Bury it. The explosive is then detonated by detonating a detonator, and the explosive force compresses and solidifies the powder. Hereinafter, embodiments will be described in detail based on the drawings.

A detonator 5 for detonation is installed on the explosive 4, and a lead wire 6 is led out from the detonator 5. now,
When the explosive 4 is detonated by the detonator 5 via the lead wire 6, the mixed powder 1 is instantly heated by the explosive force.
compressed and solidified. By removing the pipe 2 from this solidified product and slicing it to a desired thickness, the desired diamond pellets can be obtained.

合剤が使用される。First, as abrasive grains, in addition to diamond abrasive grains, cubic boron nitride (Cubic-BN), boron carbide (84G
), ceramic abrasive grains such as silicon carbide (SiC) are used. As the metal binder, metal powders such as iron, copper, brass, nickel, chromium, aluminum, cobalt, silica, silicone chain, zinc, and lead alloys can be used. The mixing ratio of the abrasive grains and the binder varies depending on the object to be ground or polished, and is a ratio of the number of abrasive grains to 40% by weight, with the remainder being the binder. In the case of the vitrified bond type, a vitreous bonding agent is used.
