Tungsten Carbide Milling Problems and Solutions

When tungsten carbide milling cutter, the inevitable always a wide variety of problems. These problems generally include tool breakage, wear, short tool life (edge passivation), blade gap, chip stacking, edges, no vertical edge, size is not enough precision, noisy and rough surface fine milling and other phenomena. Carbide tool breakage occurs reasons generally feed too fast, chip volume is too high, the total length of the blade length is too long or too long, such as excessive wear, the solution is to reduce the feed rate, lower feed per tooth to the rate fixed shank deep; use shorter end mill, early grinding. Reason for the occurrence of a short life of tungsten carbide cutting tools (knife edge passivation) is generally too high friction when cutting the workpiece and tough or incorrect cutting angle, its grinding solutions for the early use of advanced tool steel (metal polymer molecules ) or switch to the correct cutting angle and clearance angle.
