金刚石砂轮是磨削硬质合金、玻璃、陶瓷、宝石等高硬脆材料的特效工具。近几年来,随着高速磨削和超精密磨削技术的迅速发展,对砂轮提出了更高的要求,陶瓷和树脂结合剂的砂轮已不能满足生产的需要,金属结合剂砂轮因其结合强度高、成型性好、使用寿命长等显著特性而在生产中得到金属结合剂金刚石砂轮按制造方式不同主要有有烧结和电镀两种类型。关于金刚石砂轮,电镀金刚石砂轮,钎焊金刚石砂轮的信息

金刚石砂轮是磨削硬质合金、玻璃、陶瓷、宝石等高硬脆材料的特效工具。近几年来,随着高速磨削和超精密磨削技术的迅速发展,对砂轮提出了更高的要求,陶瓷和树脂结合剂的砂轮已不能满足生产的需要,金属结合剂砂轮因其结合强度高、成型性好、使用寿命长等显著特性而在生产中得到金属结合剂金刚石砂轮按制造方式不同主要有有烧结和电镀两种类型。为了充分发挥超硬磨料的作用,国外从20世纪90年代初开始用高温钎焊工艺开发一种新型砂轮,即单层高温钎焊超硬磨料砂轮,目前国内这种砂轮还处于研制开发阶段。

近年来各国学者相继开展了应用特种加工方法修整金属结合剂金刚石砂轮的研究工作,主要有电解修整法、电火花修整法和复合修整法等。电解修整法速度快,但整形精度不高;电火花修整法整形精度高,既可整形又可修锐,但整形速度较慢;复合修整法有电解电火花复合修整法、机械化学复合修整法等,修整效果较好,但系统较复杂,因此烧结型金刚石砂轮的修整问题仍然没有得到很好的解决。
