Abstract


The rapid development of electronic communication technology and the popularity of a large area to the ferrite industry brought significant opportunities . The fast increase of the level of information technology , precision machining of ferrite devices with new challenges. The ferrite efficient production and precision machining problems to be solved . In view of this, we completed the ferrite grinding tests under different grinding conditions to explore the ferrite of high - precision processing pathway . Of this work include : ( 1) the use of resin bond diamond wheel grinding test of ferrite , ferrite grinding quality is evaluated based on surface roughness ; analysis of the iron- oxygen surface morphology the material of the removal system . Indentation fracture mechanics model clarifies the grinding mechanism of the ferrite . (2) using graphite wheel grinding tests conducted ferrite . Studies grinding force , surface roughness , material removal rate and surface morphology with the variation of the process conditions . The analysis showed that the graphite wheel grinding ferrite achieve a high surface quality . (3 ) In order to effectively control the single grain Qiehou precision grinding formulate orderly arrangement monolayer brazing diamond grindstone production process to prepare large particles of diamond brazed wheel designed monolayer brazing diamond wheel dresser device , and monolayer brazed diamond grinding wheel dressing. Analysis of grinding wheel , abrasive high monolayer brazed diamond wheel dresser . ( 4 ) of monolayer brazed diamond grinding wheel ferrite were studied . The research results show that the large abrasive monolayer brazed diamond grinding wheel ferrite surface roughness up Ra0.8μm .
