电镀金刚石砂轮的接触修整是精密成形磨削中一项具有挑战性的技术。本文提出了一项研究，旨在探索现代激光技术用于接触式修整的能力。使用脉冲皮秒激光（ps 激光）束 (Yb:YAG) 在明确的晶粒突出范围内切割金刚石晶粒，而不会对镍结合剂材料和金刚石本身造成明显的热损伤。对激光照射参数对切割质量的影响进行了系统研究。进行了使用超短脉冲激光源修整 SiC 砂轮和传统接触修整金刚石砂轮的一系列实验，并对两种方法进行了比较。介绍了新型激光方法的显着优点。
Touch dressing of electroplated diamond wheels is a challenging technique used for precision form grinding. This paper presents an investigation to explore the capabilities of modern laser technology for touch dressing. A pulsed picosecond laser (ps-laser) beam (Yb:YAG) is used to cut diamond grains within a definite grain protrusion without noticeable thermal damage neither on the nickel bond material nor the diamond itself. A systematic study on laser irradiation parameters on cutting quality is presented. Series of experiments by dressing of SiC wheels using an ultrashort pulsed laser source as well as conventional touch dressed diamond wheel are carried out and both methods are compared. Significant advantages of the novel laser method are presented.
