Laser Polishing Technology

Generally speaking, polishing refers to mechanical polishing using ceramic slurry and fire polishing mainly used in quartz and sapphire.
Polishing technology using laser has often been technically mentioned, but it has not been applied to industrial sites.
Accordingly, 21C realized the need for polishing technology to correct the fine flatness after precise grinding.
Therefore we developed laser polishing equipment in cooperation with overseas leading research institutes and applied them to industrial sites.
Laser polishing technology is a unique core technology of 21C, and it is being used in various fields such as large-area polishing, fine correction after grinding, and patterning technology.
