graphite electrode joint
Machining requirements and characteristics of graphite electrode joint
1. The production of graphite electrode joint. The production of professional graphite electrode joint 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. The ordinary machine tool can also complete the electrode processing, but the process of programming the tool is different from the related process of the copper electrode.
2. EDM electrical discharge machining. The graphite electrode joint 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 joint. Industrial graphite is hard and brittle, and the tool wear is more serious during CNC machining. Generally, it is recommended to use cemented carbide or diamond-coated tools. When roughing graphite, the tool can be directly up and down on the workpiece. In order to avoid chipping and chipping during finishing, a light tool is often used for processing. Generally speaking, graphite seldom collapses when the cutting depth is less than 0.2mm, and good sidewall surface quality can be obtained. The graphite electrode joint generates a lot of dust during CNC machining. These dusts may enter 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 sealing of the machine tool should also be good, because of natural graphite Contains impurities and is toxic. CGM New Material Co., Ltd. is a manufacturer of graphite electrode joint. Its main products include graphite electrode joint, graphite products, graphite recarburizers, etc.!
