Cutting edge cutting technology of end mill

End mill cutting edge cutting technology, end mills in the mold and other parts of the cavity of the CNC milling process, when the cutting point for the concave part or deep cavity, the need to increase the amount of extension of the end mill. If you use long-edge type end mills, due to the larger deflection of the tool, easy to produce vibration and lead to damage to the tool. Therefore, in the processing process, if only the end of the tool edge of the blade to participate in cutting, it is best to use a long total length of the long knife long knife type end mill. In the horizontal CNC machine tools using large diameter milling cutter processing of the workpiece, due to the deformation of the tool itself caused by a large deformation, should pay more attention to the edge cutting edge prone to problems. In the case of long edge type end mills, the cutting speed and feed rate must be drastically reduced.
