|Preparation method and application of self-sharpening sintered abrasive|
|Release time: 2017-1-11|
A method and application for preparing self-sharpening sintered abrasives, which are characterized in that high-quality sintered abrasives are obtained by measuring the required raw materials in terms of percentages, mixing, cementing, crushing, classification, sintering, and post-processing. The sintered abrasive has a proper self-sharpening property. During the grinding process, the sintered large particles do not fall off entirely, but the binder between the small particles of the raw materials inside the sintered abrasive is fatigued and destroyed, and then broken. The abrasive particles fall off one by one. The sintered abrasive provided by the invention has good self-sharpening properties, which is beneficial to stabilize the processing efficiency and improve the utilization rate of the abrasive. It can be used in processing processes such as grinding, polishing, honing, sawing, etc. Finished tools such as honing heads and saw blades. The method provided by the invention has the advantages of simple process, high yield and low cost.
