有序排布钎焊金刚石磨盘的实验研究

Study on orderly arranged brazing diamond millstone disc

将有序排布理论运用到钎焊技术,成功制备适合黑色金属、钢铁材料磨拋的新型工具—有序排布单层钎焊金刚石磨盘;将平面单颗磨粒有序排布方式与磨料群可控排布方式相结合,设计出一种新型磨盘顶端平面排布方式,并确定排布参数;对船用钢板Q345低合金高强度结构钢进行磨拋试验,对比分析新型钎焊金刚石磨盘与传统树脂砂轮片的磨削性能。结果表明:新型磨盘较树脂砂轮片噪音提高,磨屑规则(主要呈带状),磨粒以磨损失效为主,几乎无整颗磨粒脱落,磨削效率约为树脂砂轮片的1.5倍。

We applied orderly arrangement theory to brazing technology and successfully made the orderly arrayed monolayer brazing diamond millstone for polishing ferrous metal, steel and iron material.Plane single abrasive orderly arrangement way was combined with abrasive group of controllable configuration mode and a new configuration mode was designed for millstone top plane of optimized the configuration parameters.Polishing experiments were done on Q345 high strength low alloy structural steel used in ship.By contrastive analysis of the grinding performance between the new brazing diamond millstone and traditional resin grinding wheel,the results turned out that the new millstone had a higher noise than resin grinding wheel piece and its abrasive dust is regular and banding. Wear failure was the main failure type and almost no whole grinding grain fell off.The grinding efficiency of new millstone was one point five times than that of resin grinding wheel.
