Tungsten Carbide Cutting Tool Chipping Causes and Solutions

Use tungsten carbide cutting tools may appear chipping phenomenon occurs chipping a variety of reasons, reasons that may occur are: insert grade, specification poor choice. If the thickness of the blade is too thin, or too hard when roughing selected grades too brittle. Its solution: increase the thickness of the blade or blades mounted upright, bending strength and high toughness selection of brands; tungsten carbide tool geometry parameters properly (such as before and after the angle is too large, etc.). Its solution: You can proceed from the following aspects of the redesign of tungsten carbide cutting tools: (1) appropriate to reduce the front and rear corner; (2), the use of large negative edge inclination; (3) to reduce the main angle ; (4), using the large negative edge chamfer or arc; (5), grinding the cutting edge transition, enhanced tip.
