When the cutting head processes the crystal bar made of the superhard material, the diamond wire is required to swing or the workpiece swings, so that the cutting capacity and the cutting quality are improved, but the existing cutting head swinging structure is very complex. Therefore, the integral cutting head is only suitable for processing hard and brittle materials with low crystal bar hardness, and is not suitable for cutting high-hardness materials such as silicon carbide, gallium nitride, sapphire and the like. Meanwhile, the existing cutting machine can only slice or square the crystal bar, and the function is single.
