挤压珩磨也称磨料流动加工,是表面抛光和去毛刺的一项新技术。它是七十年代初由美国发明的,最初主要用于去除零件内部隐蔽部分或交叉孔中的毛刺,随后扩大应用到抛光多种类型模具和零件的表面,光洁度一般可提高3级左右,最高光洁度可达镜面。可用于去除电火花加工或激光加工所产生的表面硬化层,或抛光电火花加工后的模具表面;同时可用于棱边倒圆、消除表面应力或微观缺陷;也可作为一般机械加工,如拉削、镗削和铣 Extruded honing, also known as abrasive flow machining, is a new technique for surface finish and deburring. Originally invented in the United States in the early 1970s, it was primarily used to remove burrs from hidden parts or cross-holes in parts and was subsequently expanded to polish the surface of many types of molds and parts. The finish is generally about 3 steps higher, Finish up to the mirror. Can be used to remove the EDM or laser processing of the surface hardened layer, or polishing EDM mold surface; the same time can be used for edge rounding, to eliminate surface stress or micro-defects; also be used as a general machining, such as pull Shaving, boring and milling
