三、研磨剂材料(1)研磨粉:最常用的研磨粉有刚玉、白色刚玉、黑色碳化硅、绿色碳化硅、碳化硼、氧化铬、氧化铁(即铁丹粉)等。白色刚玉和绿色碳化硅用于粗、精研磨,氧化铬和氧化铁用于抛光。各种研磨粉的性能及其应用见表6。研磨粉颗粒结晶经过粉碎后,尺寸大于0.028毫米的用稀分法(每时长度内的稀孔数)来表示其粒度;
Third, the abrasive material (1) grinding powder: The most commonly used grinding powder corundum, white corundum, black silicon carbide, green silicon carbide, boron carbide, chromium oxide, iron oxide (ie, iron oxide powder) and so on. White corundum and green silicon carbide for coarse, fine grinding, chromium oxide and iron oxide for polishing. The performance of various grinding powders and their applications are shown in Table 6. Grinding powder particles after crushing, the size is greater than 0.028 mm with the dilution method (the number of pores per time length) to represent the size;
