Self-repairing tool electrode turning type discharging processing device and method

Abstract

The invention discloses a self-repairing tool electrode turning type discharging processing device and method. The self-repairing tool electrode turning type discharging processing device mainly comprises a tool electrode and a metal block, wherein the tool electrode comprises a metal base body and an abrasive particle layer fixedly bonded on the surface of the metal base body through a conducting abrasive particle bonding agent; the tool electrode and a workpiece can rotate around a self axial line; the tool electrode can approach to or leave away from the workpiece along a direction vertical to the axial line of the workpiece; the metal block is tightly pressed on the abrasive particle layer of the tool electrode. In the use process, the rotating tool electrode grinds the metal block; generated chippings are adhered on the abrasive particle layer of the tool electrode, so that a metal adhesion layer is formed; the discharging processing is performed by using the adhesion layer; the adhesion layer loss can be caused by a spark effect in the processing process; then, the adhesion layer with loss grinds the metal block again through the tool electrode to be supplemented and rebuilt, so that the geometrical shape of the tool electrode is recovered in time; the service life of the tool electrode is unquestionably prolonged; the processing precision is improved; the processing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of machining equipment, in particular to a self-repairing tool electrode turning electric discharge machining device and method. Background technique [0002] Shaft (or sleeve) parts are the most common key parts in mechanical products, and their machining accuracy and surface quality directly affect the performance of the product. Most of the rotating surfaces of these parts are processed by turning. [0003] The traditional turning process is to use a higher hardness object as a tool to cut a softer object, and remove the excess material on the surface of the workpiece to be processed by extrusion, so that the workpiece can reach the specified geometric shape, dimensional accuracy and surface quality processing methods. With the development of science and technology, materials with excellent performance are used in many advanced equipment, such as high-temperature alloys, stainless steel, titanium alloys...
