Hard polishing generally refers to the use of hard grinding discs (Shore hardness between 80-90: such as resin copper discs, pure copper discs, etc.), with diamond polishing solution, a process for rapid polishing of sapphire substrates, window pieces, sapphire crystal polishing, optical crystals or compound semiconductor substrate materials (such as silicon carbide, gallium arsenide, etc.), etc.

Other typical applications of high efficiency hard polishing processes

C. GRISH high efficiency hard polishing program features

 The combination of compound metal grinding disc and high efficiency diamond liquid can achieve super high speed rate of more than 3.0um/min for LED sapphire chips, breaking the rate limit of previous water-based diamond polishing liquid.

 The new process of composite metal lapping disc can realize the capacity increase and reduce the machine setup and floor space.

 The combination of composite metal grinding disc and high efficiency diamond solution can achieve high removal rate and reduce grinding temperature at the same time, thus reducing the consumption of grinding disc and increasing the service life of grinding disc.
