Roughing End Mills Operational knowledge

In "Roughing End Mills" cavity molds and other parts of CNC milling, when the point of the concave portion is cut or deep cavities, mills need to lengthen the amount of projection. If you use a long blade-type mills, due to the large deflection of the tool, the tool is easy to produce vibrations and cause breakage. Therefore, in the process, if only near the "" participate in cutting edge tool ends, it is best to choose a longer total length of the tool SHORT LONG cutter. When using large diameter end mill horizontal CNC machining a workpiece on the machine, the resulting deformation due to the weight of the larger tool, but great care should end cutting edge prone to problems. In must use "Roughing End Mills" situation, you need to significantly reduce the cutting speed and feed rate.
