高速、超高速磨削与超硬磨料砂轮及其修整的研究

Study on High-speed & Super-high Speed Grinding and Superabrasive

论述了高速、超高速磨削的发展现状及其关键技术 .介绍了国际上制备单层钎焊超硬磨料砂轮新技术 ,设计了一套在线闭环控制系统 ,以声光调QYAG激光烧蚀修整超硬磨料砂轮 ,并进行了试验 。

This paper deals with the development situation and key technique of HighSpeed & Super-high Speed Grinding and introduces an international new manufacturing technology of brazed monolayer superabrasive grinding wheel.An online closed loop control system for dressing superabrasive grinding wheel is designed. The experimental results show that it is a practical, convenient and effective method to use opto-acoustic Q-switched YAG laser for trimming.
