Tool wear is very common in machining procedures. Today we will introduce several other types of tool wear.

Thermal cracking is a phenomenon in which irregular deep cracks appear in local areas of the working surface due to thermal stress. When severe cracks occur on the front or back of the blade, it is best to use M series application materials with good thermal conductivity and less prone to thermal fatigue.

Notch. When a relatively large notch occurs along the blade, in order to enhance the impact resistance of the cutting edge, correct the front angle in the negative direction. If changing the blade shape has no effect, choose a material with high toughness.

Abnormal debris. When severe notches occur on the blade due to heat generation, the cutting speed can be reduced or a high-temperature resistant material can be used.

Peeling of built-up edge. In many cases, the cutting edge will be peeled off when the built-up edge is removed from the front. In this case, a large front angle should be selected or the cutting speed should be increased.

Plastic deformation. For plastic deformation of the blade caused by high heat during cutting, materials with low cobalt content and high temperature at high temperatures can be selected.

Flaking. Due to the vibration during cutting, the workpiece material undergoes elastic deformation and peeling occurs at the front. Materials with high cobalt content and good toughness can be selected.

High-performance and high-quality blades can significantly improve tool life and work-piece finish.
