Diamond blade Semi-fixed abrasive grains with large particles and rigid "trap" effect, the machined surface can be prevented from being scratched large particles

In order to alleviate this contradiction, ultra-precision Research Center, Zhejiang University of  polycrystalline diamond  a semi-fixed abrasive grinding processing technology, which is a new type of abrasive, has good processing properties, can effectively solve the problem of the machined surface damage, both processing efficiency and processing quality, efficient precision machining, semi-fixed abrasive synthetic diamond  fixing the abrasive machining abrasive machining and were free to integrate the advantages. In addition, semi-fixed abrasive grinding of large particles have a hard "trap" effect, to prevent large particles of the machined surface is scratched, the paper mainly semi-fixed abrasive grinding "trap" effect of doing in-depth discussion. In the article the use of discrete element modeling semi-fixed abrasive grinding "trap" effect, in the simulation process, both sides of the wall instead of using discrete element generated conical large particles, due to the semi-fixed combination of abrasive grit overall agent is weak, the simulation process into large particles can be abrasive in slowly.
