Why Do CNC Cutting Tools Need to be “Passivated”?

Tool “passivation” is a process of micro-processing the cutting edge of the tool. The purpose is to remove tiny burrs and irregularities on the cutting edge. Or the sharp cutting edge is moderately rounded to improve the performance of the tool. This treatment does not actually make the tool blunt, but makes the cutting edge
