Reasons for the fracture of cutting piece
In the process of using the cutting piece, sometimes it will encounter the phenomenon of cutting blade fracture. What is the cause of the fracture? I think it is necessary to talk with you, so that we can try to avoid this situation in the future use of the process, less waste of some unnecessary time, to avoid some of the security risks.
The main reasons causing the cutting pieces are as follows:
1, the cutting chip itself has the quality problem, such as the cutting of the plane of the cutting, the organization of the cutting blade, the high hardness of the cutting blade, the lack of toughness of the cutting blade.
2, the operation method is not correct, such as cutting the line speed is only 72m/s, and the operator will cut the piece to install online speed to reach 80m/s cutting machine.
3, careless, cutting film into a grinding machine used to idle (there is no workpiece operation) a minute. This process can detect cutting quality and cutting piece aperture and cutting table shaft is equipped with.
4, the use of the cutting blade after a more serious collision, although it is relatively complete on the surface, but its internal structure has been damaged, such a cutting piece in the work is also more prone to fracture.
