播 要：研究了復(fù)合片外圖房刑用陶近結(jié)合刑金明石砂輪的制備工藝只其應(yīng)用■確定了合適的工藝歩數(shù). 結(jié)果表明*自制Li-Al-B-Si-0系低溫陶近結(jié)合劑含童在22%?26%時，矽輪的綜合，14能達(dá)到最伐： 砂輪中舟料濃度越高，使用效果越好，隨矽輪中房軒濃度的增加?砂輪的性價
2、比遂漸提離，當(dāng)濃度達(dá)列 210%時?矽輪的壽令達(dá)到瓷砂輪比樹脂砂輪的壽令提高2?3倍，且單件復(fù)合片的庭利效率提高 約30%$所研甸的低溫陶先金剛石砂輪妹合柱能達(dá)到國內(nèi)領(lǐng)先水平具有較高的性價比.

Abstract：The preparation and application of vitrified bond diamond grinding wheel for PCD cylindrical grinding use hav
4、e 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-0 series vitrified bond content is about 22% ? 26%; diamond concentration brings good effect on its application until
5、 the concentration up to 210%f the wheel reaches the longest life; working life of vitrified bond grinding wheel are much longerf 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 develope
6、d low temperature vitrified bond grinding wheels reaches the leading level and is much competitive.
