The factors influence the life of cutting tools

The following factors influence the life of cutting tools:

1.Cutting tool coating

By using chemical or physical methods, a thin film is formed on the surface of the cutting tool, allowing the tool to achieve excellent, comprehensive cutting performance to meet the cutting requirements. Coated cutting tools have obvious advantages over uncoated cutting tools: they can significantly increase cutting tool service life, effectively improve cutting efficiency, improve machining accuracy, significantly improve the surface quality of the workpiece to be machined, and effectively reduce tool material consumption. More coating techniques for use on cutting tools have been developed as a result of advances in modern technology. It can be used depending on the material and properties of the machined workpiece.

2.Cutting tool dimensions

The type and size of cutting tools required will vary depending on the shape and size of the workpiece to be machined. The machining application must be considered when selecting the right cutting tool. If an inappropriate cutting tool size is chosen, it may cause vibration during machining, disturbances in the machining process, a cracked cutting tool tip, rapid wear of the cutting tool tip, and cutting tool tip failure. 

3.The material of tungsten carbide cutting tool

Tungsten carbide steel is a very hard material that is frequently used to make cutting tools. To improve its properties, tungsten carbide steel contains carbon, tungsten, cobalt, and other alloy materials.
