Diamond segments is used to process hard materials, For example, for cutting stone, welding the segments of the corresponding specification and size on the base of the saw blade, When the saw blade rotates quickly, the diamond segments quickly grinds the stone surface. Grind softer stone by the hardness of diamond, Finally, the stone is cut in this way, Among them, in the grinding process, the grinding speed, that is, the cutting speed and the cutting depth are very important parameters, and the sharpness of the diamond segment is reflected in these two parameters.

What is the sharpness of the diamond segment? When the diamond segment and the hard material are violently rubbed, The grinding area per unit time directly determines the sharpness of the diamond segment. Based on this theory, the following conclusions can be drawn. The grinding area is equal to the walking speed multiplied by the following knife depth, and then multiplied by the running time. When we set the time to a constant value, the larger the grinding surface value, the higher the sharpness of the diamond segment, and vice versa, the lower the sharpness of the diamond segment. The formula is as follows: S=s(cutting speed)*d(cutting depth)*s(fixed running time).So what kind of segment has high sharpness? The diamond segments with good sharpness has the following characteristics:

1: The hardness of the diamond segments is slightly higher than that of the stone, not too high, not too low, It is because if the hardness of the diamond segments is too high, the hardness of the bit binder is higher, There will be a lot of work in the carcass binder. Since the bond binder does not have cutting performance, too much participation in cutting will greatly slow down the diamond cutting ability; However, if the hardness of the diamond segments is too low, the diamond will not be fully consumed, and the cutting efficiency will be greatly reduced.

2: The diamond has higher grade requirements, When cutting diamond is the core part of the diamond segments, There are many grades that are normally used to make synthetic diamond cutter heads. Generally, we choose 4, 6, and 8 grades. Most manufacturers also choose grade 6 diamonds, but in order to save costs, many people like to add some grade 4 and grade 8 diamonds when mixing raw materials. Experimental tests have shown that if some grade 8 diamonds are added, the cutting performance and sharpness of the diamond segment will increase. On the contrary, if some grade 4 diamonds are added, the sharpness of the diamond segment will decrease.

3: The diamond grinding efficiency also needs to be determined according to the number of diamond opening. The number of diamond opening is actually related to two factors: Diamond concentration and diamond particle size, For cutting marble, using low-concentration, large-grain diamonds can greatly improve the grinding efficiency of the segments; for cutting granite, using high-concentration, small-grain diamonds can greatly increase the segments The sharpness.

4: In addition to the above factors, In fact, there are many processes in the manufacturing process of the segments, For example, the sharpness and life of the orderly segments have been greatly improved compared with the traditional segments. In terms of shape, the sharpness of the corrugated segments is much higher than that of the ordinary one.

In general, the sharpness of the diamond segments is determined by the hardness and abrasiveness of the cutting object. Then it is equipped with a better grade diamond, reasonable particle size and concentration, and a better shape to better improve the sharpness of the segments.

In fact, the factors that increase the sharpness of diamond blades are much more than that. The blank blade, the machinery used for cutting also has a great influence on the improvement of sharpness.
