一、综述 1989年印度学者首先发明了用激光修整普通SiC和Al_2O_3砂轮,在他们的试验中,先用金刚石修整砂轮,再用普通脉冲YAC激光垂直辐照砂轮表面,每个脉冲在砂轮表面打出一个小坑,通过相对运动,将这些小坑部分重叠起来,得到经过激光修整的砂轮表面,磨削试验表明,经过激光修整和经过金刚石修整的砂轮的磨削性能相近。问题是用金刚石修整普通砂轮是一种经济有效的工艺,没有 First, review In 1989, Indian scholars first invented the use of laser trimming ordinary SiC and Al 2 O 3 grinding wheel, in their experiments, the first dressing with diamond grinding wheel, and then ordinary pulsed YAC laser vertical irradiation of the wheel surface, each pulse shot on the wheel surface A small hole, through relative motion, partially overlaps the small pits to obtain the surface of the laser-trimmed grinding wheel. The grinding tests show that the grinding performance of the laser-trimmed and diamond-trimmed grinding wheels is similar. The problem is diamond dressing ordinary grinding wheel is a cost-effective process, no
