| 摘 要： | 陶瓷结合立方氮化硼(CBN)磨削工具是一类用于磨削加工的新型陶瓷/玻璃复合材料。本文作者从复合材料制备理论角度探讨了这类材料的制备原则,并进行了试验研究。研究结果表明:CBN磨具的烧成温度以低于800℃为宜;陶瓷结合剂与CBN磨料的热膨胀系数匹配性对磨具强度有较大影响,具有较小热膨胀系数和较高强度的C1结合剂较适合CBN磨具制备。在一定温度范围内,适当提高烧结温度,有利于提高陶瓷结合剂桥相本身强度及结合剂与CBN磨料颗粒的结合强度。

| Abstract: | Vitrified bond cubic boron nitride (CBN) grinding tools are new ceramic/glass composites for grinding. This paper discussed the manufacturing principles of these materials in terms of composites theory and prepared such materials experimentally with success. The results showed that the suitable sintering temperature of vitrified bond CBN grinding tools should be lower than 800 ℃. The strength of vitrified bond CBN grinding tools was obviously affected by the difference of thermal expansion coefficient between vitrified bond and CBN abrasives. C1 bond was more suitable for the manufacturing of vitrified bond CBN grinding tools. Within the sintering temperature range, relatively higher sintering temperature was beneficial to the strength of the bond bridge and the holding strength between bond and CBN abrasive particles. |
