[0002] In modern manufacturing, machine tools are key equipment for processing various parts, and machine tool cutters are the core components for machine tools to achieve precision machining. Whether it is metal cutting processing, such as turning, milling, drilling, etc., or in the processing of some special materials, the quality and performance of machine tool cutters directly determine the machining accuracy, surface roughness and machining efficiency. After retrieval, the publication (announcement) number: CN220007060U discloses a grinding device for machine tool cutters. By setting a fixing component, the milling cutter to be ground can be firmly clamped inside the fixing groove. At the same time, through the cooperation of the rotating rod, the base, the handle and the fixing shell, the handle can be held to rotate the milling cutter for fine grinding. This device effectively avoids the situation of injury caused by holding the cutter by hand in the past, thereby improving the grinding efficiency. However, there are deficiencies: Although it can avoid the danger caused by the operator holding the cutter by hand, since the base is rotatably connected to the operating table and cannot be moved well, all sides of the cutter cannot be ground when grinding the cutter. Therefore, it is very likely that the accuracy of the cutter cannot be guaranteed, and the cutter has too low grinding accuracy, resulting in unqualified workpieces processed.
