Diamond tools are not suitable for chipping metal

Today Xiaobian to introduce to you why diamond tool is not suitable for chipping metal, hurry to learn!
Metal-matrix composites can be machined with diamond in either dry cutting or wet cutting. However, because of the low thermal stability of diamond, it will be carbonized (i.e., graphitized) at 700-800℃, which dramatically reduces the life of diamond tool. If the cutting fluid wet cutting, the cutting temperature can be reduced, so that the tool life is increased. But before the cutting tool into the workpiece should be pouring cutting liquid until the cutting is finished, the cutting fluid needs to be supplied continuously, not intermittently, otherwise easy to cause tool damage or collapse. In the same way, in the cutting process should also try to avoid stopping or changing the cutting parameters.
Diamond is natural stone or man-made building material, in the final analysis is stone, but it is higher than other stone Mohs hardness, 10, compared with metal hardness is not entirely. In addition, metals have a high melting point. Likewise, diamond hardness decreases when heat is generated during friction.
The above is about the diamond tool is not suitable for chipping metal content introduction, do you understand?
