Graphite is a non-metallic material and is widely used in graphite molds, graphite crucibles, graphite battery plates, etc., especially in today's increasingly serious energy and environmental pollution problems, the development of new energy vehicles has been the implementation of national energy conservation and emission reduction, and the development of the low-carbon economy. As one of the key parts of the fuel cell that drive the new energy vehicle, the performance of the graphite plate directly affects the output power and service life of the entire battery stack, so its quality is required to be high.
Although graphite is a free-cutting material, it is easy to break due to brittleness, edge chipping, and tool wear during processing, which affects the surface quality of the product. It is recommended to use Halnn superhard PCD tools for turning, such as CDW010 and CDW025 grade.
Some enterprises in graphite turning use cemented carbide tools to process, and it is often said that they are not wear-resistant and have a too short lifespan, but this problem does not occur when using PCD tools. PCD tools are synthetic polycrystalline diamond tools with extremely high hardness and can be made of PCD inserts, PCD milling cutters, PCD drills, PCD non-standard forming knives, and other structural forms.
The PCD tools for turning graphite were mainly welding tools in the early days. At present, CNC blades have been used instead of welding tools to process graphite. The PCD CNC blades of CDW010 and CDW025 grade belong to the national standard model, which is convenient to match with the turning tool holder and is easy to disassemble and replace. Both CNC lathes and machining centers can be used. Compared with traditional carbide inserts, higher linear speeds can be used for machining, and the tool life is also greatly improved.
In addition to PCD inserts, for graphite parts, Halnn Superhard can also provide PCD rod-shaped milling cutters and milling inserts, PCD drill bits, diamond-coated tools, and other products, providing a complete cutting solution for graphite processing.
The tool structure of graphite milling tools includes rod-shaped milling cutters and milling inserts. The types are PCD end mills, PCD ball end mills, PCD single-edged milling cutters, PCD double-edged milling cutters, PCD slot milling cutters, PCD Chamfering cutters, diamond PCD face milling cutters, PCD milling inserts PCD CVD diamond coating milling cutters, etc.
The forms of graphite hole processing tools are PCD drill bit, PCD inner hole turning tool, PCD boring tool, PCD milling cutter, CVD diamond coated drill bit, etc.
