The processing methods of graphite molds, graphite electrodes and other products are mainly turning, milling, and drilling. Because graphite products are hard and brittle, if the tool is not selected correctly during processing, it is easy to cause collapse. Then, processing graphite What kind of tool should be selected for the finished product?
The material of the tool is the fundamental factor determining the cutting performance of the tool, and has a great influence on the processing efficiency, processing quality, processing cost and tool durability. However, due to the hardness and brittleness of graphite products, cutting tools must have high hardness and high wear resistance, sufficient strength and impact toughness, and good machinability. Currently, the commonly used tool material is mainly diamond (PCD). .
Diamond (PCD) tools have many structures, such as PCD milling cutters, PCD reamers, PCD drills, PCD turning tools, CVD diamond-coated tools, etc., but in the field of graphite products, PCD turning tools and diamond-coated milling cutters are mainly used Mainly, the commonly used PCD turning tools are CDW302 material and CDW010 material, which have high processing efficiency. The CVD diamond-coated milling cutter is mainly HPD graphite special milling cutter.
