The tool electrode comprises a discharge electrode (1), a supporting disk (2), a discharge electrode compression gasket (3), a disk charge electrode compression nut (4), a tool electrode shaft (5), a screw (6), a grinding bar compression nut (7), a grinding bar compression gasket (8) and a grinding bar (9). when in processing, the tool electrode compositely processed by the electric spark end face milling and the mechanical grinding is arranged on a main shaft head of a machine tool, and performs the rotation motion and the movement in Z direction under the drive of the main shaft head; the tool electrode and a workpiece arerespectively connected with the cathode and the anode of a pulse power source, operating fluid is poured between the tool electrode and the workpiece; and the tool electrode is subject to the electricspark milling by the discharge action generated between the end face of the discharge electrode (1) and the workpiece and the mechanical grinding by the grinding action between the end face of the grinding bar (9) and the workpiece.

Description

technical field [0001] The invention belongs to the field of special processing, and relates to an electrode of an electric spark end face milling and mechanical grinding compound processing tool. Background technique [0002] Electric discharge milling is a new type of processing technology that began to be studied in the late 1980s and developed in the early 1990s. It uses a simple-shaped electrode (such as a rod-shaped electrode) to move along a certain trajectory like a milling cutter. Under the control of a numerical control system, the electrode can perform EDM milling on a three-dimensional cavity or surface. Compared with traditional EDM, EDM not only saves the design and manufacture of forming electrodes, shortens the production cycle of products, reduces processing costs, improves processing flexibility, but also effectively improves processing stability , Reducing the capacitive effect is a processing technology with great development prospects. At present, the ...
