How to use and manufacture graphite mould in hot pressing diamond tools?
For the same diamond tools, the hot press is lower than the cold pressing temperature, and the time is short.
While in hot pressing, because of the sameWhen the temperature is heated and pressed, the temperature can be sintered as long as the bonding metal reaches the plastic body, so the temperature is low and the time is short. becauseThe compressive strength of diamond decreases with the increase of sintering temperature and time.
In cold pressing, the matrixTo sinter firmly, the temperature must be reached at the melting point of the bond metal in the matrix, and for a long time.
