What are the causes of blade wear in cutting? How to deal with it?（II）
Tipping
The part of the cutting edge that is not involved in the cutting is damaged by a chip hammer. The front and support surfaces of the blade are damaged, resulting in poor surface texture and excessive wear of the rear blade surface
Reason:
The chip is compressed under the action of the cutting edge
Solution:
* Choose a brand with higher toughness
* Choose a blade with a stronger cutting edge
* Improve cutting speed VC
* Select the front Angle groove
* Reduce feed at the beginning of cutting
* Improve Dimensional Stability
Groove wear
Trench wear results in poor surface quality and cutting edge fracture risk
Reason:
* Work hardening material
* Epidermis and oxide skin
Solution:
* Reduced cutting speed (VC)
* Choose a brand with higher toughness
* Use a stronger groove
* Use a cutting Angle closer to 45°
* Use a round blade to ensure best results
* Delay wear using variable AP technology
Built-up edge
The filamentous tumor results in poor surface quality and breaks the cutting edge when detached
Reason:
* The cutting area is too cold
* Materials such as mild carbon steel, stainless steel, and aluminum are highly viscous
Solution:
* Increase cutting speed
* Switch to a more suitable blade groove
