Three Factors Affecting the Life of Cemented Carbide Cutting Tools

Cemented carbide tools have a wide range of applications in the industrial market, and their excellent properties are favored by customers. So, do you know what factors affect the life of cemented carbide tools? Please allow Betalent to answer this.

The service life of cemented carbide tools is generally affected by three aspects. They are the preparation of the tool substrate, preparation of the cutting edge, and the choice of coating.

1. The tool substrate of cemented carbide tools

The particle size of WC can determine the substrate properties of cemented carbide tools. The larger the particle size, the stronger the toughness of the tool. The smaller the particle size, the better the wear resistance of the tool. The cobalt content of the tool can also be controlled at 6%~12% to obtain good toughness.

2. Preparation of the cutting edge of cemented carbide tools

The preparation of the cutting edge of cemented carbide tools is also called edge passivation, which is an important factor affecting the success or failure of machining.

Generally used for continuous turning and milling of most steel and cast iron inserts, a greater degree of cutting edge passivation is required.

On the contrary, the blades used for processing stainless steel and high-temperature alloys are prone to form built-up edge, so the cutting edge is required to be sharp and can only be slightly passivated.

3. The choice of coating for cemented carbide tools

The coating can improve the cutting toughness of cemented carbide tools to a certain extent.

Coating technology includes: titanium nitride coating, nitrogen aluminum titanium coating, titanium carbonitride coating, chromium nitride coating, diamond coating and so on.

Betalent can have high-quality tool substrate, coating and mature cutting edge preparation technology, and customize sophisticated carbide tools for customers.
