Factors affecting the life of the cutting tool, here generalized three factors of the cutting tool itself, which include material for the tungsten carbide steel cutting tools, coating for the cutting tools, and the dimensions of cutting tools, let’s discuss them one by one.

Factors affecting the life of cutting tools – Cutting tools Itself factor

1. Material of tungsten carbide steel cutting tools
Tungsten carbide steel is very hard and is often used as a material for cutting tools. Tungsten carbide steel itself contains carbon, tungsten, cobalt and other alloy material to increase its properties.

2. Coating for the cutting tools
A film is formed on the surface of the cutting tool by chemical or physical methods, so that the cutting tool can obtain excellent comprehensive cutting performance to meet the cutting requirements. Compared with uncoated cutting tools, coated cutting tools have significant advantages: they can greatly improve the life of cutting tools; effectively improve the efficiency of cutting. Improve machining accuracy and significantly improve the surface quality of the workpiece being machined; effectively reduce tool material consumption. Due to the advancement of modern technology, more coating technologies have been developed for application to cutting tools. It can be used according to the material and characteristics of the workpiece to be processed.

3. The dimensions of cutting tools
According to the shape and dimensions of the machined workpieces, the types and specifications of the cutting tools required are different. The machining application must be considered to select the right cutting tool, if you choose the dimension of the cutting tool that is not suitable, it may cause the vibration during the machining process, the interference of the machining process, the cracking of the cutting tool tip, the rapid wear of the cutting tool tip, and the wrapped tip of the cutting tool.

Conclusion

Whether it is a test cutting tool for a new project or a cutting tool for an improvement developing, the above three factors need to be considered. Follow-up is to do a good job of cutting tool life recording in order to find the best cutting tool conditions and be satisfied with the life of the cutting tool. Other factors that affect the life of the cutting tool will be introduced in the other blog topics.
