Abstract
The present invention relates to a diamond surface coating glass, coating cubic boron nitride and plating titanium composite structure and the manufacturing method thereof. The surface of a diamond is provided with a glass layer. A cubic boron nitride layer is arranged on the glass layer. The surface layer of the cubic boron nitride layer is provided with a titanium layer. The present invention has the main advantage that cubic boron nitrides in the inner surface layer of the diamond are inert to iron element materials and the surface of the cubic boron nitrides is rough. The outer layer of the diamond is coated by a metallic titanium layer. The present invention is a special abrasive grain having the performance of the two abrasive materials of the diamond and the cubic boron nitrides and having the structural performance of rough and fine abrasive grains. When the special abrasive grain is used to manufacture grinding tools of resin bonding agent to process cutters, tools and workpieces made of hard alloy and iron element materials, workpiece quality with special requirements can be obtained. The diamond which experiences composite coating and plating treatment has an increased volume and the shape of the diamond is similar to a ball. Grinding tools made of the diamond are uniformly provided with the diamond abrasive grains. Simultaneously, the bonding strength and the holding force of the diamond and a basal body are big, which prevents the abrasive grain from dropping off soon. The diamond having the compound coating and plating layer of the coating glass, the cubic boron nitrides and the plating titanium is mainly used for the grinding tools of resin bonding agent. When the diamond is used, compound grinding effect of the diamond, the cubic boron nitrides and the rough and fine abrasive grains can be achieved.
