3 Axis vmc milling cutters often choose the spring clamp set clamping method, and they are in a suspended state during use. During the machining process, sometimes the end milling cutter may slowly extend from the tool holder or even fall. , Resulting in damage to the workpiece.
We provide suggestions for the attention points of the end mill: 1. When the diameter of the end mill is large, for the possibility of tool drop, we can choose the method of locking the corresponding side surface of the tool holder with a flat notch! 2. End-mill end-cutting molds and other workpiece cavity CNC milling processing, when the cut point is a concave part or a deep cavity, the extension of the end mill needs to be lengthened. If a long-edged end mill is used, because the tool has a large deflection, it is easy to oscillate and cause the tool to break. Therefore, in the machining process, if only the end of the tool needs to be adjacent to the cutting edge to participate in cutting, it is best to choose a long-shank end mill with a longer total tool length and a short edge. When large-diameter end mills are used on horizontal CNC machine tools to process workpieces, due to the large deformation of the tool's own weight, it is necessary to pay close attention to the problems that are prone to edge cutting. If a long-edged end mill must be used, the cutting speed and feed rate must be drastically reduced.
