Concept of diamond tools concentration
Publish Date:2020-09-02
When the volume ratio of diamond in the matrix is 25%, the concentration is 100%.Concentration is one of the important characteristics of diamond tools, which has a great influence on the efficiency, life and processing effect of the tools. Generally, if the diamond concentration is high, the number of diamond particles per unit area of the working layer is large, the force of each abrasive particle is small, the depth of cutting into the workpiece is small, the diamond is not easy to break and fall off, but it is easy to be ground and polished. Low efficiency and long life; low diamond concentration, each abrasive grain has a greater cutting pressure, deep cutting, diamond is easy to break and fall off, the tool is characterized by high efficiency but low life.
Generally, the diamond concentration of sawing tools is mainly use 10%-45%; the concentration of drilling tools and sintered metal bond diamond abrasive tools is mainly use 50%-125%; the concentration of resin diamond abrasive tools is mainly use 50%-100%; concentration for ceramic diamond abrasive tools is mainly use 75%-150%; concentration for electroplated diamond tools mainly use 200%

The development direction of diamond tools in the natural stone and civil engineering industries
2020-05-27
Abstract: Metal-bonded diamond tools were introduced in the natural stone and civil engineering industries for processing decades ago. Undoubtedly, their use has brought revolutionary changes to material removal and increased processing productivity. However, although tool performance has improved significantly However, the main factor limiting the widespread use of diamond tools is the high price. Therefore, it is particularly important to fully understand the principle and grinding performance of turning. It is true that one can predict the best processing conditions, but the grinding process Cutting knowledge is the most basic condition to achieve the best machining size and improve diamond performance. This article gives a brief overview of the processing principle and related tool and process design. Considering the stone and civil engineering industry, some diamond tool development directions are also done. Briefly described....

The volume ratio of diamond in the matrix is called the concentration, and the concentration can reach up to 400%, but this is an ideal situation. For most diamond tools, the concentration of 300% is already considered as the limit. At present, The concentration of brazing products is the highest....
