The sharpness of the diamond segment is mainly reflected in whether the segment can cut the stone and the efficiency of the segment in cutting stone. The former determines whether the segment can meet the basic cutting needs, while the latter is more reflected in the speed of cutting efficiency. Since most of the content involved in the former is formula, this article will not introduce too much, but mainly introduce the second situation: how to improve the cutting efficiency of the segment?

There are many ways to improve the cutting efficiency of the segment. Almost all production processes and links will affect the sharpness of the segment. Usually  from the following aspects to adjust the segment sharpness.

1: From the diamond aspect

If the cutting speed of the segment is slow, first it can be adjusted from the concentration of the segment. If the segment has a long service life but the sharpness is not high, then appropriately reducing the diamond concentration in the segment; if the life of the diamond is short, and the sharpness is not enough. At this time, it can be considered whether the diamond concentration is somewhat insufficient. Appropriately increasing the concentration can improve the grinding force of the segment, which can also appropriately increase the sharpness of the segment.

Secondly, if in the process of cutting, the segment is not easy to open, and the grinding force is insufficient, which is mostly caused by the insufficient strength and the insufficient grade of diamond powder in the diamond segment, and it needs to be replaced with higher strength and the grade of diamond powder, this can significantly improve the cutting efficiency of the diamond segment.

Finally, if during the cutting process, the segment has obvious trailing, but the sharpness is not high, this situation is mainly caused by the  diamond particle size is too small, then properly increasing part of the diamond particle size can significantly improve the problem.

2: From the carcass aspect

First of all, if the segment has obvious opening appearance, but the service life is very short and the cutting efficiency is not high, then the problem is caused by the soft carcass, and the hardness of the carcass needs to be adjusted in time. Secondly, if the segment is ground flat, then the segment in cutting the stone, it will cause the segment to be slip, this is mostly caused by the too hard carcass.

3: The production process causes problems with the sharpness of the segment

It is very important to control the temperature and pressure during the sintering process of the segment. The temperature control also includes the heating time, the holding time, and the pressure control also includes the pressing time and the holding time. If there are obvious problems in these processes, the segment will face more or less problems, which are directly reflected in the sharpness, that is, the cutting efficiency is low. To change this situation, special attention must be paid to production control.

4: Other issues


First of all, welding has a great influence on the sharpness of the diamond segment, and stable welding can speed up the cutting efficiency of the segment. Secondly, the shape, thickness, length and spacing of the segment will affect the sharpness of the segment. Generally speaking, the W-shape, the narrower the thickness, the shorter the length, and the wider the pitch, the sharper of the segment will increase. Finally, the sharpness of the segment is also affected by the structure. The segment with layer structure is generally sharper than the sandwich segment, and the more layers, the higher the sharpness.
