The most delicate process in making a brazed tool with a PCD insert is the brazing procedure itself.
This is because the diamond cutting inserts, if subject to temperatures above 700 °C, they tend to turn into graphite, losing their hardness characteristics and consequently the tool life could be reduced as little as 60%.
When the operator has no instrumental control of the brazing temperature, he is limited to rely only on his attention and experience to prevent making damage. In case that happens, the only thing the operator can do is to unbraze it and replace it with a new insert. What solutions do you have to avoid this from happening?
