For smaller or more complex diamond tools, a vacuum brazing process may be used to apply a diamond coating. The diamond brazing process is very different from the traditional electroplating process in several ways, however both processes will produce similar results.

Understanding the Brazing Process

Brazing of small or complex parts, such as NIABRAZE's diamond hole saws, preparation is critical. To provide a strong and lasting bond between diamond and tool, a clean environment is critical. Each part must be free of any dirt, oil, or debris before the brazing process may occur.

To begin brazing, a single layer of the desired diamond grit size and a metal filler material are adhered to the tool. The coated tool is then placed into a highly sophisticated vacuum furnace. Inside the furnace, the tool will be taken to very high temperatures. At extremely high temperatures, the filler metal melts into liquid form and is distributed into the small gaps between the diamonds and tool. While this process occurs, there is absolutely zero oxygen allowed into the oven. This is to prevent any oxidation to the metals inside, and ensure a strong bond.

After the oven's heating cycles have completed, the oven will slowly cool to around room temperature. When the diamond coated tools are removed from the vacuum over they will have a single layer of strongly bonded diamond grit.
