Why perform tool passivation?

1. Improve tool life and stability: This is the primary benefit. Passivated tools have significantly increased edge strength, greatly enhancing their resistance to chipping and breakage during cutting. Tool life can typically be increased by 20% to 200% or even higher, resulting in better machining consistency.2. Improve workpiece surface finish: A sharp cutting edge may be too "sharp" during initial cutting, easily causing micro-tears and burrs. An optimized passivated edge can remove material more smoothly, resulting in a better workpiece surface finish.3. Improve cutting process stability: A passivated edge has better impact resistance, effectively reducing vibration and squealing during cutting, making machining smoother, especially crucial for high-speed cutting and machining difficult-to-machine materials.4. Eliminate microscopic defects from previous processes: Whether before grinding or coating, the cutting edge contains microscopic imperfections that are difficult to see with the naked eye. Passivation effectively removes these defects, laying a perfect foundation for subsequent coating treatments. A smooth substrate allows the coating to adhere more firmly and evenly, thereby maximizing the coating's performance.
