摘    要:研究了复合片外圆磨削用陶瓷结合剂金刚石砂轮的制备工艺及其应用,确定了合适的工艺参数。结果表明:自制Li-Al-B-Si-O系低温陶瓷结合剂含量在22%~26%时,砂轮的综合性能达到最佳;砂轮中磨料浓度越高,使用效果越好,随砂轮中磨料浓度的增加,砂轮的性价比逐渐提高,当浓度达到210%时,砂轮的寿命达到最高;陶瓷砂轮比树脂砂轮的寿命提高2~3倍,且单件复合片的磨削效率提高约30%;所研制的低温陶瓷金刚石砂轮综合性能达到国内领先水平,并具有较高的性价比。

关 键 词:复合片  外圆磨削  陶瓷结合剂  金刚石砂轮

Abstract:The preparation and application of vitrified bond diamond grinding wheel for PCD cylindrical grinding use have been investigated and proper technique parameters have been developed.The results show that: grinding wheels give the best comprehensive performances when the self-made Li-Al-B-Si-O series vitrified bond content is about 22% ~26%;diamond concentration brings good effect on its application until the concentration up to 210%,the wheel reaches the longest life;working life of vitrified bond grinding wheel are much longer,about 2~3 times more than resin wheel and efficiency of grinding a single PDC can be improved about 30% compared to resin wheel;comprehensive performance of the developed low temperature vitrified bond grinding wheels reaches the leading level and is much competitive.
Keywords:PDC  cylindrical grinding  vitrified bond  diamond grinding wheel
