End cutting of milling cutter

In the CNC milling process of workpiece cavity such as mold, when the cutting point is a concave part or a deep cavity, it is necessary to increase the extension of the milling cutter. If you use a long-edged milling cutter, due to the large deflection of the cutter, it is easy to cause vibration and cause the cutter to break. Therefore, in the processing process, if only the blade near the end of the tool is involved in cutting, it is best to use a short-edged long-shank milling cutter with a longer tool length. When using a large-diameter milling cutter to process a workpiece on a horizontal CNC machine tool, due to the large deformation caused by the tool's own weight, more attention should be paid to the problem of excessive cutting of the end edge. When it is necessary to use a long edge milling cutter, the cutting speed and feed speed need to be greatly reduced.
