Abstract (in Chinese)
硬質合金是目前常見切削刀具材料之一,其具有高硬度、高耐磨性及優異的切削性能。但因為這些特性使硬質合金的加工不易,目前多用樹脂砂輪以研磨方式進行加工,但為了提升研磨效率,許多工廠選擇加重進刀量研磨硬質合金,這會產生更多的研磨熱而造成砂輪磨耗過快。本研究使用不同耐高溫樹脂作為結合劑,製作耐高溫樹脂砂輪,在硬質合金工件上進行研磨實驗,明顯改善砂輪磨耗量。
Abstract (in English)
Cemented carbide is one of the common cutting tool materials, which has high hardness, high wear resistance and excellent cutting performance. Because of these characteristics, the machining of cemented carbide is not easy. At present, most of them are processed by grinding with resin grinding wheels. However, in order to improve the grinding efficiency, many factories choose to increase the feed rate to grind the cemented carbide. This will generate more grinding heat and cause the wheel to wear fast. In this study, different high temperature resistant resins were used as binders to make high temperature resistant resin bond grinding wheels, and grinding experiments were performed on cemented carbide, which significantly improved the wheel wear.
