Diamond (PCD) tools are divided into: PCD reamers, PCD milling cutters, PCD turning tools, PCD drill bits, CVD diamond coating tools and other non-standard forming tools according to their structure.
As a kind of diamond (PCD) tool, CVD diamond coated tool is widely used in graphite electrode milling, MMC metal matrix composite drilling and milling, CFRP composite drilling and milling, zirconia ceramic drilling and milling and other fields. With its advantages of high hardness, strong wear resistance and low affinity with non-ferrous metals, CVD diamond-coated tools have become the ideal tool for machining a series of difficult-to-machine materials such as graphite electrodes, zirconia ceramics, MMC metal matrix composites, and CFRP composites. The only choice.
Diamond-coated tools have a series of graphite properties such as high abrasiveness, high temperature resistance, and good electrical conductivity. They are widely used in molds, crucibles, electrodes, batteries, brushes, etc., especially graphite electrodes, and new energy vehicle batteries. The graphite plate in the middle is very common, but because the graphite is hard and brittle, it is easy to collapse in the traditional processing process, causing the workpiece to be scrapped, while the high hardness, high wear resistance, sufficient strength and impact toughness Diamond tools have gradually become the mainstream tools for graphite processing. In the field of graphite processing, in addition to the PCD turning tools made of CDW302 and CDW010, the commonly used CVD diamond-coated tools are mainly graphite-specific milling cutters.
As a special tool for graphite machining, the cutting edge of the graphite milling cutter has been specially optimized, which can effectively reduce the cutting resistance and have higher efficiency. High-efficiency machining meets the processing requirements of large-scale, high-efficiency, and high-precision machining centers. In addition, the sharp and wear-resistant characteristics of graphite milling cutters can also reduce the number of tool changes and increase tool life by nearly 10-20 times. This series of reasons makes CVD diamond-coated tools become the darling of graphite processing.
