Abstract

The invention discloses a self-sharpening diamond grinding wheel and a preparation technology of the self-sharpening diamond grinding wheel. The self-sharpening diamond grinding wheel is prepared from, by mass, 50-60 parts of diamond powder, 4-11 parts of Sn powder, 12-18 parts of Cu powder, 15-25 parts of Al powder, 0.5-1.1 parts of La powder, 3-7 parts of Ni powder, 10-20 parts of Co powder, 7.9-17.6 parts of ceramic powder, 1-5 parts of Fe powder, 1-3 parts of Cr powder, 1-3 parts of Ti powder, 1-3 parts of MoS2 powder, 5.6-12.1 parts of SG grinding materials, 0.9-1.8 parts of additive and1-3 parts of acrylic emulsion. The self-sharpening diamond grinding wheel has the beneficial effects that the bonding strength of tire body materials for diamond is improved and reinforced, the grinding wheel has the good mechanical property and self-sharpening performance through formula synergy, therefore, the diamond grinding wheel with the high strength and self-sharpening performance is obtained, and the grinding wheel is evenly consumed in the grinding process.

Description

technical field [0001] The invention relates to the technical field of grinding wheel preparation, in particular to a self-sharpening diamond grinding wheel and a preparation process thereof. Background technique [0002] Modern machining is developing in the direction of high precision, high speed, hard machining, dry machining (no coolant) and cost reduction, which puts forward quite high requirements for the performance of superhard abrasive tools. Currently commonly used superhard grinding materials include cubic boron nitride (CBN) and diamond abrasives. Although the hardness of CBN abrasive is inferior to that of diamond, its thermal stability and chemical stability are strong, especially it will not react with iron and iron alloys, so it can be used in iron-based alloy materials such as hardened steel, high-speed tool steel, bearing steel, stainless steel, It has been widely used in the grinding of many high-strength toughness difficult-to-machine materials such as d...
