摘　　要：特定的生产或试验条件下不同的磨料制作的砂轮具有不同的性能表现,为了考察市售微晶陶瓷磨料(CA)的适用性,选取四种不同品牌相近规格的CA磨料制作新型CA磨料砂轮进行磨削试验,以等效组分等量替代法采用相同的砂结比、成型、干燥等工艺技术条件,制成砂轮样品并分别编号为1^(#)~4^(#),对轴承钢工件进行磨削试验,比对磨削比、磨削功率的变化以及磨削后工件表面质量、砂轮表面形貌特征,了解该工艺技术条件下不同CA磨料制得的低温陶瓷结合剂砂轮的性能.结果表明,1^(#)和2^(#)磨料制作的砂轮综合磨削性能较好,4^(#)无明显优势,但磨削后工件表面光洁度较好,3^(#)砂轮表现不佳.The performance of grinding wheels varies based on the abrasive materials used and the specific production or testing conditions.The study aimed to assess the suitability of commercially available microcrystalline ceramic alumina(CA)abrasive by creating new grinding wheels using four similar abrasive materials for testing.The grinding wheel samples were labeled 1^(#) to 4^(#) using the equivalent component substitution method and subjected to consistent process conditions.Grinding tests on bearing steel workpieces were conducted to compare grinding ratio,power,workpiece surface quality,and grinding wheel topography for different CA abrasive-made grinding wheels under specific process conditions.Findings indicate better comprehensive grinding performance with 1^(#) and 2^(#) abrasives,no significant advantage for 4^(#),improved workpiece finish post-grinding,and poor performance for the 3^(#)grinding wheel.
