The use life of end mill cutter

In other parts of the mold cavity CNC milling, when the point of the concave portion is cut or deep cavities, end mills need to lengthen the amount of protrusion. If you use long-edge-type mills, due to the large deflection of the tool, the tool is easy to produce vibration and cause breakage. Therefore, in the process, if only near the ends of the tool cutting edge to abrasive cutting disc participate, it is best to choose a longer total length Duanren tool shank type end mill cutter. When using large-diameter end mill horizontal CNC machining the workpiece on the machine, the deformation due to the weight of the tool produced by larger, more attention should be very easy to end cutting edge problems. In case you must use the long blade-type milling end mill cutter, you need to significantly reduce the cutting speed and feed rate.

The choice depends primarily on the cutting speed is material workpiece; feed rate depends on the choice of material and milling end mill cutter is the diameter of the workpiece. Some foreign manufacturers end mill cutter drill bits cutting tool parameters with sample selection table for reference. But at the same time cutting parameters chosen by the machine tool systems affected the shape of the workpiece clamping methods and other factors should be adjusted cutting speed and feed rate according to the actual situation.
