The higher the diamond concentration,the better the segment quality?

Diamond concentration is a parameter commonly used in diamond products. The concentration represents the content of diamonds in a diamond tool in a certain volume. Specifically, it refers to the weight of diamonds in a cubic centimeter of segment volume. If the weight is 4.39 carats, the diamond concentration is 100 %, the maximum concentration is 400%, that is, per cubic centimeter of the segment, the maximum diamond content is 17.56 carats, according to the calculation formula of carat and grams, the diamond content of the percentage concentration is 0.878 grams.

Diamond is the main cutting part of the segment, so the more content the better? In fact, this is not the case, mainly for the following reasons:

First, the process of diamond cutting stone is actually relying on the exposed diamond to polish the stone through impact, so as to achieve the cutting effect. The cutting stone is actually completed by polishing, so the diamond segment is a grinding tool, since there is a grinding process, Then if the diamond concentration is too high, the more exposed diamond parts will be, which will cause the grinding area to increase, but will not play the role of accelerating the grinding speed.



Second, the diamond segment is sintered from both diamond and bond. If the diamond content of the segment is higher, the bond content will be lower, and the bond will be less. Then during the sintering process, the diamond powder and bond are mixed. It won't be too good. In the cutting process, the diamond segment is used on the sawing machine. The high-speed saw blade will vigorously impact the stone. If the bond is less, the diamond holding force will be weakened. At this time, the diamond will fall off. Cause a waste of materials.

Third, the higher the diamond concentration in the diamond segment, the higher the cost. The biggest cost of segment is the raw material of diamond. Although synthetic diamond is selected, the cost is still high. Especially in recent years, synthetic diamond materials have risen sharply in the market. If high-concentration diamond tools are used, manufacturing costs will be increased. Increase sharply.

Fourth, at present, high-concentration diamond sawing tools are mostly used in small brazing or electroplating processes. These processes are more resistant to high-temperature environments, and unlike sintered diamond segments, the high temperatures generated during cutting will cause the diamond powder to become carbonized. Happening. If high-concentration diamond segments are used, the requirements for mechanical cooling are very high. Once you don't pay attention, it is easy to cause the segment quality to become unstable due to excessive high temperature of the segment, and then the diamond will fall off, the segment will break, and the segment will lose teeth.



Fifth, the high concentration of diamond segment is also not conducive to later welding, because the welding surface will be reduced and the welding strength will be reduced.

Therefore, the diamond concentration of the segment is related to many factors. It is possible to adjust the concentration appropriately to increase the life of the diamond segment. However, if you want to improve the quality of the segment by increasing the diamond concentration, there is a kind of climb trees to catch fish & go south by driving the chariot north feel.
