通过了解金属冷热切圆锯片的使用状况以及现有锯片刃磨机的使用效果,找出了径向磨削式锯片刃磨机存在的问题和不足,分析了锯齿修磨质量差、锯切寿命低的主要原因。按照新的思路设计了轴向磨削式锯片刃磨机,经应用证明,可以明显改善锯齿刃磨质量,延长锯片使用寿命,具有良好的推广价值。 By understanding the use of metal hot and cold circular saw blades and the use of existing blade sharpening machine to find out the problems and deficiencies of the radial grinding saw blade sharpener, analysis of poor quality of serrated grinding , Sawing the main reason for low life. In accordance with the new idea designed axial grinding blade saw grinder, the application shows that can significantly improve serrated grinding quality, extend the life of the saw blade, has a good promotional value.
