介绍了振动强化抛光用磨块的制备工艺 ,采用绿碳化硅 ( TL)和立方氮化硼 ( JLD)混合磨料与陶瓷结合剂配合 ,经炼泥、成形、干燥、烧结、打磨等粉末冶金的方法制备磨块 ,该类磨块用于不锈钢等材料的工件表面振动强化抛光效果明显 ,抛光表面的表面粗糙度可达 Ra0 .2μm,抛光效率可提高 30 0 % ,对制备其他材料工件振动强化抛光用磨块具有参考价值。
In this paper, the preparation technology of grinding block for vibration intensified polishing is introduced. The mixture of green silicon carbide (TL) and cubic boron nitride (JLD) and ceramic binder is used to make the powder metallurgy by the processes of metallurgy, forming, drying, sintering, Method for the preparation of grinding block, the type of grinding block for stainless steel and other parts of the surface of the workpiece to strengthen the polishing effect is obvious, the polished surface roughness Ra0 .2μm, polishing efficiency can be increased 30%, the preparation of other materials vibration enhancement Polishing block with a reference value.
