Tungsten Carbide Cutting Tools Edge Passivation Importance

The extremely sharp and smooth enough neat tungsten carbide cutting tools edge machining to have a specific, smooth shape, and edge rounding mostly waterfall edge, this process is called edge passivation. China is a big manufacturing country, continuous consumption of tungsten carbide cutting tools in the world, however, the domestic production of tools, as compared with the import tool in terms of performance and life, there is a big gap. CNC machine tools used in the production line or from abroad, which have all been passivated edge, greatly reducing the cost of the tool, but also brought huge economic benefits.

Tungsten carbide cutting tools material, geometry, structure and cutting the amount of influence and decision tool life. Good tungsten carbide cutting tools edge passivation types and can also improve the quality of life of the tool. Therefore, the situation is good or bad is the tool edge can not be ignored. With the improvement of the accuracy of the tool, stability requirements, and its importance will be more prominent. The passivation process is the elimination of edge defects in the cutting edge of the cutting edge and the passivation process, can improve the stability of the cutting tool, the tool to increase reliability and improve the surface quality. Edge roughness of cutting edge passivation changed the geometry of the cutting tool, cutting edge micro-topography and near the surface of the tool cutting edge. Reasonable edge passivation treatment can increase the strength of the cutting edge, to reduce chipping, eliminate the original defect of the cutting edge, increasing the tungsten carbide cutting tools life, and can provide a good tool for surface coating.
