How to solve the problem of beading movement of diamond rubber wire saw?

Diamond wire saw often has a situation in the cutting process: beading movement. Beading movement refers to the phenomenon that the rubber cannot support the beads, and the beads are moved on the steel rope. The specific performance is as follows:

1: The beads move and rotate while diamond wire saw is cutting, and the beads can be rotated clockwise or counterclockwise at will. The tightness during the rotation determines the rotation speed of the beads, and also reflects the severity of the beading movement.

2: The beading will cause friction to the surrounding rubber during the cutting process, and the extent of the beading movement and the scope of the wire rope back and forth will increase.

3: The beading movement not only does not produce any value during the moving process, but with the increase of cutting time, the moving beads will continue to cut the wire rope. The most serious situation is that the beads cut the wire rope off , which eventually leads to the occurrence of diamond wire breakage.



4: The most serious situation of beading movement is that all the beads are loose,leading to the wire saw can not cut at all, which becomes a waste wire saw.

The main reasons for the occurrence of beading movement are as follows:

1: The adhesion between the rubber and the steel rope is not enough. So the beads are loose, and the beads are crowded together under the load. The insufficient adhesive force of the rubber is also manifested in the insufficient fixing force to the beads. At the beginning of the work, the rubber and the beads are separated, and the separated rubber and beads work separately. The life and efficiency of such a wire saw are greatly reduced during the cutting process. There are actually many reasons for this situation: such as rubber material problems, glue injection process problems, diamond wire saw storage problems and so on.

2: Dry grinding occurs, and the rubber melts and loses its bond at high temperature. The main reason for that is that the amount of cooling water is small, which leads to the dry cutting of the wire saw during the cutting process. This situation will cause the temperature of the beads to rise rapidly, and the rubber will melt due to such high temperature. As the temperature drops in the later stage, the rubber on the wire saw gradually loses its cohesiveness. During the cutting process, cracks will appear in the rubber and the beads, which will lead to the occurrence of beading movement.

3: When the wire saw breaks, the wire rope is thrown out and hits other objects, causing beads to rotate and move. This kind of situation is relatively rare. The main reason is that the beads have received a very strong impact, resulting in cracks in the beads and the rubber. Under normal circumstances, this situation seldom occurs.

4: If the quality of the wire rope is too poor, the wire rope will be deformed , especially elongated under the condition of high current and high power which make the tension of the wire saw is too large. The rubber on the outside of the wire saw is the first to become longer following the length of the wire rope, especially the part connected to the bead. Because the connection surface between rubber and wire saw beads is small, it is also the easiest to crack.

5: The beading movement is caused by the problem of the rope stuck. When cutting hard granite, it is easy to encounter the problem of the wire saw stuck. If it is not handled in time When the wire saw is stuck, some cracks will appear, resulting in the occurrence of bead channeling. The damage to the wire saw is relatively large, especially in the connection parts of beads and rubber.



In the process of wire saw cutting, too low cutting efficiency and too slow cutting speed will also cause the beads to move. In general, beading movement is a common wire saw failure.

In terms of raw materials, there may be some problems with rubber, steel wire rope, and beads, or there may be some problems in the process like sintering process, glue injection process, etc., or there may be some problems in the actual operation during use and operation site, such as stuck rope, Broken rope, etc. The solutions mainly include choosing a more stable wire saw brand, choosing a wire saw with higher cutting efficiency, and doing frequent inspections during the cutting process, observing the running status of the wire saw all the time, and constantly adjusting the cutting status to avoid wire saw cutting. These measurements will avoid the wire saw failure of beading movement.
