Methods and techniques of re-opening diamond segments

Diamond segment is a kind of saw tooth used for diamond saw blades. In practical applications, due to the abrasiveness of the cutting material or the insufficient cutting ability of the saw blade itself, the diamond segment will not be able to cut the stone. By observing the diamond segment part of the diamond saw blade, you will find that the diamond segment is ground flat, and even some diamond tailing is not obvious. At this time, the diamond segment needs to be opened again. The specific cutting method is as follows: The following types:
1: Cutting refractory bricks can re-open the diamond segment.
This method is often used for re-opening saw blades over 300mm, but this method is not suitable for multi-blades. Generally, if the saw blade gradually cannot cut the stone. At this time, the diamond segment is obviously polished, but the height of the remaining diamond segment is relatively high. In order to continue to use this group of old diamond segments, even reducing the saw blade speed can not solve the problem , cutting refractory bricks is a better choice.

The specific operation method is also relatively simple. Through the strong abrasiveness of the refractory brick, the diamond metal bond is quickly consumed, and finally the diamond segment is released. If there is no refractory brick, the problem can also be solved by using stone with high cutting abrasiveness, such as red sandstone with high abrasiveness.

2: Mixed cutting can help the saw blade to re-open.
In many cases, the metal bond of the diamond segment is too hard, and similar situations are easy to occur when cutting soft stones. At this time, there are two solutions, either to replace the saw blade and the diaond segment, or to make the cut stone more diverse through mixed cutting The specific operation is to cut materials with high abrasiveness and low abrasiveness, and alternately cut through the actual performance of the saw blade, which can also solve the problem of re-opening the saw blade.

Do not use the saw blade for cutting granite to cut marble, but use the diamond segment for cutting marble to cut various marble with different hardness. Sometimes the diamond segment suitable for mixed cutting can meet the special needs of some customers. For example, there are many kinds of cutting materials, so this kind of saw blade can be used for cutting processing.

3: Grinding after removing the diamond segment, and finally welding.
There are more serious cutting problems in the cutting process of the diamond segment, such as the problem of deformation of the diamond segment due to lack of cooling water, and the problem of saw tooth deformation of the diamond segment. It's cumbersome, first you need to remove the diamond segment from the base, then grind the diamond segment on the grinding wheel, let the diamond segment out of the edge, and then weld it again. This method can also be removed at intervals and then welded according to the actual situation of the diamond segment, which is mainly used for obvious cutting problems of the diamond segment.

4: Grind the diamond segment directly with a hand-held electric grinder.
In this process, the saw blade needs to be rotated continuously. By grinding the teeth of the diamond segment one by one, the re-opening of the entire diamond segment is finally completed. This method is often used for opening the diamond segment of a large-diameter saw blade, but the working time will be slightly longer.

5: If it is a medium-diameter saw blade, the way of opening is often to use a belt machine to cut the blade, remove the saw blade, and finally complete the opening of the diamond segment through the automatic walking belt machine. Because of the belt machine, relatively few people use this method, but this method of sharpening is the most efficient one.
Generally speaking, re-opening the saw blade is labor-intensive and time-consuming, and it depends on the situation of the saw blade and the consumption of the diamond segment. If the diamond segment is about to be consumed, there is no need to re-open the blade. The focus should be shifted to determine the cause of such a situation on the diamond segment, and avoiding such problems is the best solution.
