Application of diamond tools in the electrical and electronic industry

The diamond wire drawing die can control various wire wires of the electronic and electrical industry from millimeters to micrometers in diameter. Accuracy can reach 1~2 microns. For example, micron-sized platinum wire, tungsten wire, and ultra-fine copper wire are drawn. Can withstand high pressure, friction, and hundreds of degrees of high temperature, not easy to wear and deformation. Durability is tens to hundreds of times the drawing die of cemented carbide.
The polycrystalline diamond wire drawing die is more unique than the natural diamond wire drawing die. There is no anisotropy of natural diamond and it is not easy to split. The wire drawing holes can always maintain a perfect circle. It is worth noting that although the hardness of polycrystalline diamond is lower than that of natural diamond, the life is longer than the latter, and the life of a good polycrystalline diamond drawing die is several times that of natural diamond. The price is only 1/3~1 /5 of the natural diamond drawing die. The use of some transition metals is poor, and the polishing of the drawing holes is also difficult.
Ferrite magnetic materials used in the electrical industry and some insulating materials, such as cloth bakelite, epoxy fiberboard and other insulating materials, processed with diamond sheet grinding wheels, with less waste and high efficiency, solving the burns when cutting with other tools. Problems such as poor roughness, inaccurate size, and waste. The processing of high-aluminum ceramic insulators is also unique. For example, it can process high-voltage electric porcelain containing 35% of corundum, which is difficult to process with silicon carbide.
