摘要
钎焊金刚石砂轮具有磨粒结合强度高、出刃高、不易堵塞等优点。但细粒度钎焊金刚石砂轮的制备还存在难点。文章提出了一种钎焊金刚石微刃砂轮的制备方法:使用脉冲激光在有序排列钎焊金刚石砂轮表面加工出微刃结构,并研究了钎焊微刃砂轮加工70%SiC体积分数的AlSiC复合材料的磨削性能,对比了钎焊金刚石微刃砂轮和普通钎焊金刚石砂轮在不同磨削参数下的磨削力。研究发现,钎焊金刚石微刃砂轮的磨削力比普通钎焊金刚石砂轮的小;通过观察被加工材料的表面微观形貌,相比普通钎焊砂轮,钎焊金刚石微刃砂轮可以获得更好的AlSiC复合材料磨削表面质量。
The brazed diamond grinding wheel has advantages of high bonding strength of diamond grain and high protrusion without clogging in grinding.However,there are difficulties in the preparation of fine-grained brazed diamond wheels.The paper proposed a preparation method of brazed diamond grinding wheel contained micro-edges.The micro-edge structure was processed on the surface of the ordered diamond brazed wheel by pulsed laser,and the grinding performance of the wheel on AlSiC composites with 70 vol.% SiC was examined.The grinding forces of brazed diamond wheel with micro-edge and ordinary brazed diamond wheel with different grinding parameters were compared.It was found that the grinding force of the brazed diamond wheel with micro-edges was smaller than that of the ordinary one.With observation of the surface morphology of machined AlSiC,the grinding surface quality achieved by the brazed diamond wheel with micro-edges was better than the one by the normal one.
