EDM Parameters of Silver Tungsten Alloy

EDM process parameters can be divided into electrical and non-electrical parameters parameters. The main parameters of the electrical parameters of pulse power is there between processing polarity, pulse width, pulse peak voltage, peak current, and so on. Non-electric parameters are mainly flushing or pumping the way, pressure, flow, carrying knives height, frequency, translational mode, the size of the flat momentum, they influence each other, allelopathy, to select the parameters more difficult.

In order to correctly select the gage EDM parameters to follow, people under the tool electrode material of the workpiece, if the tool polarity, pulse width, peak current, etc. The main parameters of the surface roughness, the discharge gap, ablation rate The four main process indicators affect electrode wear rate and, prior to make technology curve chart, click here to select EDM gage.

EDM machining mold or some parts, usually workpiece material has been previously set, carbon steel, tool steel, stainless steel, nickel-chromium alloy steel of various types of steel material and so can be counted on the EDM, they are is processing performance, process indicators are similar. Including melting point, high vaporization point of tungsten, molybdenum alloys and carbide materials and graphite, copper, tungsten, silver, tungsten sintered materials, conductive polycrystalline diamond, etc. can be counted as another kind of processing power are difficult for them processing materials. Aluminum, zinc, brass and other low melting point of the material, EDM easier. In short, the first step is we analyze the characteristics and technical requirements of the workpiece (eg rough surface, size, tolerance precision) and other technology indicators on the basis of the workpiece material and technical requirements to select the tool electrode materials such as brass, copper, stone or copper tungsten, silver tungsten alloys, of course, to consider whether they are easy to manufacture a tool electrode and the costs and other factors.
