【摘要】：砂轮是磨削加工技术中使用最为广泛的加工工具,但传统磨粒砂轮其磨粒与结合剂之间结合面积小,砂轮表面磨粒无规则随机排布,存在磨削时法向力与切向力之比高、磨削比能高和磨削温度高等问题,影响了零件加工质量及效率,降低了砂轮使用寿命。有序化砂轮是利用现代加工制造方法使得磨粒在其表面形成规则化、序列化排布模式的一种新型砂轮,其优点是可以提高动态有效磨粒的比例,增加砂轮容屑空间,有效降低磨削温度,延长砂轮的使用寿命以及提高加工表面质量。综述了近年来有序化成型方法、有序化砂轮排布方式和加工性能,以及有序化纤维砂轮的研究现状及进展,以期为有序化砂轮的应用提供更为广阔的市场空间。
[Abstract]:Grinding wheel is the most widely used machining tool in grinding technology, but the traditional abrasive wheel has a small binding area between abrasive particles and binder, and the abrasive particles on the surface of grinding wheel are arranged randomly and irregularly. The problems of high ratio of normal force to tangential force, high specific energy of grinding and high grinding temperature have affected the machining quality and efficiency of parts. The ordered grinding wheel is a new type of grinding wheel which can make the abrasive particles form regular and serialized arrangement mode on its surface by using modern machining and manufacturing methods. It has the advantages of increasing the proportion of dynamic effective abrasive particles, increasing the space of grinding wheel, reducing grinding temperature, prolonging the service life of grinding wheel and improving the quality of machined surface. The ordering molding methods in recent years are reviewed. In order to provide a wider market space for the application of ordered grinding wheel, the arrangement mode and processing performance of ordered grinding wheel and the research status and progress of ordered fiber grinding wheel are also discussed in this paper.
