1. Introduction. Graphite ore is a mineral exclusively composed of sp 2 hybridized carbon atoms with p-electrons, found in metamorphic and igneous rocks [1], a good conductor of heat and electricity [2], [3] with high regular stiffness and strength. Note that graphite (plumbago) can maintain its hardness and strength at a temperature of up …

These coatings are grown directly into the carbide end mill, improving the hardness and leaving the tool with a coating layer that is 5 times thicker than a PVD Diamond Coating. While not the sharpest edge, the CVD diamond coating provides much longer tool life than other diamond coatings due to the thicker diamond layer.
(1) First find out the type of graphite ore. Graphite ore is divided into flake graphite ore and earthy graphite ore. The scaly graphite ore is characterized in that the graphite is scaly or leaf-shaped, and the raw ore grade is not high, generally 3% to 5%, and the highest does not exceed 20% to 25%.
