磨料(abrasive)在磨削、研磨和抛光中起切削作用的颗粒状材料。磨料主要用于制造磨具,也可以直接用于某些研磨和抛光工作。磨料应具有以下基本性质:①较高的硬度,一般应高于被加工材料;②适当的强度,在磨粒切刃还锋利时能承受切削力而不碎裂,当切刃磨钝到一定程度时能局部碎裂而露出新的 Abrasive A granular material that acts as a cutting tool in grinding, grinding, and polishing. Abrasive is mainly used to make abrasive tools, can also be used directly for some grinding and polishing work. Abrasive should have the following basic properties: ① higher hardness, the general should be higher than the material being processed; ② the appropriate strength, the abrasive cutting edge is sharp and can withstand the cutting force without fragmentation, when the cutting edge blunt to a certain Degree of fragmentation can be partially exposed to new
