1. Sintered diamond cutting pieces: divided into two types: cold pressing sintering and hot pressing sintering, and pressed and sintered.
2. welding diamond cutting pieces: it can be divided into two types: high-frequency welding and laser welding. High-frequency welding welds the cutter head and the substrate together through high-temperature melting medium, and laser welding melts the contact edge of the cutter head and the substrate through high-temperature laser beam to form metallurgical bonding.
3. electroplated diamond cutting piece: the cutter head powder is attached to the substrate by electroplating.
