Carbide insert is a cutting tool made of carbide material. It has the characteristics of high hardness, high strength, high wear resistance and high corrosion resistance, so it is widely used in the cutting processing of various materials. The following is a detailed introduction to the cutting principle of carbide inserts:
- Preparation before cutting: Before cutting begins, the carbide insert needs to make contact with the workpiece first and establish the initial pressure between the cutting edge and the workpiece surface. This initial pressure is an important factor in the cutting process, which can promote the cutting process.
- The beginning of the cutting process: When the initial pressure between the cutting edge and the workpiece surface reaches a certain value, the material on the workpiece surface will gradually deform, and chips will gradually be separated under the action of the cutting edge. During this process, severe friction occurs between the cutting edge and the workpiece surface, resulting in plastic deformation of the workpiece surface material and the generation of chips.
- Chip discharge: Due to the high strength and hardness of the carbide blade, the chips will be quickly extruded, deformed and discharged under the action of the cutting edge. This rapid discharge process can reduce the friction between the cutting edge and the workpiece surface, reducing cutting heat and tool wear.
- Continuation of the cutting process: During the cutting process, the carbide insert will continue to maintain its strength and hardness, and constantly update the position of the cutting edge, so that the cutting process can continue. At the same time, due to the good wear resistance and corrosion resistance of cemented carbide, the blade can also maintain a long-term cutting effect.
- End of the cutting process: The cutting process ends when the cutting edge wears out or the workpiece is machined to the required size. At this point, the carbide insert is removed from the workpiece surface and the machined surface of the workpiece is given the desired finish and precision.
It should be noted that the cutting principle of carbide inserts is different from other inserts. Its high hardness and high wear resistance allow it to maintain long-term cutting results, while also being able to withstand high temperatures and pressures. However, due to the high price of carbide blades and relatively large maintenance costs, the specific processing needs and cost control need to be considered when choosing to use them.
