It is quite dangerous to use the high efficient metal abrasive disc to break, I think it is necessary to talk to you, so that you can avoid this situation in the process of using it later, waste unnecessary time and avoid some safety hazards.
The main reasons for the fracture of the cutting piece are as follows:
1. The cutting piece itself has quality problems, such as poor flatness of the cutting piece, uneven structure of the cutting piece, high hardness of the cutting piece, and lack of toughness of the cutting piece resin.
2. The operation method is not correct. For example, the wire speed of the cutting piece is only 72m/s, and the operator installs the cutting piece on the cutting machine with the line speed of 80m/s.
3. Carelessness, the cutting piece is installed to be idling (that is, there is no workpiece to run) for one minute. In this process, the quality of the cutting piece and the hole diameter of the cutting piece and the cutting table shaft can be detected.
4. Before use, the cutting piece has undergone a more serious collision. Although it is relatively complete on the surface, its internal structure has been destroyed, and such a cutting piece is relatively easy to break during work.
Therefore, we must choose a good quality cutting piece when selecting the cutting piece. The inferior cutting piece is more likely to cause safety hazards, and the cutting piece is recommended to be purchased nearby.
