摘要: 采用真空射频溅射的方法制备涂层微磨具,探讨了微磨具表面涂层制备机理,针对黄铜材料进行涂层微磨具的磨削表面质量实验研究,分析不同加工工艺参数和因素对涂层微磨具磨削表面性能的影响规律.实验结果表明,随着不同涂层微磨具磨削速度的增大,磨削深度和进给速度的减小,黄铜表面粗糙度呈现减小的趋势,表面形貌更加光滑,表面质量更好;在相同的磨削工艺参数下,与未涂层微磨具相比,涂层微磨具的磨削力值更低;相同粒度的涂层微磨具和未涂层微磨具比较,涂层微磨具表面粘结磨屑现象得到改善,在一定程度上增加了涂层微磨具的使用寿命.

Abstract: Coated micro-grinding tools were prepared by vacuum radiofrequency(RF) sputtering. The preparation mechanism of surface coating of micro-grinding tools was discussed. The grinding surface quality of coated micro-grinding tools was experimentally studied for brass materials, and the effects of different processing parameters and factors on the grinding surface properties of coated micro-grinding tools were analyzed. The experimental results showed that with the increase of grinding speed and the decrease of grinding depth and feed speed, the surface roughness of brass shows a decreasing trend, the surface morphology is smoother and the surface quality is better. Under the same grinding process parameters, the grinding force of coated micro-grinding tools is lower than that of uncoated micro-grinding tools. Compared with uncoated micro-grinding tools, coated micro-grinding tools with the same particle size can improve the surface adhesion of wear debris, and increase the service life of coated micro-grinding tools to a certain extent.

Key words: coated micro-grinding tool; surface roughness; grinding force; surface morphology; surface quality
