Advantages and Prospects of Brazing Diamond Tools

In the electroplated diamond tools, diamond can only use metals as mechanic coating, which is easy to fall off, and it has disordered arrangement, low bulge, and little space for chips. In the impregnated sintered diamond tools, the self-sharpening problem is difficult to solve, and diamond is also difficult to realize metallurgical combination with powder. Both of them are not fully and effectively show the cutting performance of diamond, while brazing diamond tools have the incomparable superiority compared with the above two kinds of diamond tools. Therefore, diamond brazing technology has caused people's attention in recent years.

The diamond surface metallization technology helps to weld diamond with active or nickel-based brazing filler metal and make diamond tools and tire body achieve metallurgy chemical combination through adding strengthening carbide forming elements or alloy, which can improve the holding force of diamond. Diamond can protrude about two-thirds and is not easy to fall off, which creates sharp cutting, good chip removal and other favorable conditions. And the uniform and reasonable arrangement of diamond on the tool surface, makes full use of the cutting action of diamond, saves the dosage of diamond, reduces the costs, and improves the cutting efficiency. It also conforms to national economy development in our country, vigorously saves energy resources, and speeds up the construction of resource saving and environment friendly society's requirements.

Brazing can help to realize the chemical metallurgical bonding between diamond, binder (brazing alloy materials) and metal matrix, and has high bonding strength. Compared with the electroplated tools, brazing diamond tools show incomparable advantages, and will become a development trend in the future.

As new generation of superhard material tools with excellent cutting performance, brazing superhard abrasive tools have broad application prospects, whose successful development not only can improve the research level of domestic superhard material tools, but also bring new economic growth for the domestic abrasive industry. At iAbrasive.com, there are some great diamond tools suppliers that may supply them.
