Abstract

The invention relates to a manufacturing method of grinding materials and grinding tools, in particular to a preparation method for wear-resisting man-made oilstone. According to the preparation method, silicon dioxide, aluminum oxide, zirconium oxide and boric acid serve as main raw materials, ball milling powder is processed to obtain ceramic binder fragments, the ceramic binder fragments are subject to ball milling, drying and screening to obtain ceramic binder powder, rice hull ash is used as a raw material, palm wax and pericarp are added, fermentation is carried out under the ammonia atmosphere to obtain fermentation filter residues, the fermentation filter residues and diamond particles are mixed to obtain rigid powder, diamond-silicon carbide composite powder is obtained through roasting, and then the diamond-silicon carbide composite powder and additives such as magnesia powder and white corundum are mixed to obtain a to-be-sintered material; and finally, the to-be-sintered material is placed into a graphite jig, the wear-resisting man-made oilstone is obtained through processing, in the rice hull ash fermentation process, the micro rotting effect of microorganisms in thepericarp is used for fixing nitrogen in ammonia gas into the fermentation filter residues, the wear-resisting property of the man-made oilstone and the grinding effect on the high-hardness materials are improved, and the application prospect is wide.

Description

technical field [0001] The invention relates to a method for manufacturing abrasive abrasives, in particular to a method for preparing wear-resistant artificial whetstone. Background technique [0002] Whetstone is a strip-shaped consolidated abrasive tool made of abrasives and binders. It is usually lubricated when used, so it is called Whetstone. Whetstones are generally used for manual grinding of tools and parts, and can also be clamped on machine tools for honing (also known as boring and grinding, which refers to the use of honing whetstones embedded in the honing head to smooth the surface of the workpiece at a low cutting speed. The method is a special form of grinding, which mainly processes various cylindrical holes with a diameter of 5 to 500 mm or even larger, and the ratio of the hole depth to the hole diameter can reach 10 or more) and superfinishing. [0003] There are two types of whetstones: man-made and natural. Natural whetstones are processed from natura...
