Abstract： The performance of printed circuit board （PCB） micro drill precision CNC high-speed grinding equipment at home and abroad was analyzed and compared. The main categories of PCB micro drill precision CNC high-speed grinding equipment were introduced. The key structures PCB micro drill precision CNC high-speed grinding equipment and their research status were analyzed. The development trend of PCB micro drill precision CNC high-speed grinding equipment in the future was put forward. The precision， stability， and efficiency of domestic precision CNC high-speed grinding equipment for making micro PCB drill（diameter below 0.2 mm） are still far behind those of imported equipment. The gap is mainly reflected in themulti-station structure， spindle， and grinding wheel. Therefore， it is urgent to ensure the reliability and stability of the spindle and the performance of the grinding wheel to solve the difficulties of PCB micro drill precision CNC high-speed  grinding  equipment. PCB  micro  drill  precision  CNC  high-speed  grinding  equipment  mainly  includes  cylindrical  grinding equipment and cutting tool grinding equipment. The influence on the performance of CNC grinding equipment and their research status of multi-station structure， grinding wheel， spindle system， and feed system were described in detail. In the future， PCB micro drill precision CNC high speed grinding equipment will develop towards high stability， high efficiency， integration， intelligence， and online monitoring and condition monitoring.
