鉴於现代化机构零件工作表面质量要求的提高,镗磨被广泛用作精加工,以保证加工表面高的光洁度及机器质量的改善。 镗磨通常使用粘土结合剂的砂条,但粘土结合剂有以下重大缺陷: 1.由於粘土结合剂的易脆性,砂条易於崩落。磨料崩落的微粒落於砂条工作面及待加工表面间,使工件形成 In view of the improvement of the working surface quality of the parts of modern institutions, the boring mill is widely used as finishing to ensure the high surface finish and the improvement of the machine quality. Boring often involves the use of clay-bonded sand bars, but clay binders have the following major drawbacks: 1. Sand bars tend to slump due to the brittleness of the clay binders. The abrasive particles fall on the sand surface and the surface to be processed, so that the workpiece is formed
