一、滚抛磨具很早以前人们就用无介质或介质(如木屑、铁屑、鹅卵石、燧石、石灰石、石榴石、天然刚玉以及石英砂等)滚抛加工工件。至今在我国还有相当数量的工厂仍在使用这些介质材料,但在一些先进工业国家里(如美国、西德、日本等)已用人造滚抛磨具加工工件了。滚抛磨具是以磨料为主体,用陶瓷或有机结合剂粘结成所需要的形状并经过一定的温度烧制或硬化而成。这种产品的特点是硬度适宜、组织结构致密,耐用度高又具有一定的自锐性。
First, throwing abrasive A long time ago, people use no medium or medium (such as sawdust, iron filings, pebbles, flint, limestone, garnet, natural corundum and quartz sand, etc.) roll processing workpiece. So far there are still a large number of factories in our country still using these media materials, but in some advanced industrial countries (such as the United States, West Germany, Japan, etc.) have been using a man-made roller polishing the workpiece processing. Abrasive is abrasive abrasive as the main body, with ceramic or organic bonding agent bonded into the desired shape and after a certain temperature firing or hardened. This product is characterized by appropriate hardness, compact structure, high durability and has a certain degree of self-sharpening.
