through the servo mechanism of the electrical discharge machining machine. When the spacing is too small, the insulation between the composite material electrode 130 and the machined surface 210 will collapse and a transient arcing phenomenon will occur. The resulting energy will act on the machined surface 210, causing it to melt to form a machined indentation, and most of the molten material will form bumps on the surrounding surface of the indentation. At the same time, the composite material electrode 130 is used to grind the processed surface, and the ...

Abstract

The invention discloses a composite material electrode for electric discharge machining and the preparation method. The electric discharge machining surface for the composite material electrode comprises a bulgy hard insulating grinding particle. In the process of electric discharge machining, the bulge around the indent is removed by grinding. The processing method includes the following steps: sintering the metal powder and the nonconducting and fire-resistant grinding particles in a manner of powder metallurgy, making the insulating grinding particles higher than the electric discharge machining surface by corrosion.

Description

technical field [0001] The invention belongs to the field of electrical discharge machining, and in particular relates to a composite material electrode applied to electrical discharge machining and a manufacturing method thereof. Background technique [0002] With the advancement of the machinery industry, the requirements for materials are gradually increasing. Therefore, the design of mechanical components often requires the use of materials with high hardness, high strength, good heat resistance and corrosion resistance to meet the requirements of some special occasions and environments. This result often leads to an increase in the difficulty of component processing. Electrical discharge machining (Electrical Discharge Machining) technology can be applied to the machining of superhard alloys and die steel and other materials. It can not only effectively process hard materials with complex shapes, but also achieve precise machining effects. [0003] In order to achieve ...
