Both cold pressing and hot pressing of diamond saw blades are common methods for preparing diamond saw blades.
Cold pressing refers to mixing diamond and metal powder at room temperature, adding a binder, forming by pressing, and then sintering to form a diamond saw blade.
The diamond saw blade prepared by the cold pressing method is low in cost, but its strength and wear resistance are poor, and it is suitable for processing materials with low softness.
Hot pressing refers to the mixing of diamond and metal powder under high temperature and high pressure conditions, and sintering by pressing under high temperature and high pressure.
The diamond saw blade prepared by the hot pressing method has high strength and wear resistance, and is suitable for processing materials with high hardness and wearability. But the cost is higher, requiring higher process conditions and equipment.
