Isn’t the cutting tool used in the machining center as fast as possible? Why need to passivate it? In fact, cutting tool passivation is not a literal meaning to everyone, but a way to increase the service life of the tool.
Improve tool quality through smoothing, polishing, deburring and other processes. This is actually a normal process after the tool is ground and before the coating.
What is tool passivation?
By deburring, smoothing and polishing the tool, the tool quality and service life are improved. After the tool is finely ground and before the coating, its name is not uniform at home and abroad at present. It is called “edge passivation”, “edge enhancement”, “edge honing”, “edge preparation” or ” ER (Edge Radiusing) processing “and so on.
Why is cutting tool passivation necessary?
Modern high-speed cutting and automated machines place higher requirements on cutting tool performance and stability, especially coated tools must be passivated by the cutting edge before coating to ensure the firmness and service life of the coating.
Purpose of cutting tool passivation
The purpose of the tool passivation technology is to solve the defect of the micro-notch of the cutting edge of the tool after sharpening, so as to reduce or eliminate the sharpness, and achieve the purpose of smooth and flat, sharp and strong and durable.
