Problems solved by technology

[0003] This application is to solve the existing problems. With the rapid development of modern metal processing industry technology, industrial sectors such as machinery manufacturing, electromechanical, weapons and aviation have introduced many high-strength, high-hardness new materials such as high-strength, ultra-high-strength steel, Stainless steel, titanium alloy, chilled cast iron and other difficult-to-machine materials, due to their high strength, high hardness and high strain hardening rate, make it more difficult to process, and the cutting force is large, the temperature rises during processing, and the tool wear is serious. For the technical problems of poor surface quality and low metal removal rate, provide milling cutters, ultrasonic electric spark milling equipment and milling methods

Abstract

The invention discloses a milling cutter. The milling cutter comprises a cutter body, a cutter blade and a discharge electrode arranged on the cutter body, wherein the cutter body comprises a cutter bar and a cutterhead arranged at one end of the cutter bar, a first fixing part and a second fixing part are arranged in the peripheral direction of the cutterhead in a bulging manner at an interval, the cutter blade is arranged at the first fixing part, the discharge electrode is arranged at the second fixing part, the maximum distance D1 between a position of the cutter blade and a cutterhead rotating shaft is larger than the maximum distance D2 between a position of the discharge electrode and the cutterhead rotating shaft, and the maximum height H1 between the cutterhead and the end, away from the cutterhead, of the cutter blade is larger than the maximum height H2 between the cutterhead and the end, away from the cutterhead, of a position of the discharge electrode. The discharge electrode electrically breaks down a dielectric medium between the discharge electrode and a metal part to produce high temperature, characteristics of a to-be-processed surface change, the surface of themetal part is softened, a free-cutting denatured layer is produced, and finally, the denatured layer and a thin substrate are cut off by the cutter blade.
