中文摘要：

激光光斑直径小,能量密度高,与智能化数控系统技术结合,可以实现金刚石磨粒的有效排布。文章利用Nd：YAG脉冲型固体激光器,通过控制合理钎焊工艺,实现对两种Ni-Cr合金粉末钎料与金刚石、基体的牢固焊接。

英文摘要：

Effective configuration of diamond abrasive grains can be achieved through combination of laser and intelligent numerical control system technique as laser has small spot diameter and high energy density.Two types of Ni-Cr alloy powder brazing filler metals have been securely welded with diamond and matrix by Nd：YAG pulse type solid-state laser through controlling the proper brazing technique.
