研磨条件和材料组织结构对硬质合金刀尖状态的影响

Influences of Grinding Condition and Material Texture on Point Appearance of Cemented Carbide Cutting Tools

为探讨硬质合金刀具的研磨特性,对8种硬质合金刀片研磨后的刀刃状态进行了对比试验研究,提出利用刀尖附近切削刃的微特征及参数来综合评价薄层切削刀具的修磨质量,并分析了研磨条件和材料金相组织对刀尖状态的影响。

In order to inquiry into the grinding characteristics of cemented carbide cutting tools, the ground point appearances of eight kinds of cemented carbide inserts are investigated by contrast test. It is put forward that the grinding quality of fine cutting tools can be evaluated comprehensively with micro-features and parameters of the blade near point, and influences of grinding condition and material texture on the point appearance are analyzed.
