Embodiment Construction

[0018] like figure 1 As shown, the electrode device 1 includes an electrode 10, a power source 11 and a machining fluid source (not shown). The electrode 10 is disposed within a bore 14 of a conductive workpiece 12 and includes a tubular element 16 and a conductive element 18 received within the tubular element 16 . The tubular element 16 is provided with an upper surface 160 , a bottom surface 162 and a side 164 between the upper surface 160 and the bottom surface 162 . The conductive element 18 includes a front end 180 positioned outside the upper surface 160 and a rear end 182 ( figure 2 shown). The positive pole and the negative pole of the power supply 11 are respectively connected to the workpiece 12 and the front end 180 of the conductive element 18 . In addition, in some embodiments, the positive pole and the negative pole of the power source 11 may also be connected to the front end 180 of the conductive element 18 and the workpiece 12 respectively. In this embod...

Abstract

The invention relates to an electrode device and a method for electromachining a workpiece. The electrode device comprises an electrode, a power supply and a machining liquid source, wherein the electrode comprises a tubular element and a conducting element; the tubular element is internally provided with a pipeline; the conducting element is movably accommodated in the pipeline and extends to form the tubular element so as to machine the workpiece; the power supply can ensure that the conducting element and the workpiece have opposite polarities; and the machining liquid source can provide machining liquid passing through the conducting element and the workpiece.

Description

technical field [0001] The invention relates to an electrode device and an electric processing method, in particular to an electrode and an electric processing method for processing desired structural features on a workpiece. Background technique [0002] Electromachining technology has been widely used to process workpieces, such as gas turbines. Taking a gas turbine as an example, the higher the temperature of the gas entering it, the higher the efficiency of the gas turbine. However, high temperature gas results in a high temperature operating environment. In this way, in order to withstand the high temperature during operation, the turbine blades in the gas turbine are often made of advanced materials, especially the advanced cooling technology is used to cool the blades. [0003] Typically, a coolant, such as compressed gas, is used to cool the blades. One or more cooling holes are processed in the blade to facilitate the passage of gas. In particular, a cooling str...
