The invention relates to the technical field of ultra-hard honing, in particular to a preparation method of a mixed ultra-hard honing oil stone. The preparation method of the mixed ultra-hard honing oil stone is characterized in that diamond with the surface being subjected to tungsten-plating metallization and cubic boron nitride (CBN) with the surface being subjected to tungsten-plating metallization are used for preparing the honing oil stone as abrasive materials. The preparation method comprises the steps that firstly, the molten salt process and magnetron sputtering tungsten-plating pretreatment are conducted on diamond abrasive particles and CBN abrasive particles; secondly, the pretreated abrasive particles and metal bonding agent powder are subjected to ball milling after being mixed according to a certain proportion; and thirdly, mixed powder subjected to ball milling is placed in a graphite mold to be hot-pressed and sintered or is placed in a steel mold to be pressed into a blank, and non-pressure
