ABSTRACT: The current situation and characteristics of superabrasive wheels dressing are recommended in this paper. Keys of superabrasive wheels dressing and dressing problems to be solved are presented. A promising dressing technique laser Dressing is emphasized. Study on Laser Dressing at home and abroad in recent years has been analyzed Dressing experiments are made on resin-bonded CBN wheels with opto-acoustic Q-switched YAG Laser A conclusion is made that opto-acous-tic Q-switched YAG Laser is adaptive to dress rosin-bonded CBN wheel prospects of Laser Dressing on superabrasive wheels in the future are as follows: establishment of thermohydrodynamice model; improvement on study of dressing mechanism; implementation of laser truing and dressing simultaneously; deep study on Laser Precision Dressing; development of Laser profile dressing; development of adptive controlled dressing system; implementation of on-line Laser Dressing and improvement of dressing efficiency.
