由于对金属和非金属材料加工要求的提高，近十年来硬质薄膜的预处理和后处理一直是研究的重要课题。通过减少表面不均匀性来改善刀具性能的主要方法是在涂层之前和/或之后进行额外的机械或化学处理。特别是涂装前的清洗，必须考虑减少预处理的碎屑量，这些碎屑可能会对涂装后的表面质量产生负面影响。增强涂层前后表面形貌的机械处理工艺主要是磨料射流加工或拖曳精加工等几种机械加工工艺。介绍了一种利用弹性结合剂金刚石砂轮对涂层刀具进行前后处理的新工艺。研究了表面不均匀性的去除率、涂层前后表面形貌的影响以及初始刀具表面对涂层粘附强度的影响，以强调这种前后处理的潜力。此外，还提出了一种表征和描述涂层缺陷数量和涂层缺陷面积比例的新方法。
Due to the increased requirements on machining of metallic and non-metallic materials, the pre- and post-treatment of hard thin films has been an important topic in several researches in the past decade. The main improvement in tool properties by a reduction of surface inhomogeneities is reached by an additional mechanical or chemical treatment before and/or after the coating process. Especially the cleaning before coating has to be considered to reduce the amount of debris of the pre-treatment which may negatively effect surface quality after the coating process. The mainly used processes of mechanical treatment to enhance surface topography before and after coating are several machining processes such as abrasive jet machining or drag finishing. This paper introduces a novel process for the pre- and post-treatment of coated cutting tools by elastically bonded diamond grinding wheels. Both the removal rate of surface inhomogeneities, the influence of surface topography before and after coating and the influence of the initial tool surfaces regarding coating adhesion strength were investigated to underline the potential of this pre- and post-treatment. Additionally, a new method for characterizing and describing the number of coating defects and proportion area of coating defects peris presented.
