There are many occasions where cutting tools need to be used in our daily lives, so cutting tools wholesale can be seen in many places. However, in cutting, what is the main reason for tool wear caused by mechanical action and thermochemical action?
Tool wear is mainly caused by mechanical action and thermochemical action. The main cause is diffusion wear. Under high-temperature conditions (850~1000℃), elements such as Ti, W, Co in the tool material will gradually diffuse into the workpiece or chips, and the Fe element in the workpiece material will also diffuse to the surface of the tool. In this way, the chemical composition of the tool material is changed, and its hardness and wear resistance are reduced, thereby intensifying the wear of the tool.
Of course, this is only one of the points, and several other aspects may also cause tool wear. In short, there are many reasons for tool wear. Under different tool materials, workpiece materials, and cutting conditions, the causes of tool wear are different, which may be one of them or the result of a combination of several of them.
