激光处理是一种新的、有前途的非常规方法，可以降低超硬材料刀具的修整成本和时间。本文从理论和实验两方面研究了皮秒激光对金属结合剂立方氮化硼(CBN)和金刚石超硬材料刀具表面的热效应。该分析方法旨在为超磨料颗粒和粘结材料的选择性烧蚀寻找阈值工艺参数。利用微微秒Yb：YAG激光器对金属结合剂CBN和金刚石珩磨刀具进行了激光辐射实验。分析和实验证明，采用合适的工艺参数，对超硬磨料刀具零件进行选择性和可控处理是可能的。
Laser treatment is a novel and promising non-conventional method to reduce the conditioning costs and time of superabrasive tools. In this study, the thermal effects of picosecond laser radiation on metal-bonded cubic boron nitride (CBN) and diamond superabrasive tool surfaces have been analytically and experimentally investigated. The analytical approach is intended to find threshold process parameters for the selective ablation of the superabrasive grains and the bond material. The laser radiation experiments have been conducted with a picosecond Yb:YAG laser on metal-bonded CBN and diamond honing tools. It has been analytically and experimentally demonstrated that, using suitable parameters, the selective and controlled treatment of superabrasive tool components is possible.
