A new laser conditioning method for micro wheel with ultra fine grit diamond, which are used for the micro grinding of micro grinding of micro-aspherical optics, is proposed. The new laser conditioning method has two stages. The first stage is the high-concentration truing process of micro-wheels. The second stage is the non-contact laser dressing. Generally speaking, the laser dressing is carried out with thermal process. Therefore, it is difficult to apply the laser dressing to diamond wheel. However, third harmonic YAG laser is used in proposed new laser dressing, and dressing is carried out with the ablation process without thermal process. In this research, laser conditioning device is developed and characterization of the laser conditioning is researched. Following results are obtained.1. Number of cutting edge on the micro wheel with ultra fine grit diamond is increased by the new laser conditioning method.2. When a power density of laser is high, the laser, which goes through the diamond, ablates the resin under the diamond abrasive grain. And the diamond abrasive grain fall.3. Titanium coating prevent diamond grains from falling down.4. Laser conditioning device is developed.5. Surface roughness of ground surface is improved by the laser conditioned diamond grinding wheel.

提出了一种用于微非球面光学零件微细磨削加工的超细金刚石砂轮激光修整新方法。新的激光调节方法有两个阶段。第一阶段是微砂轮的高浓度修整过程。第二阶段是非接触式激光修整。一般来说，激光修锐是通过热处理来实现的。因此，激光修锐金刚石砂轮存在一定的困难。然而，三次谐波YAG激光器用于提出的新的激光修整，并进行修整与烧蚀过程中没有热处理。本研究开发了激光调质装置，并对激光调质特性进行了研究。得到以下结果.新的激光修整方法增加了超细粒度金刚石微砂轮的刃口数.当激光的功率密度高时，穿过金刚石的激光烧蚀金刚石磨粒下的树脂。金刚石磨粒脱落.钛涂层防止金刚石颗粒脱落.研制了激光预处理装置.激光修整金刚石砂轮可改善磨削表面的粗糙度。
