End Cutting Of CNC Milling Cutter

In the CNC milling of workpiece cavities such as molds, when the cut point is a concave part or a deep cavity, the extension of the milling cutter needs to be lengthened. If a long-edged milling cutter is used, due to the large deflection of the cutter, it is easy to vibrate and cause the cutter to break. Therefore, during the machining process, if only the cutting edge close to the end of the tool is involved in cutting, it is best to use a short-edge, long-shank milling cutter with a longer total 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, special attention should be paid to the problem of excellent end edge cutting. When it is necessary to use a long-edged milling cutter, the cutting speed and feed speed need to be significantly reduced.
