Diamond blade for cutting silicon carbide is a kind of hot pressed sintered blade, which can be resin bond or metal bond with high sharpness and precision. Hub diamond cutting wheel is used for cutting off and fluting the large workpieces. If cutting small silicon carbide workpieces such as monocrystalline silicon wafer, diamond dicing blade is used for cutting.

About Silicon Carbide

Monocrystalline silicon, as an emerging third-generation semiconductor material, has excellent electronic and chemical properties. It is the preferred material for high-frequency, high-temperature, high-power, radiation resistant electronic devices, sensor devices, and excellent reflector materials selected by major aerospace powders around the world. It is also an ideal substrate material for manufacturing large-sized, ultra-high brightness white light, blue light diodes, and laser diodes. It has important applications in the fields of aviation, aerospace, intelligence, nuclear, energy, radar, and communication.

For these applications, SiC is usually cut into micro parts with complex microstructures or features. In addition to laser wire cutting and electrochemical microfabrication, diamond cut off wheel is suitable for cutting complex microstructures and micro components. However, SiC has high hardness and brittleness, and it will be cracks, which can lead to irregular brittle fracture of SiC material. Therefore, it need to study the stable cutting technologies and methods of SiC material to improve the processing efficiency of SiC.

Selection of Diamond Blade For Cutting Silicon Carbide:

Resin bond diamond cut off wheel has a relatively soft bonding agent, which makes it easier for diamond to expose and has higher cutting speed. But the cutting life is relatively short. Metal bond diamond cut off wheel has long life, but the bonding agent is harder and the diamond cannot be exposed timely, resulting in frequent dressing of blades to ensure the sharpness.
