Abstract
The utility model relates to the technical field of diamonds and provides a high-end diamond compact. The high-end diamond compact is characterized by comprising a hard alloy layer, a diamond compact layer and a diamond layer, wherein one surface of the hard alloy layer is of a city wall shape, the diamond particle size of the diamond compact layer ranges from 5 micrometers to 10 micrometers, the diamond compact layer is sintered onto the hard alloy layer, the diamond particles of the diamond layer is nearly spherical and 1-1.1 in terms of ratio of long axis to short axis, and the diamond layer is sintered onto the surface of the diamond compact layer. The high-end diamond compact has the advantages that diamond power on the high-end diamond compact is low in impurity, high in relative intensity, even in particle size, neat in crystal form and high in smoothness of machined workpieces, and the service life of the diamond compact is prolonged greatly. Due to the fact that the shape the diamond power on the diamond compact is nearly spherical, compared with common irregular diamond powder, the spherical diamond power can increase wear resistance of the diamond compact greatly.
