Graphite electrode nipple electromechanical processing requirements and characteristics
1. Electrode production
The production of professional graphite electrode nipple is mainly processed by high-speed machine tools. The stability of the machine tool should be good, the three-axis movement should be uniform and stable without vibration, and the rotation accuracy of the spindle should be as good as possible. Electrodes can also be processed on general machine tools, but the process of programming toolpaths is different from that of copper electrodes.
2. EDM electrical discharge machining
The graphite electrode nipple is a carbon electrode. Because graphite has good electrical conductivity, it can save a lot of time in electrical discharge machining, which is one of the reasons why graphite is used as an electrode.
3. Processing characteristics of graphite electrode nipple
Industrial graphite is hard and brittle, and it wears more severely to the tools during CNC processing. Generally, it is recommended to use carbide or diamond-coated tools. During rough machining of graphite, the tool can be directly up and down on the workpiece. In order to avoid chipping and chipping during finishing, the method of light knife and fast walking is often used. Generally speaking, graphite seldom collapses when the cutting depth is less than 0.2mm, and good sidewall surface quality can be obtained.
The dust generated during graphite electrode nipple CNC machining is relatively large, which may invade the guide screw and spindle of the machine tool. This requires the graphite processing machine tool to have a corresponding device for processing graphite dust, and the machine tool must have good airtightness, because graphite is poisonous.
