Grinding process is an important machining technique,and it has a wide range of applications in precision machining and ultra-precision machining.The wheel is a widely using tool in the grinding process,but the conventional wheel exists high specific grinding energy and temperature rise,high ratio of normal to tangential grinding forces,and the abrasive can fall off by grinding forces in the process.Moreover,grinding wheel wear and loading problems becomes more sever when grinding sticky materials,which requires more frequent wheel truing and dressing.This paper discussed the state-of-the-art and the achievements of the grinding wheels,and analysed the features and shortages of some new types wheels,such as brazed monolayer wheels,fiber wheels,slotted grinding wheel,soft wheels,porous grinding wheels and grinding wheels with controlled distributing abrasive,and the future perspectives in grinding wheels were also

studied.
