Do you know the Application of Ultra-Fine Graphite Rods As Graphite Electrodes?
As a Graphite Electrodes Manufacturer , share it with you. Ultrafine graphite is a new type of graphite material developed in the 1970s, mainly used for precision machining electrodes of EDM machine tools. As an electrode material, it first needs to conduct electricity and heat. In EDM, due to partial discharge, the temperature of the gap between the electrode and the workpiece is 2000-3000°C, so the electrode material needs to withstand high temperatures. If the melting point of the electrode material is low, it cannot be processed quickly with a high current, the processing speed is low, and the processing cost increases. In theory, tungsten or tungsten alloy is the best electrode material. The tungsten electrode has the characteristics of high strength, high density, and melting point close to 3400℃. The actual loss of tungsten electrode in EDM is very small. Graphite Electrodes However, tungsten electrodes have two problems: 1. Tungsten is difficult to process. 2. The ...
